Cleaned carb but now having problems starting

Thanks mate I cleaned a few fuel pipes and recharged the batt and tuned the carb and rev cable a bit and seems sound now, had a go and runs fine. Just noticed that me speedometer isn't working tho. Took the front wheel off and that seems like it can only connect 1 way and took the front panel off and it's attached to the back of the meter and seems to be turning ok but won't read my speed. Any tips mate?

 

Have a look at what way the speedo drive turns when her spin the wheel... Take the inner out and feed it in to the back of the speedo....give it a few good turns by hand..if the needle flickers then its just an matter of fitting it again carefully..if it don't spin your gauge is nackered...or could simply be the cable is broke

 

Will have another look today as it was dark by time I'd finished. Thanks mate

 

had everything off this morning and it all turn from both ends. connected it properly. even spun the cable from the bottom by the wheel and the clock flicked a bit. however when i took it out its still not working :-(. even went so far as to bang the clocks with me hand while riding incase it was stuck! nothing

 

Has the speedo ever seen to be working..in one of your posts you say you've only had it 3 days..maybe it ain't the right length inner..or the groove were it slots in at the wheel end is too deep and is causing the inner to slip down farther and then not be connecting in the speedo end..if both ends are working...which it seems is happening..the only thing I can think is its too short or needs a wedge of some kind to stop it slipping..if that's happening!!..try this...put the cable back in the outer cable and firmly screw fit it into the speedo so that spinning by hand gives you a flicker.but do this at as near to its fitted position as possible.then check how much room you need at the wheel end for it to fit..reconnect and try again..if it don't work .you now need to check the end that fits to the speedo end for length..it could be that bending the cable is slightly making the inner recede into the outer and disconnect from the drive..had that problem with a cheap dremmel type flexible drive.both ends are working..cable too short or outer been replaced with one too long.may be a case of keep trying and/or do some inner/outer cable swopping

 

I know exactly what you mean! Had a lecy screwdriver turning the cable today from the bottom end by the wheel, the clock started moving great, took the front wheel off again and made sure it was all connected which it seemed to be. Will have another look at in tomorrow as I haven't had much time today. Also took the bike out for a spin and came back and an hour later it wouldn't start, noticed that my air hose running from mr carb was ripped so I've taped it all up, tool the carb out drained it and cleaned it. Gonna put it back in and see what happens. Also put new brakes on her today so I've been really busy haha. And yes mate I've only had it about 6 days now and it come with a flat tyre on the front that wouldn't keep air so I had to buy a new tyre, so I don't know if the speedometer actually worked before I took the front wheel of to replace the tyre. Always seems to be 1 step forward 2 steps back. Appreciate the help and advice as always mate ;-)

 

Welcome to the world of scooter ownership.so long as the wheel end turns the drive your almost there...just gotta tie the two ends together.if you got any rips in the carb hoses..best to change them..may not seem that bad at first but only gets worse over time and may upset the filtering and screw with mixture leading to poor running.know what ya mean with the one step farward thing,I've gotta get on the case with mine soon..did a tiny bit more on my vision today...getting grief from the g.f..best motivation in the world..nag.nag.nag..think she needs a rebore..

 

hahaha ano what ye mean mate.looked it all over again this morning and everything seem to be connected its driving me nuts.would buy parts but dont know were to start as it all seems to be working when i turn it but not when i put it all back together.got the carb on and all me hose duct taped up to f**k but now it wont bloody start. got spark and compression so it can only be no fuel in the carb....right? haha

 

Well you look like you still got a sense of humour.have a go with the carb clean out and if your up for it...empty the tank and give it a good swill out too.then have a go at starting it..dunno if you've checked the diaphragm or not(top of the slide)might have a hole in it..if your still having grief after changing the plug and doing a clean out...see if you can get another coil...had similar problem and new coil,lead,cap and plug sorted it

 

Alright bud sorry for the late reply, had a few days off and stick her in the shed. However went back today with a fresh mind and sorted everything out. She's running fine apart from my revs are high on the carb. Needs adjusting a bit. Do you think it would be worth me taking it the shop and getting me carb tuned?

 

The carbs on most of these PEDs are simple enough to sort out but its a bit tedious to get it to set up bang on without a few simple bits of kit.for the price a shop will charge you get a simple co2/Mno2 meter and do it yourself to a good level.but the simple way is to screw the air screw in till it stops and then wind it out 2 1/2turns.then adjust the screw on the cable cam on the carb end till it runs smooth.then screw the air screw in and out till it runs at its fastest with the minimum of turns...then readjust the throttle cam screw for a steady tick and repeat till your revs stay constant and steady.you could do the plug color thing but that needs to be done ideally with a fresh plug each time.if your exhaust is large enough to stick a probe in...have a word with the local mot man and see if he would do a quick check with there probe.then all he has to do is turn the air screw till the reading is within reasonable limits.bout a 20minute job maximum.a home co2 meter ain't too expensive and having one is handy if you do any mods and have to rejet at an time

 

Thanks for the tips mate, will have a go at that today. I know what your on about mostly cos I've done nothing but mess with it for a couple of week. Only need the carb sorting out and me bike is good to go. Appreciate the help as always mate ;-)

 

right ive started it today and loads of petrol has pissed out of the air filter box.lost half a tank lol. anyway took the top off the air filter box and drained it and then the pipe that goes from the bottom of the air box to the front of the engine (by the spark plug) pisses out petrol when i start it. is this my vacume tap?

 

That's the head breather pipe..there should be 2 pipes on the petrol tank.1 goes to the carb manifold between the engine and carb and the other goes to the carbs petrol input one side of the carb.the pipe that has petrol coming out when you suck on the other goes to the carb and the suck pipe goes to the manifold..looks like those 2 have been reversed...should also be 2 other pipes on the carb...top is over flow pipe and bottom is a drain pipe..sounds like you put some pipes around the wrong way.

 

I labelled them all before I took them off mate so I'm sure everything is on right. Well mostly sure lol. Someone on google says it could be the float on the carb not shutting so I took it all off again and that seems to be all as it should ( I think) so I've ordered a new Petcock and a carb rebuild kit off eBay and see how I get on. What you think mate?

 

Well the carb kit is a good idea if your having any probs with it..rules out any future issues.the pet cock...mmmm if you got a rip in the diaphram then its gonna piss out of both pipes and cos the vacuum is connected to the manifold its gonna come out and be directly going in the head as liquid not as a vapour via the carb in the usual way.if you remove the vacuum pipe and blank off the tank and manifold holes it would run OK but the petrol on off will be governed by the carb float so if that gets stuck down at any time its gonna piss out petrol.good idea if you take out your plug and kick it over a good few times to clear any petrol in the head and remove your exhaust pipe to clear any petrol that might be
lying in the system too..

 

Didn't really understand a lot of what you meant there tbh mate. (Sorry I'm very new to scooters) is the diaphram the big rubber like sock thing in the top of the carb? If so I've had it out last night and it's in great condition. Not even a pin hole. Also when I look down the main holes on the carb ( manifold& airbox) the rubber thing doesn't shut all the way! Is it meant to be like that. I can see the pin at the bottom aswell. And I carnt get my exhaust off cos it's so rusty an the bolts are rounding off. What do you recommended I do today while I'm waiting on new parts? Take the spark plug out and kick it over a bit did you say?

 

Hi ..keV.the diaphragm I was on about is the one in the fuel tap/tank.what happens when you kick it over is a vacuum sucks the flap open and petrol flows...if that is knackered then there's no valve system to stop petrol coming out. And it just flows though all/any pipe it can.as one of them is connected to the manifold(to get vacuum)and its after the carb...it will piss petrol into the manifold and thats on your head.when its working right...the the carb gets the petrol through the other pipe and stop/starts via the float at the bottom of the carb.looks like your gonna have fun getting that pipe off at some stage..good luck with that one..if you do have any petrol in your exhaust pipe,chances are its gonna be mostly evaporated by the time you get the petcock and carb kit fitted..or..if its got loads in the exhaust pipe.tip rear bike up on its back wheel as long as you can to get rid of the main bulk and hope any left overs evaporates off as you go.

 

If you wanna blank off the manifold pipe both ends and give it a try starting..the petrol should be OK to evaporate as if needs a lot of heat before it catches fire.but an extinguisher might be a good idea if your not comfortable doing it.

 

I know exactly what you mean now mate. Waiting on the pet cock in the post so I will fit the new 1 and go from there when it comes. Don't think it's the carb like. Got me new speedo cable today and I think I've fixed me speedometer but carnt be sure until I give it a run. Which I carnt till I've fixed the petrol issue. Got a new air filter to go on aswell but will also wait till I've stopped the juice pissing in the airbox hahaha. Cheers buddy will get back to you on mon/ tues when the pet cock gets here
