the new - what have you done to your ped today thread.

Good Karma dude

 

fitted the new inlet, old one wasnt actually split all the way through but still needed replacing. Checked my reeds too, still no fuel getting through, im pretty stumped. Sometimes when kicking it there's a big gust of air out of the exhaust, what could this be a symptom of?

 

Parts arrived for the two vx's in the garage, will get fitted tomorrow, cleared out the storage side of the garage, scrap man had a field day, frame, engine, gearbox off the old porsche, huge air tank, various other metal stuff that aint ever gonna get used again. Chopped up loads of plastics off various different scoots and binned them ready for the trip down the local tip. They've been advertised but no takers, so destroyed they got.

YAY ME...............SPACE..............for more scooters

Ordered the new decals for the Zip, all in black. Planning to paint it over the weekend, gonna be brilliant white with black in strategic places, and only a smidge of decal stuff. Should look nice. But you know what happens when i make plans...............some bugger comes along and screws them up.

Also ordered the decals for the Katana, in gold, and four for the wheel rims in black, cos they are going to be gold wheels. Damn things so close to being finished i can taste it.

Dragged the lawnmower out, petrol driven of course, promptly broke the starter cord, fixed that, cut the three lawns on the front last night, finished at just gone 8pm, and the rear lawn tonight. So no scooter work done last night or tonight.

Now having dinner whilst doing this.............a whole lemon cheesecake

 

Low compression? Not sucking enough fuel to the piston to start but enough to give the fart.

 

i'll do a compression check hopefully tomorrow, if i have enough compression, what could the case be? air leak? stuck needle valve/float?

 

Daft question - have you got the depression hose & the fuel hose swapped around ? With the carb disconnected- when you blow/suck/blow/suck on the depression hose, does fuel come out of the fuel pipe ?

 

time to bleed the brakes, then its off for her MOT

yippee, soon to be back on the road

mark

 

thing is, i didnt touch any of the pipes. It was running fine!

 

Ah. So try it anyway- that will tell you if your depression stop cock is letting the fuel out. Then you can move on to the carb.
They often lock up and give trouble. Also, try loosening the fuel cap. If no air can get in the tank, no fuel can come out.

 

noob question? is that the vacuum pipe? There is definitely fuel entering and filling the float bowl

 

Ah. But it's not starting. It flatly refuses to start or it goes a bit and dies?

 

refuses, the plug is dry no matter what i try, sometimes there's a shot of air out the exhaust

 

I would clean the carb (I imagine you've done this already). If so, I would look at the reeds or try another carb. I hesitate to say 'ignition' because that usually gives you a wet plug. Does it start if you give it loads of choke. Do you have a manual choke? Are you sure your clutch bell is on the crank tight and properly aligned? Have you checked?

At this stage of fuck up, I would have the engine off the frame, check every single system, ignition, fuel supply, carb front to back and rebuild (without actually breaking the engine in two, but at least with cylinder off for a check up).

But if there is fuel in the bowl, it should go. And so I come back to ignition - CDI or the rotor which is off. But even then in should start..... But not if it's the CDI. But if it was, you wouldn't get spark. If it was the coil you would see a wet plug, just like the CDI.
or an air leak so big it won't go even with choke. Which is near impossible.

Strip down, clean everything and scrupulously rebuild. But do the suck/ blow test with the carb disconnected first, and try another carb if you've got spark. Don't know what else to say.

 

i've looked at the reeds and nothing seems wrong with them, what shall i check with them? And it's auto choke

 

I don't think the auto choke would do it. How is your oil situation. Is the engine hard to kick over? Have you looked at the piston recently? Like I said- with this level of fuck- up, it's time to get down to first principles and dirty hands.......
But before that, a different carb and a change of spark plug, a general lookover. There's nothing blocking the exhaust is there ? Clutching at straws here......

 

engine feels as normal to kick over, its quite a mystery

 

If I lived within 100 miles I would make the drive and strip that fucker. But there is more than miles between us. There is Sea. I suggest you seek professional help if you've tried everything . Make damn sure you try everything. It's disgusting to hear that it was something you could have found yourself and then be presented with a big bill. This is why I am on a forum, and why I determined to never let it happen again.

 

i won't give up. What DID you touch?'

 

All i was doing was trying to figure out what noise was coming from the variator casing, i took this video -



shortly after, i washed it, went to go out for a ride, i remember a shot of air came out of the exhaust but i wasnt sure if i heard it properly so i carried on, shortly after i just lost power for a few seconds and it cut out, must have covered about 200m from where i left and where it cut out...

After that i thought, maybe there's some water that got in somewhere, so i checked the HT lead, drained the float bowl, inspected the air box and filter. No water present. After that i cleaned the carb and jets out, and most recently, replaced the inlet manifold and checked the reeds.
