What is a good premix ratio? cuz the previous owner was a moron and was using 1 oil : 5 Fuel causing it not to start correctly and producing a big blue cloud of smoke coming out the exhaust for like 3 minutes until it will run properly... What is a suitable Oil to Fuel ratio for a 70cc piaggio zip ?
33:1 - 40:1 id run 40:1 you say the last guy ran 5:1?! fuckin hell, so he put a litre of oil in 5 litres fuel?
thats one really sooty motor, i would strip and clean the top end, one day i will get a photo from work of cheap oil and what it does to your motor!
Yes, he run it 1:5 causing a big cloud of blue smoke to come out the exhaust when left over the night and it won't run until the leeft over oil is burned out... I could sit on it pull the throttle all the way and it wouldn't produce any torque at all just wouldn't move at all for like 3-5 minutes Thanks guys!
And as much as I would love to strip it down and clean, I'm not capable of doing it myself (I'm only 16 and started mechanics college will be able to do it eventually) and local mc mechanics/garages will charge me silly amount!
its easier than you think to strip a two stroke engine, at work we get it done in an hour, strip and rebuild, the worst bit is removing all your panels. you got a good career choice, im a mechanic and started when i was young. get in contact with some race teams, they always want extra help for little jobs and its amazing experience
Yeah but don't want to do it until I practice at college, as I need to use my ped for work everyday... But sure will try it at one point!
yeah, although you always run the risk of finding more work than you planned for. might be worth taking the plug out each morning if its easy to get to and kicking it over a couple of times with no plug.
What will that do? Edit: I reckon cuz his ratio was too torch I'm better off getting a new spark plug to as this one could me covered in all that black crap...
same, but seriously, stripping a smoker engine is a howling piece of piss once you know what your looking at. just start the strip down on a friday night, then youve got all weekend for the rest. even if you dont strip the engine, just take all the panels off one day so you can learn how everything fits. I doubt youll need to strip the engine anyway, just really dilute the fuel so it has less oil in it, then let it tickover for a while so it can clear itself
eh? 2% of what? 2%petrol:4%oil? just use 20ml of oil to 1L of petrol which is aparently what the standard pumps put out
