How to replace gaskets? By FACE PLANT FOR LIFE (Read 1,476 times)

From what I have seen the ciao has a similar "rotary volve" like the other 2 cycle vespa scooter engines including my tx200 . LML went to a reedvalve which is abit better to my undertanding . LML also went to a 5 port engine cylinder and crankcase on their lml star and stella 2T engines. Very interesting on the difference in the portings on the old new and lml engines.

Got the new cylinder gasket put on, got the engine back up, clutch reinstalled, exhaust on, spark plug in, whole engine assembled, yadayadayada. Went to go start it and....NOTHING. Still no fire. Piston looks great, rings look great, cylinder looks great. We have TONS of spark, we have fuel going to the carb (unsure if it's coming out of it, though...), and we have 115LBS of compression (no change from the gasket installation). I'm really at a loss here guys...

Squirt some fuel in there with premix . See if you can grt it to sputter .

pull the plug and put a teaspoon of premix in the cylinder button it back up,,lite that puppy

Premixed did nothing. I think it has more problems than we know. We're just going to sell it. It's already on Craigslist!

Unfortunate, really.

I don't know if you soldit yet,,, if you havnt check the flywheel where it meets the crank ,,, maybe someone that was working on it put it back on with no woodruff key and the mag is out of time,,,, worth a look

[FACE PLANT FOR LIFE]

Hasn't sold yet. All I can do is take a look.

you got gas you got spark you got compression,,,,,,my money is on the mag being out of time

Cyborg, the problem with these things is that the timing is controlled via internal switches. You have to split the crankcase to get to the "points", and even if I did that, I don't know where they SHOULD go. The previous owner replaced the "points" in it, and he said that didn't help. But he may have made another problem by putting the points back into the wrong positions. To be perfectly honest, splitting this engine is not on my todo list. I'd rather get the Xbox 360 I got for $25 to stop overheating >.>
