An old roommate once told me I messed up my timing on my two stroke (1E40QMB) scooter. I took it apart to the piston, but did not remove the piston.
Somewhere else I read you could'nt mess up the timing if you did not take the piston out
Would just like to confirm from you guys,
Thanks as always!

I dont see how you can change the timing unless you are replacing the flywheel/crankshaft.

Messing up the timing on a 2T takes a lot more work then that, it involves crowbars, hammers, and even explosives.

The only timing you can possibly mess up, with removing the cylinder, is the port timing. To mess it up enough to cause real problems you'd have to put it together with many extra base gaskets. No base gasket wouldn't "mess" the port timing up enough to cause issues, unless it's a highly tuned race machine.
Sounds like your roommate didn't know much about 2 strokes.

If you have a 2stroke motor it will only have reed valves. They go between the intake and the case. Some people tune them by using different thickness of reeds. Generally thicker for higher rpm. Not something that requires regular tuning, once they're set to seal properly you can forget about them. There also isn't a spec, either they seal or they don't.

LOL yeah i was pulling your leg sorry. i have the Tomos TSR with the oddball 1E41QMB engine i am putting in a 70cc top end and carbon fiber reeds, also a new performance exhaust because Tomos exhaust only works with a Tomos cylinder if you can find one.

On that Colorado good stuff This same roommate decided to JBweld the drip hole on the bottom of the carb. And I've been looking at new carbs and whats the purpose of the line that goes from the drip hole? He got it to run once, but then my other roommate took it for a ride and it stopped working. All while I was at work.. So after leaving the place I decided to tear it down all the way to really learn about this scoot. This was a yardsale_scooter_paid_40_dollars. Added 285 in parts. Learning how shit works: Priceless _

The hose from the drop hole is so gas from the float bowl diesntdrip all over your cvt case & tire, which will attract and hold onto dirt & debris. Can you find a drillbit small enough to drill through the jb weld?
