Hi guys,
Restored an old Sahara 150cc GY6 and got it running today. I drove it about 40m and it backfired/popped and then conked out. Now I cant get it to start.
I have checked timing, there is a spark but wont ignite, I'm completely baffled....
Thinks I'm NOT sure about
It sounds like air is being vented from the exhaust (may sound stupid but it didnt sound like that before)
The large hole on the cam sproket is aligned with the little ones and the 'T' on the flywheel.....but it seems to misalign itself after a few times of turning it over (by 180 degrees?)....Chain tensoner seems to be working (although has no spring under the screw top).
Today was supposed to be finishing day, and got just 40m out of her
Hoping someone can suggest some other things to check?
Many thanks
JB
