Thanks here is the info
I purchase this moped new in 2004
It has 1600 miles on it
The Decompression was a little rusted i clean it up verify it was seated in the New head.
What timing it is a 2 stroke ?
I install a new spark plug Ngk Same number that was in it I don,have the number handy as i write this.
i verified that the piston was install right arrow to the exhaust
As far as the valve it was recommend that i buy it to keep the fuel in the cylinder to keep it from seizing up on shut down .
I did not replace the carb I did blow it out
I could not get the air filter back on it even after removing the carb.
I did not tourke the head bolts because I could not find the settings I have the tool to do it. I tighten them until i though they would brake
all nuts, bolts, washers were replaced
This unit sat for over 13 years after it seized up My son used the 4 cycle gas
I replace the gas tank. The frame was rusted inside
I replace the engine coil with on from a 50cc scooter plenty of spark after replacement.
with the choke on it starts with the first kick with the choke on i never needed the decomp
it will sit and run for 15 min at idle until i turned it off
the original plan was have a motorcycle tech to do the work he has a few of them he got back up with other work i thought what the the heck i have done these before but this one got me stomped
i have rebuild small engines including bbk on scooters for years i went that route after the this unit seized up.
I hope this gives you some back ground on this unit
