to jamie and Ron Brown

Hey guy thanx for the help. I turns out that it's not the decompression valve, thats in place and working. this hole is on the side of the piston housing and i can see welding residue around the hole. as i pedal, gas mist shoots out of the hole. my question now is, Do i try to weld the hole up or do i buy a new housing? and if i buy a new housing, where can i get one(i dont know which model it is, it just says motobecan with no number)?

Ouch, do you mean the cyliner?

It does not sound good, take off the head and cylinder. Welding is out of the question.

After you figure out what you need, post a Motobecane Parts question and hopefully someone will respond.
