thanks again for your help sorry it is takeing me some time to reply.
I tried replacing the decompresor with a spark plug and it still dose not run, there is alot more compresion with no decompresor.
I can't find any leaks in the intake hose.
it doesn't even fire and now I think about it I dont think it has since the first day when I could only get it to chug.
I have checked for spark a coupple of diferent times by removing the plug, conecting it to the spark lead, holding the plug against the head and turning it over.
the primer bulb is now split, fule doesn't leek out, should it still run with it split?
I have tried rotating the fule bowl cover a little clockwise and anticlockwise, still no go.
i have checked the brass jet and the plastic jet for blockiges by poking a small wire through them.
any other ideas
thanks
SB
