onder2:sounds like the sphincterdoodle spring is bad and locking to the muffler bearing
:jk:
on a more serious note ,it maybe your clutch spring broke and is hitting your clutch bell
and is it running when it is doing this or just when you pull the cord?
Took the clutch bearing off and re-lubed it........put it back on and everything seems to be working fine again.......think I will order a new one just in case......thanks for the help.....gotta stop spending so much time with this car.....haven't flew my planes in over two weeks........I think I'm hooked.
