Newbe, I just started to tinker with my M715 yesterday.
Any suggestions on the best place for parts?
How about a spark plug wrench?
Truck running very rough, I think it may be a fuel pump problem.
Similar to a recent post I just saw here 'Truck runs like crap...'
Dumped the fuel and replaced, checked the carb, looked good and clean.
Checked distributor, looked pretty good, cleaned contacts.
Can't get the plugs out with the tools I have to check them.
Wires looked good.
Pulled fuel pump off and checked internals, pump looked intact and looked clean, no tears in diaphragm, but actually found a small piece of spring (.5 inch) stuck to arm, not sure where it came from, unless old pump had broke and been replaced and piece of spring was left in cavity. Seems to be spring from underside of pump arm. Possible that spring broke on current pump and spring reposition itself in arm as it expanded.
Are there any springs from where the cam makes contact with the pump arm?
May go buy an electric fuel pump and see if it resolves the problem.
It seems some people replace the original with an electric anyhow any particular reasons?
