Glad to hear somebody out there has parts.
I've done just about everything I can think of, but I am a novice. I had the magneto apart and cleaned and set the points. It gets spark in the right order and I aligned the spark timing to the timing mark on the flywheel, so I think that's all set. As for the strength of the spark, it's a little suspect. As I said earlier I get consistent blue sparks, but jumping 5/16" seems very far. I doubt it would be able to do that, but who knows.
Other things I've done:
Cleaned carbs
All new fuel lines
All new sparks
Tested lines from magneto - all good
Tested compression - good
I have been trying to run it without the fuel pump attached by just hand feeding it with the primer bulb. Could that do it? I assumed this wouldn't cause an issue as long as the carb reservoirs were filled (they were)
