Brooklyn: Thanks for your comments regarding my cam synch change. I think now I possibly was not at TDC when I set it. The engine is running better than before but still exhibits these symptoms:
1. Bucking at cruise and light acceleration.
2. Occasional backfire.
3. Somewhat sluggish.
What I did to try to reach TDC compression stroke was remove a plug, and bump the starter until I felt the compression in the plug hole. Then I put a long screw driver in the hole, and hand turned the crankshaft, but the screwdriver never moved. I got the impression the plug hole is at a steep angle to the piston and the screwdriver was just going in toward the far cylinder wall. Is that correct? I was able to at one point feel what I thought was the screwdriver blade sliding across the top of the piston, so I thought I must be close.
Then I looked down at the engine from the left(facing engine) and could see a sensor over a notched wheel behind the crank balancer. There is no pointer for timing so I am assuming(probably wrongly) this sensor is the pointer. Anyway the degree marks were visible on the balancer near this sensor and it was about 10deg. I then turned the crank by hand to align the 0deg right under that sensor.
Did I do this all wrong?
