Fresh rebuild, running mostly great, stock. About 700 miles now. Spark timing @ +20 BTDC, #1.
About 2500 - 2900 a little stumble. Occasionally idles low after medium accel letoff coming to a stop.
Seperate little thing-Also tach may not move on engine start, jumps to current rev and Ok from about 10 seconds after start - sometimes a little rev kicks it in.
Thoughts?!?
