I have a 1963, 650, Magnito Ign. Upon startup the engine idles fine until it warms up. Starts great, choke on until it fires, then no choke and idles a little high.

Run it down the lake for a few miles, pull into dock, have to use the fast/warmup lever to keep it runing at idle speed.

Carbs checked, float level good, fuel pumps rebuilt with new check valves and diaphrams. Points set at .010", timing 27 degrees BTDC at WOT.

I can deal with it this way, but someone (adult kids) are at a loss docking it.

Got a be Carb related, right?
