Did two fixes on separate (I think) issues. Fixed the primary carb float level from almost 3/4" to very close to 1/2 inch. Road tested to full throttle in low and second. Wound right up to 5,000 rpm with no miss and no loss of power, starving for fuel.

Second fix was to verify continuity in the plug wire and replace the plug on the one cylinder that showed a sooty, oily plug. After running a bit, that seems to have fixed the missing at low rpm.

Next I will adjust the idle circuits to be sure they are not too lean.
