I am posting a further update on this in hopes it may help someone who might experience the same issue. I have continued to have issues with no power coming off of idle. I had replaced both the fuel pump and the distributor but continued to have issues. Engine starts fine including the choke operation and fast idle setting. Everything normal until you put it in gear and try to move off idle and the engine would stumble with no power. Top speed was 15 to 20 mph and I was afraid I would not make it home if I took it out to test drive. On test drive I discovered that if I put the pedal to the floor it would accelerate to 65 mph but could not cruise or maintain any speed. Only accelerate at wide open throttle. My driveway has a slight incline and sure enough I could not make it up the driveway. In desperation I put the pedal to the floor, it stumbled and then came alive and I did a burn out half way up the driveway. With idle good and appearent power from the secondaries I now assumed it had to be carb primary circuit related.

I called Ken Frey to see if he could look at it. Although he was trying to wrap up and get out of town for the holidays, he said to take the carb off and bring it over. I got a good education on Q-jet. We disassembled, inspected, cleaned, and reassembled. Nothing was drastically wrong but it was dirty and gunked up inside. Carb was fully rebuilt by Ken in fall of 2014. I have two filters, one in the carb and one before the pump. I also keep tanks full, treat with stabill, and run every 30 days.

Anyway, I installed the carb with a new base gasket and torqued the 4 mounting bolts to 10 lbs. After making all connections it started fine and I went out for a test drive. I had good power across all RPM ranges including climbing some pretty good local hills.

I hope this carb cleaning is the final fix on my loss of power issues. I suspect ethanol gas may have something to do with it.

Many thanks Ken and to all who provided ideas and assistance. I am back on the road again.
