39 Heasitation
39 in Penna. hasn't been run much over the past few years.
Due to Mercedes daily driver having brake problems it was tied up for repairs a few days and needed the 39 for transportation. Had a little compression leak as described in another thread and added a bottle of K&W block sealer which took care of that problem. Then the 39 started with a hesitation when the gas pedal was pushed. Drove it about 50 miles and it the farther I went the worse it got. Back home I thought the generator wasn't working and the coil voltage was getting lower and lower. Put voltmeter on and had close to 9 volts with some engine RPM's. Checked the carb adjustments and idle was a little fast and the mixture valves were out about 2 1/2 turns from when I got it right. This was a Ford carb and Stromberg was sitting on a bench near the front of the car. I guess I had carb trouble on the road a few years ago an stuck the Ford carb on to make it home. The gas in the car was a few years old and very low, I had another can of non corn gas with about 2 gallons in and dumped that in the tank which had non corn gas and added some MMO. It was still hesitating but a little better. A few days ago put 10 gallons of no corn and drizzled some MMO down the carb and it now only had a slight hesitation. Drove 60 miles to Hershey this morning with still slight hesitation. On the way home after 90 miles on the last mixed tank of fuel stopped and filled it, it took 8 gallons. After about 2 miles it completely cleared up and ran perfect the last 20 or 30 miles. With all the missing problems posted on here some could possibly be old fuel related. G.M.

Re: 39 Heasitation
George, I had a similar problem with my 77 F150 and 39 a well. I have since added the Star Tron fuel treatment on fill ups and have been getting my fuel only @ the local BJ's club station were I fuel all our vehicles now.
Stale fuel it sound like. Keep us posted and give that 39 a little more "love", hire a buddy to drive it once a month. Scott |

since he was little on home repairs and car projects. I let him drive home about 60 miles. He has a key to the garage so I'll let him drive it once in a while. Half way home we stopped and I filled with 90 no corn and in less than 2 miles the hesitation was completely gone. Old fuel could be the cause of many of the hesitation problems posted on here. G.M.
