I just purchased a 1973 Ford F250, that has been rebuilt. It has approximately 3,000 miles on the engine. Its a 360 2 bl carb. We had an extremely hot day today when picking the vehicle up. 95 degrees and humid; the truck was running smooth at all speeds until coming back from a 20 mile trip on the highway going 65mph the truck started to lurch or jerk. This continued on an off for a couple miles with the truck losing power and momentum until the engine would stop. I would put it in neutral and it would restart with applying gas, but continued this progressive slow down and repetitive engine killing until we could depart the highway and to a Ford dealer. We sat for about a half hour and I restarted the truck and drove around the parking lot with no noticeable effects. Is this a vapor lock; or somekind of fuel issue? Or could this be a transmission problem?
After a while, we adjusted the carburetor less lean and then drove it home about six miles with no problem?
have the same problem?
