I had the same problem and was getting quite frustrated and I read here that someone recommended an O.S.8 glow plug and it was like night and day.I very seldom have to tune it from one time to the next and it performs flawlessly.Because of the hotter plug I can run it on the richer side and the temp runs between 240-270.I found that if the truck stalls at less than half a tank it will loose prime at the carb and you will have to hold your finger over the pipe as to put fuel back to the carb.But you better be wearing gloves or use a rag as the pipe gets very hot.If it does stall and your close to the truck you can see the fuel drain back.Someone here said they went to a smaller engine to get away from tuning issues.I can't imagine having anything else in this truck for power.I say if lots is enough than to much is just right. Hope this helps someone else, like it helped me.Thank you.
