Getting ready to put Miss Scarlet to bed for the winter. Dumped about 3 oz. of STA-BIL in about 1/4 tank of gas and drove about 1 1/2 miles to the station to fill the tank. Then I drove another couple of miles into town. On the way back home she started running like crap. She will start and idle just fine. I was able to get home by letting in idle in third gear. So, it is not load related. In neutral it will surge in a rhythm if I try to hold a higher RPM off idle. If I continue to try to increase RPM by pumping the pedal it will eventually die. It is not missing like an electrical issue. There isn't any misfiring. I'm thinking some sort of fueling issue. She has the original Aisan carb that was worked on in 1997 by the original owner. It was also desmoged at the same time. The fuel filter was changed in June of 2017. Been running like a fine watch since purchase in May of 2017. I can't believe the STA-BIL is the issue. I'm starting to suspect water in the gas, but I bought the gas at a Love's truck stop so that really shouldn't be a problem. I did add a bottle of HEET just in case, but it is still running like crap. What say you oh wise ones?
