Re: Erratic problem
MMO in the gas tank will clean the lines,pump and carb. On the first application drizzle some down both sides of the carb while running then put a 1/2 quart in the tank reguardless of how much fuel is in the tank. It will smoke but it will remove the hard white resin on the valve stems and free the rings. About a 1/2 pint every time you fill the tank after that. I drive 6 or 7 old Fords and if MMO is not added the valves slightly stick after the second tank without it. This sticking is very slight and most people if their engine is not running perfect will not notice it. The most noticable test is in high gear, drop down to 8 or 10 MPH in 3rd gear and step on the gas and as the speed increases you get a bucking, after treating with MMO in 10 miles it will pull out smoothly. Reds with the changes you made it sounds like dirt in the gas tank plugging the pick up tube. I just had the same problem and when it is intermittant it is had to detect the problem. I went 1150 miles, the 1st 125 it never skipped a beat. I could feel the carb bowl run out of fuel, if I let off a few seconds it would get enough fuel. On level ground ground it wasn't as bad as on hills. Sometimes it would go 50 to 100 mile and only miss a few times. I stopped about 10 times on the trip when it got real bad and blew back through the tank. A few times it stopped and wouldn't run until I blew back through the line. I did find some small black particials in the flex line and glass fuel filter bowl on the carb. I made the complete trip but was a pain when it was 100 to 110 the entire trip. I called the company that makes the gas tank sealant and they never had anyone who had the liner in over 25 years. I pulled the tank and it looked like the sealant was flakeing. I am soaking it with acytone to see if I can remove it. I may wind up putting in a new tank. G.M.
