So, I do not drive my 40 too often, probably half a dozen times a year or so. I haven't driven it in 3 months so I fired her up this morning and took her for a spin. After about 2 miles she started bucking and backfiring. I took it back home and checked everything out and the fuel filter was full of crap. Cleaned the filter and she fired right up so I took her for another spin. After a few minutes the same thing happened so I repeated the cleaning. I did alot of reading and ended up putting 5 gallons of super unleaded fuel in it as well as some seafoam.There was only about 1/8 of a tank prior to adding the 5 so it should have mixed pretty well. Drove her around for a bit and she died again due to a clogged filter. Good thing the filter cartridge is serviceable. Anyways, the seafoam seems to be doing its job but was wondering how long its going to do this or how long its going to take for the clean fuel to start working. It did start to run a bit better but the filter needs cleaning after about every 5 or so miles.
