I have an old early 80's MTD 18/42 that needs some work. Its not a good mtd farm king or anything like that, but just an old lawn tractor. Its heavy duty with a peerless 2300 transmission and has 5lug 23" tires. It has an 18hp Briggs Opposed Twin that is way over sized for this thing but thats what i need.
I am turning this into a "mudding mower" meaning pulley swaps, atv tires, lights, bumpers, straightpipes, gas pedal and better steering. To me, i see this thing not having any other use other than tooting around and using it as a puller.
The question however is about the engine. I cannot seem to get this thing running good!
I took the heads off and cleaned the gunk, took the intake manifold off and cleaned it as well as the carb and EVERYTHING on the inside is SPOTLESS but it still wont run good. It starts and idles but its rough and gradually idles so low to where it shuts off within 2 minutes. when i throttle up with the gas pedal it spits sputters and occasionally backfires. ive tried to adjust the carb and it seems to help but it still acts up.....
I need help. bad. Any advice would be greatly appreciated!
PS, ill post pictures when i get home.
