Hi new to the forum and just acquired a 1950 Farmall Cub that the previous owner couldn't get to run this year. The PO had a mechanic to install a new Zenith carb, new coil in the magneto, points, plugs, distributor cap as well as clean the gas tank.
He used it for 2 years but couldn't keep it running this year.
My son and I took the carb apart and it did have some trash in it but looked good other than that. We sprayed it with carb cleaner and put it back together.
the gas in the tank had a bright yellow tint to it and left a bright yellow residue in our white drain pan so we dumped the old fuel and rinsed the gas tank out. We did not try to remove the sediment bowl because it appears to have been repaired where it threads into the tank. Perhaps soldered or welded in place. We did remove the sediment bowl screen and spray it out with carb cleaner.
We took the plugs out and cleaned then with carb cleaner as well ad re gaped them. My compression gauge would not fit in the large holes but each cylinder appeared to have suction and compression when putting your finger in the hole and spinning the engine over.
The coil wire and #2 plug hole on the distributor cap appeared to be discolored so we used a 30cal gun cleaning brush and got it back to copper color. The coil wire didn't have an end on it, just the wire bent over, we fixed that.
We static timed the magneto and connected a lawn mower gas tank to the fuel line and the tractor started right up and ran great. WE let it get hot and adjusted the carb. WE started it several times that day and let it run.
Today we put the gas tank back on and added gas. The engine started right up and ran just a few minutes and died. It fired a few times after that but wouldn't run but a few seconds.
When we disconnected the fuel line from the carb it appeared to have good fuel flow.
i am going to hook up the lawn mower tank again tomorrow and see if it will start up and run...
Any ideas?
When we had it running the other day, we engaged the mower deck a couple of times as well as well as moved it a few feet back and forwards but didn't drive it around. WE could move the throttle from low to high and back to low and it did great without trying to stall.
the sediment bowl is staying full though it did seem like it was a little slow to fill up today when we first turned the gas on and the bowl was empty.
Thanks
Anna
