Hey guys, I am working on a 1954 Allis Chalmers G garden tractor for a friend. I have been working on this thing for a few months now, and I am starting to lose hope. My problem: At the first start of the day, the tractor will run fine for 3-4 minutes. Once it warms up a bit, it dies. It acts like it is running out of gas. It will restart and run for a few seconds but die once again. When it starts to die, it makes a weird metal scraping noise from the crankcase (I think). Things I have replaced: points, condenser, fuel tank, fuel lines, fuel sediment bowl, wiring harness, main on/off switch, and the carburetor. Things I have tried: rebuilt the old carburetor, reset the timing, and used new fuel without the 10% ethanol. The timing on this little engine is a bit confusing. Some say the number one cylinder is close to the radiator; others say it is close to the timing gears/crank pulley. It ran fine when I used the cylinder closest to the radiator for number one, but I am truly not sure which end number one is located. Is the number one cylinder located on the end with the fan belt or nearest the tractor seat? Thanks for ANY and all help.  |

| Thank you! I had it wired backwards then. It ran fine but not for long. |
