I have an Allis-Chalmers CP40X gas powered forklift with a G420 engine. Looking for carburetor parts and general engine information.

Thanks

ACP40 was one model of the forklift.. the ENGINE... "G" mean gasoline.. Most were of the 153 displacement or a little larger... 420 seems like an ODD BALL number ??? G153 was a standard 4 cylinder motor that was used.

maybe the "4" is for 4 cylinder and it is a G230 ?? G 4.230 ?
