Hello. We have a 1947 WC Allis Chalmers that will not start. We have installed a new condenser, new spark plugs, fresh gas, and rebuilt the carburetor. The engine turns over but will not fire. The timing has been checked, and there is spark being generated by the spark plugs. We are thinking that there might be a stuck valve.

The tractor has been stored inside an insulated garage, but has not been run in about the last 3 year.

Any help that can be provided to us would be greatly appreciated.

Sincerely,

Chuck and Mike

You see the SPARK turing by hand or the starter ? Turn by HAND and make sure you get the FIRE at the TDC Top Dead Center Mark.. The MAG will advance to FIRE after startup.

Look at the plugs.. If they are dry, you might try putting a spoon full of gas into each hole and then installing the plugs.. If you have good SPARK, have you tried starting fluid sprayed at the air cleaner ? If you get a POP - POP then you know you have spark... If it actually will RUN on the fluid, then you know the timing is close to correct.

Rebuilt carb does not guarantee you have gas flow into the bowl and getting into the intake.
