Allis Chalmer Big Ten. I got Spark Gas butNo Start

Message Topic Search Topic Options Post Reply Create New Topic Printable Version Translate Topic

   Sparking blue. Brand new plug.

New fuel line and fuel filter.

Gas is running through.

It cranks but won’t turn over.

Trying to adjust air mixture screw and floater needle valve as well as trying to manually pump the gas above the carburetor…

Had it almost start a few times but can’t quite find the right adjustments on those two and had a friend recommend taking the head off and grind the valve cause he thinks there’s not enough air compression in the motor…

What does all the experts here think? Trying to remodel this but before anything I wanna get it to start run and purrr!
