1954 Ford NAA

Home Machinist · Jun 22, 2018

I own a Ford NAA tractor was running fine all week and early today but it started sputtering and idling rough. Looked it over took off the glass fuel bowl cleaned it and opened the pet cock when I noticed it fuel filled it up but really slow. Took the bowl back off turned the gas on with out it came out as should. Put bowl back on and started to trace and found flowing into the carb was at fault the elbow screen is clean but when the system is closed it trickles out if a open the pet cock on the bottom of carbuator bowl that I installed it flows out but system closed it seems like an air bouble form like a plugged vent preventing adequate fuel from flowing or stuck float in the carbuator.

Thankyou;
Travis

I always, always check my spark first.
Pull a plug wire and verify that you have a
strong bluish white spark that will jump at
least 5/16". Short or yellowish spark will
Not do. Requires No tools to pull a plug
wire and check.
You might have a fuel problem but always
check your spark first to eliminate that as
a source of it running bad.

The tractor does have really good spark blue and white thanks for the input. It would of been nice if it was just spark and not the carburator.
