Small Engine Troubleshooting Problems? Ask a Mechanic Now.
Was the float bowl full of fuel? If you put fuel direct into the spark plug hole, re-install spark plug will engine run for a few seconds? What is application? Snow blower or mower? Model number of application
Did you remove the needle valve? Is it needle with rubber tip or an all metal needle?
Do you have engine model number? Example(###) ###-####B1??? Here is a basic carburetor, it can be cleaned, the main jet is the usual problem, or the needle valve and float stuck.
Looks like this?
It can be cleaned, but a new carburetor is easier option, but either way, you are going to have to find the model number! Did the link I sent look like yours?
