Early Tecumseh primer bulb procedure

baymee(LehighValleyPA)April 12, 2012

I'm working on an older Tecumseh mower engine with the black primer bulb. It seems very ineffective at moving any gas. I soaked the carb and installed a new bulb, but it still doesn't force much gas into the venturi.

What's the secret to fixing these?

I had one 5 years ago that still makes me cringe! To prime, they have to build pressure in the bowl. So that means the bowl, rim and bowl seal must fit well and be corrosion free. New and new helps. Also, the air filter screws in the end have to be in place in at least some series.

All that stuff was replaced. The sticker says "Push to Prime". Notice that there is no limit on the number of pushes? :)
