Hey everyone!

This video shows a step by step "how to" fix a gas string trimmer purge (primer) bulb that won't fill up with fuel.

This fix will work on your weed whacker, gas trimmer, whipper snipper, string line trimmer... whatever you want to call it!!! (provided the carb kit is in good shape).

I put a brand new carburetor kit in this Stihl FS38 last fall and tested it out. Everything worked as it should before I put it away. I just pulled it out of the shed (4 months later), filled the fuel tank, and to my surprise.... the primer purge bulb didn't fill like it was supposed to. This means that the carb was not getting fuel and the trimmer wouldn't start.

Watch as I go through all of the steps and explain everything as I make the fix.

It works great now!

Cheers,

Dave
