Unconventional Carburetor Fix on a Troy-Bilt Trimmer/Brush Cutter + Routing New Fuel Lines

[@MrRmh3481]

Did you notice the blue green colored spring on the Idle Speed screw? If you see a bunch of those springs on a carb, its an indication that unit was a refurb. Great job on catching the throttle clip and getting it running again! The early upside down engines (spark plug on bottom) came from the Lawn Boy Brush Cutter design.

I hadn't noticed the color on the spring until you said that, great catch! I knew the upside down engines were older designs, but not that they originated with Lawn Boy. Can't say I've actually seen a Lawn Boy brush cutter yet (or any handheld LawnBoy branded equipment for that matter), but I do have a mid-2000s 32cc Craftsman of this same engine design made by Poulan that I still use personally. Thanks for sharing all that info!

If you take a small steel wire you can run thru the whole in the tank and out the filler neck and you won't have to remove the tank. Nip a piece off the end of the line like from opposite tip down about 1/4in to otherside and push wire thru the line and pull back up or down thru the tank

Nice tip! I’ll have to give that a shot next time I work on one of these style trimmers

Lol yeah I guess if you just look at the line count it’s more of a complicated routing situation than spaghetti
