Review on Optimized Carburetor Upgrade for TrailMaster 🏎️ 150 XRS & TrailMaster 150 XRX Go-Karts by Brian Whitmore

I have had a TM 150 for a number of years. Never worked properly and eventually became too bothersome to play around with. After seeing a video about replacing this carburetor I gave it a try. This carb costs less than working on it. A shade tree mechanic can replace it in about 30 minutes. Started immediately and works like never before. I've had no problems and in less than a month I've logged twice as many hours as I've been using the TM 150 since it was first introduced. And you can get to the idle mixture screw, but you probably don't need it. I wish I had known about this product a few years ago.
