How to tune a small engine carburetor with governor

Learn what the screws on your carburetor are for and how to adjust them. When the engine is running lean, the governor will make the rpm’s rollercoaster up and down. When the engine is running too rich, it will skip a lot and produce black smoke from the exhaust. I didn’t mention this in the video, but perform these adjustments after the motor has completely warmed up for best results.

Please comment with any tips you may have if I have missed anything, and thanks for watching!

SURGING ENGINE: This is a dirty carb, not the governor.

99% of all snowblowers, tillers, generators, log splitters, pressure washers and other equipment are designed to run safely run @ 3600 rpm max.

Mowers engines are designed and can easily handle a max of 3600rpm…However lawnmower blade speeds are goverment regulated and since the blade is directly connected to the engine they are sometimes limited to speeds closer to 3200rpm. Check your mower mfg for specs. Some mower manufactures lower the rpm only to reduce noise from the engine.
