SOURCE: i have a yamaha pw 80 that starts but stays revd

Check the screw on the side of the carb in the middle, just under the slide and screw it counter clockwise.If this has no effect I suggest you check the cable adjusters to make sure you have free play on the cable.

please leave fair comment if I have helped you

thanks

SOURCE: How do I tune up

Remove and thoroughly clean the exhaust and muffler of soot/carbon buildup, test/replace the spark plug, test/replace the coil/wire assembly, and ensure that the chain is at it's proper tension.

A full bike workup includes aligning the rear wheel, checking strut/shock damping pressure.

While the plug is out, if you have a compression test unit, or can get one, test the engine's compression. It helps over time to develop a chart of compression readings from each tuneup, when it comes time to properly diagnose engine problems.
