Dirt/debris in the idle circuit, take carb apart and blow out all the jets. Check float level and reassemble carb.

However, ever once in a while you can get lucky and clear it by revving it up and capping your hand over the carb inlet , choking it, and it may suck the trash on through. Good Luck.

Check for vacuum leak. Carb base and intake manifold. With engine running....Spray brake cleaner around suspected leak areas, (but not around carb intake.) If a change in RPMs, you have found your leak.

Also check for dirty and/or improper gap on spark plugs
