Carb icing on 1600 gas

1 - Make sure the carburetor is properly adjusted for warm, dry weather operation - especially the idle mixture adj.

2 - Before using the tractor, start it and run at fast idle (1,200 RPM) for 5 minutes or, or until the carb is nicely frosted outside. Now shut it off and wait about 5 minutes until heat soaks from the exhaust manifold and melts the frost. (If there's any breeze, position the tractor so the manifold side is out of the wind.) After the frost is gone, tractor should start/run fine.

3 - Until the engine is fully warmed up, run the tractor in a lower gear/higher RPM than normal - especially if you're working a light load.

4 - Use fresh gas! (Not gas that's been sitting around for 6 months...) I've found a bottle or two of dry gas in each tank of gas helps too.
