I am working on one now. Customer said "it doesn't run". Ok. So, after oil/spark plug/air filter replacement...it didn't have any gas getting to the carb. Took off the bowl, and on this 2005 lawnmower, the inside of ALL of the carb was covered with a white/chalky film. Looked like tiny rust barnacles over ANY metal surface available. Silty white stuff in bowl. Blasted it all w/carb cleaner. Still couldn't get primer to work, but after I sprayed a bit o' starter in the cylinder, it started well & kept running. Until I let the bar down. Needs a new carb. Will see what the customer wants.

Tractor wont start


For a small gas engine than won't start, think FAST -- Fuel, Air, Spark, Timing. You've replaced the filters and spark plugs and squirted in some starter fluid, eliminating the simple common fuel, air, and spark problems -- but I because of the backfiring I think your problem is in the timing -- like a sticking valve. Probably more than you want to tackle at home, but might not be as expensive as an engine replacement. Take it to a good small engine mechanic -- best bet is a lawn equipment shop that has been around many years. Drive a little farther to get to one if necessary.

Backfires through the air cleaner


This usually means a bent or sheared key in the flywheel. Remove the shroud exposing the flywheel buy a 6" flywheel puller and remove the nut for the flywheel and attach the three jaw puller remove the flywheel and replace the flywheel key. The only other thing that causes this popping through the carb is a burnt intake valve this is a job for a lawn mower shop.

Engins starts and runs when mowing will backfire and stall.


I am not sure what time of lawn mower this is, but if the blade is directly tied to the motor, usually the belt will just slip if not, but if this is directly connected to motor, it might have jumped timing. If this is not the case, inspect under the mower deck, and determine if there is something jamming the blades against the deck or if their is something bound around the blade, this can cause more strain on the motor, which could result in the symptoms your experiencing.

I started my craftsman 21hp 42in deck today it had a rough idle with backfire and when engade mower it seemed to not have enough power


Backfiring is a sign of too rich on gas and not enough air. Not enough gas will cause the mower to bog down when blades are engaged as it isn't powerful enough to run the motor AND turn the blades. Check your carb and see if you need to clean it and replace diaphgram. Sounds a lot like a carb problem.
