Why does your leaf blower die when the choke is turned off?

Answer 1

There are several reasons a leaf blower could be stalling when the choke is turned off. All of the reasons have to do with the engine not getting enough fuel. If the gas in the tank is older than 15-30 days old it is probably stale. Dump it out of the tank and run the engine until it stalls and will not restart. Now add fresh fuel and see if the problem persists. If you are still having problems the carburetor could be clogged. The easiest way to fix it is to dump the gas back into the can and add 1/2 of an ounce (15ML) of Royal Purple Maxclean to 1 gallon of gas in a gas can. Before adding it to the leaf blower start the engine and run it until it stalls and will not restart. Now fill the tank with the 1 gallon of gas with the 1/2 of an ounce of Royal Purple Maxclean in it. Start the engine and run it on choke revving it a lot until it starts running rough. Then turn the choke down until it runs well. Repeat running it and turning the choke down until it runs well until it runs well with the choke off. It may take a few runs to fix it. 95% of the time the Maxclean in the gas will clean it out and make it run well without the choke on. If that does not work the carburetor will need to be rebuilt as the rubber diaphragms dry out and crack over time. There are many of videos on YouTube on rebuilding leaf blower carburetors. I hope this helps.
