I have a gas craftsman leaf blower/vac 32cc. it starts ok but it wont shut off. what can I try?

Many of these small blowers have an alloy key moulded into the flywheel, if this has sheared it will knock the ignition timing out, and will never run.

need to check all gas lines for holes,, only thats a pin hole to suck air

Check for spark and air filter in good shape. Make sure bulb side gasket is OK! No leaks! Good luck!

Check age of gas. Cannot be more than 30 days old.
Make sure to use fresh gas w/synthetic 2-cycle oil @ 40:1 ratio (1 gal.) Gas to 3.2 oz. Oil). Do not use old or stale oil/gas mixture. Always use the proper oil/gas mix. If you do not, your engine will suffer rapid, permanent damage.May need to clean or replace carburetor.

Most of these mix at 50 to 1. 500ml of oil to 5 gallons of gasoline should do it. If you don't feel comfortable with this mixture try 40 to 1.

IF it says 4 CYCLE then it uses regular gas.(87-89 octane unleaded) Another sign to prove it's 4 cycle it should have a crankcase you keep filled with oil.

most likely the air filter is clogged, take it out blow it out or spray water through it and allow it to dry completely.

alterinavely, just pouring a small amount of gas onto the filter should make it work, i would do that even if you do clean it properly.

this method works for cars too!

your problem is inside the carburator.there is a small screen inside that needs to be cleaned out.take the single screw from one side of carb.there is a small screen in side.carefully take an air hose and blow it out.do not blow to hard or the screen will blow out.once it's clean the unit will start right up.hope this helped,let me know.................................

try replacing the spark plug.
