Craftsman gas leafblower

After starting and running for a few minutes will stall when putting throttle to max and choke to minimum. Hi, I have a craftsman backpack blower model # 316.79499. I have a problem of the engine wanting to die when full throttle also, it seems as long as the gas tank is full it will run great, as soon as it gets down to about 3/4 full it starts to bog out. This happens even when the engine is fully warm. Any Ideas?
Thanks,
Karl

I just worked on my craftsman leaf blower that would only run at half choke. I tried cleaning the carb and also cleaned the exhaust port. Didn't help. Then i took the cover off and noticed that one of the head gasket bolts was loose. Tightened the head gasket bolts and then it ran fine. Must have been sucking some air.

Hey Karl,

To me this sounds like its getting too much fuel after it has been warmed up so either there is too much gas flow to the unit or there is not enough. check your primer bulb once this happens if there is a full bulb when it shuts down chances are its getting too much gas, if its empty then its not getting enough and your fuel filter could be starting to plug up or is not in the tank properly.

    also make sure you have good spark on the unit as well. if the plug has been changed then make sure its gaping is correct or if its a old plug its always good to change it if need be.

All small engines take a few minutes to warm up...especially so as they age.

You have to learn to 'feather' the throttle to very, very slowly increase the gas.

After it is warmed up, you are much more likely able to rev it up...release, etc.

I've had many over the years, and this is a very common problem...that you learn how to handle.

Start snow blower runs for 3 min. and starts to over heat checked oil its ok then stats to shut down like its not geting oil


Why do you say its over heating .Runs for 3 minutes the oil is OK .
Do you understand how the choke works .
bacsicly you prime the mechine in cold condutions 3-4 pumps choke to max throttle at 3 /1/4 .
Start backing off the choke after 3-to4 mins .
The choke shuts the fresh flow down to the engine in cold condutions ware it needs more fuel then air to run.
When the engine starts to get hot it can't run with out fresh air to mix with the gas it won't run anymore because there is to much gas and not enough air
Its simple fool prof will work everytime if you adjust it right

32 cc weedwaker mod#358791072 starts fine, will run at idel for warm up, dies when you give it gas or start it with choke in run position.


If you only have one jet screw adjust the "H" Jet screw on the carb. Make minor adjustments of less than 1/8th turn. Test engine acceleration after each adjustment.
If you have 2 Jet screws "L" and "H" only adjust the "L" screw.
On the 2 jet carb the "H" screw is adjusted for ideal top engine RPM / Max speed.
The goal is to elimate engine hesitation / stall as you grip the throttle quickly by adjusting the "L" jet screw..

Briggs and Straton 8 hp, craftsman snowblower stalls


Sounds like you coil is over heating after running a few minutes. The windings are seperating, then when it sools they make contact again. Try replacing the coil.

Craftsman Weed Eater only runs on choke (not at all now!)


Check the mounting screws holding the carburettor and the plate behiend the carb, they often become loose, also the gaskets, they might need renewing. Your carb. could need cleaning and new diaphrams. stephen.

Craftsman 32cc Trimmer Runs with choke at idle, then stalls


Sounds like somewhere you have a air leak. Most likely it's somewhere near the carburetor intake or maybe the carb itself. Could be a line from the primer if it has one and i do believe it should that could be leaking or loose. Good luck.
