need help have big amount of snow and the snowblower is not running right. it is a 5hp craftsman blower about 12 years old and it start fine but as soon as it get under load it start to bog down and almost die if I don't let off. it has run fine in the past un till this year. I have allways drained the fuel every season. I have even tried fresh fuel. don't know what to try next.

Usually it's varnish build up if the fuel system / fuel has been kept clean.

That being the case I would put Sea Foam in it. It will probably clean it up. Usually you'll see a difference within an hour of running.

You still need clean fuel, good venting on the cap, good lines to the carb and a good plug.

You can get Sea Foam at Walmart and most auto parts stores.

I agree with marbobj. Try Seafoam first.

I noticed fuel leaking from the fuel bowl and took it off and the gasket fell of in about 6 different pieces wood that have anything too do with it running wrong. am going to wal-mart today and going to try the seafoam also.

No, but having to make an assumption that the fuel leaking was more of a slopping in the bowl due to movement of the blower, as opposed to an overly full float bowl.

Of course the gasket should be replaced.

tried the seafoam and run it about three hours and still does the same thing. a friend said it might be the governor. I think i will remove the carb and take it apart and clean it that way.

Post the engine # and make / serial number so that a qualified Pro here can tell you which carb you have and what rebuild kit is needed.

help

Just purchased a 5/20 craftsman. It will not start. I have a good spark. good gas flow to carb etc. I lossen the high idle jet at the bottom of the bowl and no gas comes out. If I remive the jet, should i not have gas coming out.
Seems like the engine has good compression. The choke was jammed shut at the carb so I had to loosen up throttle and choke with intake spray which worked fine.

What can I check next. Seems like the spark plug is not wet. Seems like no gas geting to plug.

The blower does have a ket start. I get the spark regardless if key is on or off. The ignition was off the machine when i purchased. i just hooked the one wire up to the one wire i found stranded and figured all should be good to go.

ANyone have any good ideas on where to go next? Do i need to pop thr carb off and do a good cleaning etc?

cured my problem bought a 6.5 hp greyhound engine from tool harbour freight. it will throw snow farther than the original motor and it starts really easy. it started on the first pull and it was 6 degrees out. all the pulleys fit right on it and the motor mount hole were exactly the same. only took about 20 minutes to swap.
