A vacuum gauge on the intake would have told the story.

Don't own one and don't have access to one for this small of engine. It only takes about 10 minutes to rip it all apart.

Check to see that the reed valve between the carb and crankcase is sealing properly. A 2 stroke engine will not create vacuum and pull in fuel if the reeds are not flat and laying tightly against the surface when at rest.

Not to say what you should do because it's your time and money but I'm in the camp of knowing before blowing time and money. It has been suggested earlier to measure your vacuum at the carburetor to determine if you have a suspected leak. While you may already know, I just thought I'd offer another way besides using a vacuum gauge to diagnose a suspected leak issue.

The other way to search for a leak blocking off all the openings to hold low air pressure (4-6 lbs) and use the soapy water trick to pinpoint your leaks if any. It can be seals, gaskets or even a cracked or corroded case.

Whatever you do, good luck!

X2 There are good videos on YouTube describing exactly how to do the pressure test.

$16.00 on epay seems like a real bargain to me. Especially handy for checking fuel pump, lines etc. Attach to the gas line at the tank, cycle the pump and see if it holds the vacuum. Just one example.

Well, with the engine still in pieces. I went over every part and think I found the culprit....the flywheel. On the driveshaft there is a key slot for alignment to for the timing of the spark, well on the flywheel, the male end of the slot was stripped and flywheel was out of alignment.

So, now I am awaiting a new flywheel, and since I had the entire thing apart and this should have lots of life left, I ordered all new seals from top to bottom and a new piston ring for good measure, while I was in there.

I will report back, when I get it back together.

It was the flywheel, it is all back up and running. While I had the engine apart I rebuilt it all with new seals, carb, plug and piston ring to ensure I get years of use out of it. Thanks for the help!

See my post # 16 in this thread. :bash2:

Go back to post #11.....:biggrin2:


Glad the blower is all done and well! Good job!
