Craftsman blower losing power

I have a 2-cycle Craftsman leaf blower that is a little over a year old. I just replaced the ignition module and fuel filter, cleaned the air filter, and took the carb apart and cleaned it (all in response to the fact that it wasn't running at all this spring). I got it running again (ignition module), but it makes a weird "clicking" noise and loses power when I throttle up.

Any ideas what could be causing this?

 

The clicking noise is hard to imagine. Any chance the ignition module is too close to the flywheel?

 

It almost sounds like a stick caught in the impeller. It only happens when I hit the throttle. It idles nicely. Would a noise caused by misaligned ignition module only manifest itself under power? I will tear it apart and check either way. What's the next thing to check just in case?

 

If the crankshaft bearings are worn enough to let the shaft move, then it would do it more-so under acceleration as the crankshaft has increased torque applied. The loss of power could be related, or it might just need the high speed mixture screw backed out a tad.

 

This thread has been dead for awhile, but I am still having issues. The drought in the Midwest has left me with little cause to use the blower (grass that doesn't mow doesn't have to be cut and the drive and sidewalks don't need to be cleaned up afterwards). I had it out and it fires up fine, it is a little hesitant to go when I gun it at first, but eventually responds pretty well. After running for about 3-5 minutes, the clicking/grinding becomes more pronounced and power is lost. It doesn't matter if I back off the throttle and then rev back up or even stop for a few minutes and fire it up again. It seems to only abate if I let it cool down completely and restart. Does this help point it towards anything specific or am I still playing a guessing game? Thanks.

 

Hard to say. These are prone to the cylinder bolts backing out so maybe your cylinder is getting loose?
