Craftsman blower 25cc leaking carb

I have replaced the primer bulb and fuel lines on this blower. I cleaned the carb at the same time by spraying with carb cleaner and blowing out any orifice with compressed air. I did disassemble the 'diaphragm' at the base of the carb. Now after assembly, when the primer bulb is pressed, gas leaks from this area. The blower will now start either. Did I do damage or will a new 'diaphragm' gasket fix my issue?
All comments, criticisms, or suggestions welcome....

Edit: This post is about the leaf blower, not the Ryobi trimmer. That's another issue...

I've read that compressed air is a no-no on the 2 cycle carbs like walbros. There is a check valve in the main jet that be ruined.

I think they say the force of the spray cleaner is enough to clean these.. Any time I take these little carbs apart, I always use new kits.. If the primer & lines are rotton, so are the diaghragms.. Find who made your carb & get a kit for it. The manufactures have excellent manuals on their websites.. Pay close attention to the order the gaskets & diaghragms go together & you should be fine..

Intermittent Engine Dying?

P

Pilot Dane on Jul 28, 2011

I have a Yard Man/MTD model 11B-106C401 with your usual side valve engine. [URL="http://www.oscar-wilson.com/MANUALS/BRIGGS/12V800.PDF"]Here[/URL] is the break down for the engine. The engine starts easy and runs like a champ but occasionally dies when mowing. It seemed temperature related so I've replaced the coil but the problem has not changed. It mows 15 minutes and then dies and will not even try to fire until it's cooled for 10-15 minutes then will run for 5 minutes and dies and will not start unless it's cooled for 10 or 15. When it dies it sputters for a few seconds and then quits and will not try to fire until it's cooled. I'll pop out at lunch and grab another spark plug to try but I'm not confident that will help. Right now I've had the engine running no load for half and hour (it's still running) and it still has not died. I've shaken and jostled the mower and it's still runs smooth but I assume it's not getting hot enough without a load. Dare I invest in another coil for this 10+ year old cheapie mower? Am I missing something?Read More
