Default Lawnmower that will not start

Well, folks, an update on the lawnmower. It is actually a Craftsman
edger, the one with the blade that has 3 edges (triangular shaped
blade). I cleaned it up, sandblasted the spark plug(and determined
that it is getting good fire)re-gapped it, then took off the gas tank,
took the carburetor off, sprayed it inside and out with carburetor
cleaner, put it back together, and NOTHING! I put on a spark detector
gizmo that lights up when I pull the cord, so I'm sure it is getting
spark.
The carburetor doesn't look too complicated, it is only ~3" long. It
has a butterfly valve on each end, and I sprayed through the valve, and
through the nozzle that hooks up to the gas tank. On the bottom of the
carburetor it has something that looks like a little plate, that is
attached with 4-6 little allen head bolts. I hesitate to take it off,
as I'm not sure what will pop out of there.

Any other advice as to what I can do to fire it up? I have left fresh
gas in the tank this evening, with the hopes that it might dissolve
whatever is preventing it from getting a good stream of fuel. Thanks
again, Richard


You need to move some fresh fuel thru the carb; if you run the engine
for a few minutes it might flush some of the goo out. If it were 4
cycle I would idle it with an unlit propane torch in the inlet, but
2-cycle needs lubrication. Maybe start it with gas in the plug hole and
spray a mist or fine stream in the intake to keep it running for a
minute.

A better idea is to take the carb COMPLETELY apart and clean it.
