Carburetor chipped
« on: February 21, 2017, 10:30:14 pm »
I was blasting out a carburetor with an air compressor today and a couple little pieces of it chipped out. Unfortunately I didn't get to see the Carb before it went into the sonic cleaner. Could water corrosion have weakened the metal?

Could be.  Probably more so vibration. 

Be careful with too much air.  Some Walbro carbs use a high speed 'nozzle' which inside has a tiny cap and check valve.  If they go flying chances of you finding them is pretty low.  What then becomes worse is Walbro wont sell a replacement nozzle...  HDA-268 comes to mind.

Some times you have to watch that air pressure .I unwittingly blew the check valve from a Tecumseh carb on a Power Products AH -58 engine and never found it .That gear drive saw at the moment is another one of my many projects awaiting  parts resting in a box on a shelf until that time comes .They will in time,always have in the past.

That damned saw had sat under a pine tree near Meadville Pa for what must have been years and given to me .What made it die on the vine was a disconnected wire going  to the ignition points .I stripped it right down to the bones and made a new reed valve and reassembled it .The Fairbanks-Morse type starter needed  some parts so I thought it was a grand plan to wind it up with a drill motor on the crankshaft nut .I wasn't such a good idea .Spun the nut off and the flywheel orbited my garage about two times before it stopped and just missed my wifes Cadillac.Could have turned out badly .
