I visited Rick yesterday, and he had a 5 Hp Craftsman weedtrimmer which would be very useful to clear the brush around his shed - to help with the repair of the shed.

After disassembly, the carburetor is very corroded, which probably locked it in the open position, which would have caused fuel to leak all over it.

Need to research to see if it is cost-effective to replace the carburetor, or the engine, or maybe the whole device.

(Didn't see a replacement engine.)

Ebay has aftermarket for about $13

A new Craftsman High Wheel 22-inch trimmer is about $399.

Ordered carburetor, spark plug and air filter on ebay for about $30 including same day shipping. 7/17/2016

Installed carburetor, engine ran for about 2 minutes OK, then started pulsing. Not sure if gas is bad, or if the governor is not running correctly. Will check sparkplug. 7/19/2016

Read on line that the governor needs to be adjusted. So leaned arm clockwise - Pulsing stopped but runs at lower RPM. Rick said the pulsing is normal. 7/19/2016 6:49 p.m.

Adjusted the arm to be a bit counter-clockwise, and the engine ran properly. Cut half of the back yard in about 20 minutes. Pull start needs to be replaced though. Was able to start it, then remove starter to do the work. 7/20/2016 11:46 a.m.
