[AT] OT: success repairing small 2 cycle engine

[K7jdj at aol.com]

Hello everyone,
 
List is slow so I though I would tell of a success story on getting a small 
 #%&*@  2 cycle engine to run.
This is an engine on an old "Wacker" soil compactor.  I bought it off  
Craigslist a few years ago.  I got it to run but never very good.   Besides 
difficulty starting and running the engine, the automatic clutch is not  
disengaging at low speed.  The Wacker jumps up and down to compact soil.  This 
action really subjects the engine to excessive vibration/motion. (Not  great for 
the operator either). The engine uses a Tillotson carburetor that  
incorporates an internal pulsing fuel pump (provided by a connection to the  
crankcase).  After removing, cleaning and installing all new gaskets and  
diaphragms the engine ran better for a while but then got worse and finally the  
engine would only run on starting fluid.  The rebuild kit came with 2 welch  
plugs that I was reluctant to use as it involved drilling the old ones to  
remove.  I finally drilled them out and found a screen in the high speed  jet 
area that was plugged.
 
I don't understand what the debris consisted of, or how it got past the  
fuel filter and main internal carburetor screen located ahead of the float  
seat.  The Whacker now starts and runs good I just need to work on the  clutch.
