Hi List,
A little while ago I sent out a question on how to adjust the valves on a
Briggs & Stratton.
I couldn't imagine how a valve could stretch and be bigger than it was
when installed.
Thanks to all who responded. It is much appreciated.
Sometimes my thinking just defy's all logic. When I finally got around
to taking the valve out of the engine, I realized that the valve face had
simply worn away. (Stupid me !) Thus, making the valve seem too long
and not seating. Feeling that I "had nothing to lose", I figured I need
to reface the valve.
I stuck it in the drill press to spin it and used a file to reface the
valve. Then ground the end of the stem to fit the valve in the engine
with a .007 clearance. Looking at the work I did, I was starting to
feel like a damn machinist !!! I actually felt good about what I did !
After installing the valve and putting the little engine back together -
I gave it a little squirt of gasoline and pulled the rope - - - IT
STARTED !! and ran for about 2 seconds.
Then I tried again and the engine seized up. Damn !!! What happened ???
It seemed that something got into the cylinder (or so I thought). Upon
taking the piston out I found that there was a bunch of aluminum shavings
between the rings and the piston groves. I guess the rings were "frozen"
to the piston and now I have a scored cylinder wall.
CAUTION - - Never take for granted the condition of things you cannot
see.
I still have hope for the little engine. I've cleaned up the cylinder
and feel it just might be runable in this condition. If the cylinder
wall scores again, then I guess it will be JUNK.
Right now I'm soaking the carburetor parts in denatured alcohol so
dissolve the varnish.
