I have been using this electric start generator for about 2 years on
and off, typically once a month. Last time I tried to start it it
sounded like the battery was close to dead, but it was not. It was
very hard to turn. In fact, using the rope it was a killer to get it
started an I managed to do so only a few times. It turns well with the
spark plug removed but very hard with it attached. Too much
compression to turn. I read somewhere that there is a decompression
valve deep in the crankcase. Could it be anything else. Once it runs,
it runs good. But by now, its almost impossible to start.


Batteries have to be tested like a cars battery for load to know its
good. What is voltage, try jumping it.



Jumping won't do it. Also, I cannot start it with the pull-start. The
resistance is so high that it will not pull unless I relife the
compression by taking the spark plug out.



Can be caused by "hydraulic lock" if raw fuel is getting into the
cylinder (aka flooding) during periods of shutdown.
