I know this is a little OT, but there seem to be a lot of
knowledgeable small engine people in the group. *My riding mower with
a Tecumsah engine has been giving me a lot of problems, quiting, rough
running and loss of power. I cleaned air filter, changed plug, and
checked fuel filter. I found I could get it to run by using choke,
increasing the choke level as fuel level in tank went down. So it
seemed to be running very lean.


I've had to set all my small engines richer to acommodate ethanol in
the gas.
