If you have been using cheap gas, try a tank of "top tier" gasoline like
Chevron, Texaco or Shell. (I think BP is top tier also, but we don't have
that here.) Alternatively, you can add a bottle of fuel injector cleaner
like Techron, but my experience is that a tank of good gas is as effective
as injector cleaner.
I don't know what to think about the A/C output varying... are you saying
the air flow rises and falls? And does this happen at all speeds or only at
air output does rise n fall. bought a recharge kit and gauge says my
freon level was fine to start with.ill try the goos gas theory, i do
use regular from exxon, maybe a higher octane will help....worth a shot
You may be having the compressor/clutch binding a bit ..
IE: the compressor is requiring a lot more energy to turn
than is normal. With a small engine, a tight compressor
can almost kill the engine if it's bad enough..
Once one locks up, the belt will squeal, and sometimes
will add enough drag to kill the engine if at idle.
Not saying this is the problem, but something to consider
if you have zero problems with the A/C off, but turning it
on feels like it wants to kill the engine.
The blower speed should not vary any more than in relation
to the voltage. But it will be normal to notice some reduction
of blower speed if the engine is close to stalling. This is
due to the lower output from the alternator during those
short times. But you shouldn't see anything really drastic,
or any on/off sputtering of the blower.
