First, I only use non-ethanol gas, the loping eased considerably,would someone have made carb adjustments to compensate for something I haven't found yet?
Sprayed carb inside and out loping eased even more.
Checked, cleaned plugs, loping eased more and now the idle is too high i.e. as if it were on 1/4 throttle.
Checked compression...good @ 120-125, doesn't hold it long, few seconds
Tinkering with idle adjustment today.
BTW, this is a B&S model 422437 type 1209
Loping cured...someone had the idle mixture fiddled with, I suppose, in their opinion, to cure another problem.
Now it purrs, eh, such as a B&S does, definitely not a Onan.
