Bypassing the enricher circuit.
Speaking of Enricher, in an effort to ensure that was fully close, I put a bit of a tougher spring in it about 4 months ago. And I haven't used the enricher in more than 8 months. I verified that it is not pulled out as well.Bypassing the enricher circuit.
So if the enricher circuit is closed (seemingly) is there something I'm missing that may have inadvertently changed? One small item; when I first took the shim out and re-assembled I noticed my throttle cable at carburetor (where there is a lock nut on each side of a metal holder) had popped off the holder. The throttle was reacting poorly and I realized the oops and replace it and tightened it up as best I could. That's the only other thing that got messed with other than taking the shim out and putting the shim back in. For many months my AF adjusted fine with my 58 Pilot jet.That was the meaning.
Yup, that seems to be fine. I really didn't alter it's adjustment. Put it back the way it was. Still would like to know what has altered the AF setting pushing it toward fully lean. And why the RPMs aren't going up at all as I go 1 to 3 turns CCW.Make sure your throttle turns about 1/8 inch it needs some slop to make sure butterfly closes all the way.
I haven't noticed a dip in MPG, and I haven't messed with the Air cut off valve, but I will look at it. That would be a kick in the head if suddenly out of nowhere, some other part had an issue.Air cut off valve could need cleaning if you're mpg has gone down it is a sign.
It is opperated by vacuum forward side of carb.
