And just to be sure, I went to size 92 jets this afternoon with no improvement.Because I tried bigger jets and they didn't make any difference! And if you saw, I was told they are probably too large.
I'm thinking of a way, not to fix it but just as a test, to stick some fine wire into the air bleeds to restrict the flow. I'll solder all the wires together and secure them so they can't get sucked inside. Again this is not a FIX, it's just a TEST.
Even with it running so lean, either I forgot how it ran before, or it's picked up some horses compared to using 40+- year old carbs. It is 50 more cfm.
