O.K. My report back. Carb that was not drawing is now on the charts. I think the linkage had it positioned with throttle plate totally closed. The backfiring issue, however, Is NOT doing just fine thank you.
I tried the starting spray and can get no localized area where the rpm rises. So, do you think it would be better to continue trying to localize the fault OR just tear the top off and start over making sure the gaskets are sealing??? I'm leaning toward dismantling the top to start over with new gaskets on the manifold to heads. Thanks Jon
