Valve Float
Hi Guy's
Does any one have any tell tale signs of floating the valves.
Everything was working good before I changed my DP from an older 21/2 meese to a 3 inch and electric cut out. My btm end power is good all my scanmaster readings are fine. butt, at over 3500-4000 rpm or 3/4 to WOT its sounds terrible especially with the dump open!
It's missing and stumbling best I can describe it. I'm guessing valve float because everything was good before. My valve springs are still stock.
Thanks for any Input all is welcome. btw plugs are good, gapped to .032 and wires and pack are good. I did a search but no definite answers.
