So once I plug chop, if it’s rich and I need to go down a size or two? Does the pilot also go down the same? Quote Link to comment Share on other sites More sharing options...

And I’m not sure what pilots are in mine off the top of my head. If it idles good then keep what’s in it Quote Link to comment Share on other sites More sharing options...

Bigscott260 Posted April 29, 2023 Report Share Posted April 29, 2023 I’m running 155/48, the needle in second position. Still have a low-mid bog though. can’t tell if pilot is rich or lean or if the needle is rich or lean. Trial and error is all. OEM engine added T5’s, cool head w/21cc domes, 100 octane LL, 28mm PWK’s with UNI pods, Vito’s intake and reeds. Quote Link to comment Share on other sites More sharing options...
