Wondering on people’s opinion for attached pictures? This is a 152 main in 35mm carb at about 80 deg F. One side much darker and higher up than the other side. Bike seems to skip a bit WFO so trying to see if rich or lean.

How long was it ran? Looks way lean to me, unless I am missing something.

Not long, I had enough hill to get up to 4th gear and maybe hold wide open for 5 seconds

pics stolen off the internets.
Here's what I wished my plugs looked like.
a touch richer and safer if safety is needed. :-)
too rich

Thanks, I’ll go back with 155 and do it again. May be a bit before I can get back on the bike to do it but will revert here. Any idea what or why one side seems rich and the other lean?

Sorry, not sure on that. Maybe it didn't run long enough??

Did you make sure to pull the clutch and hit the kill switch when doing the chop?
