On a full drag ported cub...geez, I sure hope not Wes..

 

If you're running a single carb, you're probably close.

Duals, I'd say you're beyond safely rich....WAY rich, especially on the pilot.

sorry ya duals pj 34 when i did plug run today they where black in color (aka) rich

and the bike boggs on top any idea what to bring main & pilot down to thank for all the help +)

52 pilot, 150 mains

 

needle most likely mid clip or 4th dek needle i used

 

depending on what needle you have. makes a difference.

 

this is what i ran at 1000ft

 

plugs looked great.

this was with shearers and pods. you might have to adjust your mains a bit. not too much my guess.

I'm running perfect w/ 172 mains, 60 pilots, DEK needle 3rd clip w/ a 4mil, shearers, mx port....I find the PJ's need richer settings then the PWK's... Does it start easy when cold? Warm? Do you need the choke? I'd try some 175 mains and do another plug check.

I was going to post the same topic this morning , i am running my pj 34s on my 421 cub and wondering what i should be at , right now its at 52 pilots 172 mains and it is somewhat lean on the plug check. i was thinking of upping the main today ,and i have to choke it with the pilots that it has

 

also i have 35 air strikers what carbs do you guys like better , i feel the 34s give a lot more grunt on the bottom and the same on top than the 35s

I find they are both great carbs, they claim the 34's are better for throttle response, but I don't see it....if they are, it is very minimal..
