My plugs look alot like yours, I don't have enough room to do a proper plug chop without running through cow shit . I need to haul it somewhere I can open it up. I'm running 172 mains,52 pilot and cel mid clip in 39pwks. This is a drag ported cub though, Kevin at HJR said that the 52 is the proper pilot and was adamate about not changing it or the needle, clip position and mains can be changed. It may be a little rich but does not bog or hesitate and flat out screams, this may just be something with the drag setup idk. I don't want to change too much but don't want to carbon up stuff either.
