Yeah, I may just be patient and see what people think of the LRP .30 before I do anything, and then decide between that and a Picco. I'd still like to get my K4.6 working right, even if I know I'll ultimately replace it. It's become a battle for pride at this point!
As for the Picco, if sealing the carb is all it needs, I feel pretty confident I can handle that after sealing the carb, the backplate, and now dealing with front bearing issues on my K4.6! Anything has to be better than what I have!
