Other surging culprits?

Rivets and WhyZed, thanks for the advice. I've been reading and intend to work on it some soon. I've just been busy lately. I do realize I need to pull the carb, but I honestly hate pulling the Duraforce carb. I know, I'll make it happen by Sunday. No, I don't intend to drill any jets yet.

Rivets, speaking of punching jets, I haven't done that yet, but my curiosity is up. I imagine I may eventually just for the sheer fun of it. I believe you about not wanting to do it if I haven't before. I guess that's the reason I'd play around with the notion. Of course, I'd have a couple of new jets on hand too. So, having said that, perhaps you could pass some of that knowledge around on the subject.

Very simply put, punching a jet means to increase it's size by less than .001 at a time. This is done using micro drills and a Pin vice drill. Doing this will allow more fuel to enter the different passage ways in the carb and produce a richer mixture. Doing it wrong will result in carbon buildup in the cylinder, plugs carbon fouling, back firing in the muffler, excess fuel consumption, etc.
