Just curious what part of the country everyone is from.
Me, I'm here in Vegas.
Hey SIrhino. I don't really do any custom carb tuning or really claim to have any more knowledge about same than anyone else. I simply try to articulate what my understanding is of a given problem all the while knowing that I might not be correct. The only training I have ever received has simply been under a shade tree with a shop manual in hand and beyond that, seat of the pants analysis.
If you have a specific problem, I would certainly be happy to offer my opinion. Simply realize that it may take some trial and error to get it right.
Given the info that you provide, if you have an RAIS Power Tube style setp with a unifilter and stock jetting, you are already running lean and a 2 inch tip will amplify that condition even more.
