I haven't had the top off the carb. The squirrel condoms look good, I won't say with 100% certainty that the rubbers are on correctly but I am pretty meticulous. They were only off once before to rejet. Aside from what I stated above, I haven't tried anything else..... I am at work right now trying to come up with a list of things to check so that I have some kind of game plan at 3:30 when I get out. I though about trying that smoke test to see if the right side is pulling vacuum, and I had a friend mention a compression test.
