Hi, some very helpful tips on the forum. Here's my issue, I read that these 2+2's weren't made to idle very well. Not so, I have owned it for 2 years now and have gone through the manual a few times. It always idled a bit rough, but I performed the lync and sync, and she purrs like a kitten. I didn't realize it could idle down so low without even a sputter. Fuel pump, filter and all new gas lines including primer bulb last year. My problem now is when at cruising speeds, the motor tends to loose rpm and bog and then come back up. It almost seems as if it's throttling back and I think that I can hear the butterflys shuttering? I haven't checked the timing yet, but thought because it's running so smooth this wasn't an issue. Going to take another look at it today to see if I missed something, but just wondering if anyone else has had the same problem. Thanks!
