So, pretty much got my tune dialed in. My distributor was having issues and had to fix it to get my timing consistant, and I've just about got the jetting dialed in, and the accelerator pump is on. But man, I was running this thing pretty lean. When I ran the time in my sig I was only at 30-31 total timing, and have since bumped it up to 36-37 total, and have gone up 3 jet sizes on the primaries(about 6% richer) and 1 jet size on the secondaries(about 2% richer) and will be going up another jet size on the secondary again, possibly 2, since the back cylinders are still running a bit lean. I wonder how much power I was losing running that lean and with limited timing.
