added some fuel to get it to run in gear, took it to the gas station to fill it back up and noticed it was way rich at cruising rpm to and from the station. Multiplied the 1200+ rpm blocks on the map by .75 to reduce the amount of fuel in it and quick burn and drove it home, BLMs were in the 135 range, o2 voltage bounced between .350 and .550 on the trip home last Sat. It has set without being touched since its single digits here, I decided to put a battery tender on it while it sits and I decided to start it. Turned over a few times then fired right up without an issue, I must not be messing it up to bad. Headed on vacation for a week will be back tuning it once I get back, hopefully warmer also.
