I got my 59 Vette with a 350 out of 2 year storage. After minor tune-up it seems to run fine, but it is running cold (130-140). I checked the dash-gauge with a radiator cap with a built-in gauge...same reading. While I haven't taken it on a long trip it seems to be getting much worse gas-mileage than before it went into storage. While I don't believe anything was done to the carb while it was in storage, could both problems be related to it running much too rich?
