I just ran a few tanks of few through my LST2, it was running pretty good. About 230 with the body off and maybe 260 with the body on. It gets hotter as the tank drains. Is this normal? Also, I ran last night and it seemed set fine but then today I had to lean it out alot more just to get it back to the 220 range or so. Is it normal to have to tune it every day? I live in south florida, the temperature does not change that much day to day.
