Hi,I have a question for anybody that may be firmilure with the tower hobbies st-15. I just recently got a temp gun and after a good 10 minute run my truck ran out of gas so i went and checked the temp, which was around 330. I know that commonly this is high but did not know if this was maybe usual for this engine. It has always seemed to run fine except for a little bit of hesitation off the line and has always had a decent amount of blue smoke. Which needles should I richen, and possibly how much of a turn on them? Thanks for the help.Also the engine has good air flow, the body is almost all the way up there on the posts.
