RE: tower 46 troubles
Craig,
I had a very similar problem to this with mine last year. My friends also was doing about the same. What was wrong with ours was believe it or not the low speed needle setting. I made the mistake when mine wasnt running right of turning the low speed in untill it bottomd out, then back 2 turns. This isnt even close to being right. If you have your manual for it yet check out the setting for the low speed. You have to go to WOT, then use a drill bit to set the space between the low speed needle and the spray bar. Its something like 7 or 8 turns out. If its in to far it actually goes into the spray bar and even at WOT there is no room for the fuel to come out. If you need the instructions I think I have my manual in my flight box. I could copy it and fax it to you. And your right, these engines scream like wild little banshees.
