RE: AVOID THIS ENGINE AT ALL COST!!!!!
I'm going to have to retract a statement I made earlier about the tower .46.
I was bored yesterday and took it down off the shelf it's been sitting for 6 months, and bolted it to a test bench. I screwed with it for about 3 hours off an on, and finally think I got it purring along. needed a piece of fuel tubing slipped over the needle valve, low end needle completely reworked, and RTV seal put on the backplate. Now the thing idles smooth, doesn't load up on me, transitions nicely, and seems to be spinning an 11x4 really well at WOT. (don't have a tach yet.)
I haven't given it a clean enough bill of health to put back in a plane yet, but another day on the test bench, and I might put it in a trainer to use for testing. Good plane for deadsticks should they happen.
