My tower 75 is on the shelf right now since I don't have a plane for it...the plane died in a crash where I lost throttle...then elevator fluttered and you could imagine a 10 minute flight with a tower 75 at full throttle with an apc 12x7...with a fluttering elevator....that pain was never ending...after ten minutes the elevator broke and I had the chance to crash the plane safely... the carb broke on it's throat.

I ordered a JEN .91 replacement carb that fits perfectly on diameter but still have to grind the throat on a lathe since the throat is a bit longer and stays a couple of mm higher than it should to seal perfectly (anyone could give me the exact throat length on the original carb??)

This engine is definately the funniest engine I ever had!!
