I decided to get my TT 91 out of mothballs and see how it ran and what the needle settings were. I got everyting setup on the test stand for this morning then discovered that Ididn't have a prop spinner to fit that didn't have a bent back plate. I did discover something though.After pulling the plug and pulling the barrel out of the carb and soaking things with some after run oil. Idiscovered that there is very little compression on it also. Then the light blub went off, my two TTtwo strokes feel almost like there isn't a piston, the lowest static compression I've ever seen, this 91 feels the same. I was making a comment about it to one of the guys at the field this morning and his comment was that all the TT engines he has seen had what seemed as little to no compression, but all ran well. I know my 46 two stroke is a great running engnine once I got it tuned in. I have some spinners on order and they should be here by mid week and I'll get a sense of how this engine is going to run and will post the results.
