no need for a flame suit Dave, I have actually had the best luck with TT engines but i know some who have not . I had a few bad exp. with O.S. engines so i dont buy em anymore, its all pref.
The TT .40 and 46 are great little engines though, I have run my 40 to death for 3 years and it still hauls butt. my 46 runs good too.
IF I purchase anymore 2-strokes they will be thunder tiger. four strokes i buy saito.
