I have two MVVS's one 45 and the 58Pro they are both still in new condition, very powerfull with the correct cannister exhaust, don't use a Pitts restrictor sorry silencer? on the MVVS they improve out of all recognition with the free flowing exhaust, On the 45 I am turning a 22x10 Mejzlik at 7150rpm x 83Db, the auto choke is very good also, the throttle responce again with the cannister is better than any other motor I have tried, I have my throttle set up linerly so that at half stick I get half revs, that is half the difference between tick over and WOT, Walboro carbs only operate over the first third of opening, very little difference between third open and WOT, so be wary of those that say they hover (prop hang) at half throttle. Mass's of aftermarket cannister exhausts out there also its easy to get manifolds even specials.

Sold my DA and my DL.
