I have three GMS engines... a .47 in a cub, a .60 in a Pica Cessna 182, and a .60 in a DR1 Tripe... all run really well... good power and they idle nice... the one thing you need to know is it tells you to initially open the needle valve 2 1/2 turns... you really need to start at about 4 - 5 turns.... otherwise they run really nice... especially the two .60's
