I just put the dual tank on and now I 'm adjusting the carb the hsn is at 2 3/4 but the lsn is at 2 turns.The book says not to go below 2 1/2 turns. There seems to be plenty of smoke and if I put my hand under the exhaust and hit the throttle my hand gets plenty of oil on it. The glow plug has got 1 1/2 gals. on it, if that makes any differance .I only have two weeks into this hobbie just trying not to burn the engine up! Thanks for your time in helping me out!!!
