Hello all im new to this board and am looking for some help, i just got a motor like this and it is supposedly rebuilt, it looks it too, i have done the whole half throttle thing for 20 hours already, and i seem to be having a problem, when in drive, i will gas it all the way and it will run like crap, but if its only half way upit runs ok, also if i pull the throttle all the way back till it wont go anymore it cuts off, im trying to figure out why this happens? cause it bites to take 20 mins. to get from one side of the lake to the other! <br /><br />I use a 50:1 gas mix and have a new tank tube and bulb the fuel pump is new and the carbs are supposedly rebuiltany help thanx
