The carb is the same as a G62, bigger than it needs to be but works fine...start your adjustments 2 turns out on both needles, adjust the high first...The carb has a pulse hole that lines up with the hole in the insulator block..The black hose from the case to the block is for the pump function..You can turn the carb any way you want if you put a fitting in the back plate of the carb to connect to the black hose...fFttings are from Walbro, part #128-218..Drill the carb back plate with a #23 drill and press it in..there is a cast boss on the plate that's not drilled, that's where it goes...bennettbuilt.com has the fittings, different part number, I think his are all metal...If the hole gets too big some 5 minute JB Weld will hold the fitting in, theres only about 6 lbs pressure on it...Grind off the fitting flush inside the plate....Plug up the hole in the block to prevent any leak....
