Ok guys first I wanna thank you for all the info ive found on the forms, I've recently rebuilt a transom in my 19ft Aries 200xlt bass boat and it was invaluable, i have picked up a motor on the super cheep to power my 19ft bass boat (75 hp Chrysler 758h2e) yes I know it's extreamly under powered but it was the most I could afford being a broke college kid, the motor ran but not very well when I picked it up it would die at anything above 1/2 throttle, thinking a simple carb cleaning would help I picked it up, there was a TON of junk in the carbs I cleand them out set the floats correctly and re asimbled the motor runs much better and smother but still seems to bog down and eventually die at 3/4+ throttle being underpowered I need that little bit to get on plane, new plugs, new fule lines, cleaned fuel filter, good compression, im at a loss original owner mentioned something about timeing but I'm not sure I'm that skilled to embark in that endeavor....... any advice would be appreciated!
