I've just bolted on a pair of Weber 40 doce carbs . The car started right away and runs well at low rpm , it loses power at higher speeds , now I'm told the carbs like about 3.5 lbs fuel pressure and my MB manuel says the fuel pump puts out 2.0 to 2.8 lbs pressure . Has anyone else done a weber conversion ? and have you had to change or modify the fuel pump ?
Thanks , Nick Newell
