carb.........
hi,i ran into a problem kind of like that a few years ago,we pulled our hair out over it. what it would do,was run fine at a slow speed,but at 60 mph,it was like turning the key off,at 45 it would start again,.at 60,cut off again. we checked everything out,finally we took a long gas line hose,ran it into the gas tank,duct taped the hose to the side of the car,then put the end of the hose into an adapter,and then into the fuel pump,we could run 100 mph like that with no problem,we hit the books and found that there was NO envelope type filter inside the tank,we dropped the tank and there WAS a filter inside the tank,it was plugged up. we changed the filter and added another filter to the chassis and had no further problems..im Boatbob2
