Hi, i recently did a duel carb swap on a 1995 civic DX, and well the i changed the origonal twin carb conversion to see if a mates twin carbs would work, and well the car runs hidiouse!, i have dont a full service and all, but still to no avail, to me it sounds like a missfire, however it sparks and the spark plugs are fine, any idea's. (iv had bottom bearings, rods, pistons, valves all for answers) i am well confused...HELP>>>>>
