Hi, a/m engine is fitted to a Suzuki jeep. seems to run well but top speed with pedal on the floor is down to 140 Km an hour (without head wind) and revs mx 4200/4300. There is a gap between accelerating start and actual accelaration start on the pump. Cable cannot be adjusted anymore. There are no leaks visible and no smoke comming out the back. I used to be able to push up 5000 revs occasionaly. This pump has no gas adjusting screw.
Any help on this please?
many thanks
Al
