Added a vacuum pump and now carb overflows.. Ideas ??
I've been having fuel flow problems with my DRZ and Clark tank.
The fuel doesnt run well, especially with an inline filter.
Well, I added a Mikuni Vacuum pump. The smallest I could find. The fuel starvation problems are over which is great but now the carb overflows after a few seconds.
The floats obviously have to fight harder to close the float valve with pressurised fuel but I don't really fancy playing the "hit and miss" game with trying to set my float height so it doesnt. That's even if I can adjust them enough to fight back the pressure.
Is there another method to compensate for adding a fuel pump when there wasnt one intended ?? A different float valve perhaps ?? A flow restrictor ?
Thanks in advance !!
