Hi there,
I have a little problem. My rear carb is over fuelling from the overflow and hence the jet too. I've had the float bowl apart and found a little debris stuck around the float valve causing it both to stay open and also not to allow full fuelling.
I have cleaned the valve out but it is still over fuelling out of the overflow. The front carb is fine. I did check the float heights when I had the carb off and noticed the rear float was a little sticky when fuel was being trickled into the inlet pipe. I have cleaned the float pin and thought it was fine but obviously not. I think there may be a problem with the weighting of the float as it appears a little reluctant to rise properly when fuel is entering the float chamber.
I have looked at the stay up floats from burlen (su) and wonder if these will fit the carbs.
Has anyone on here experienced this or have used the burlen stay up floats?
My carbs btw are round top hitachi su's 3 screw variants. They have been vapour blasted and therefore immaculate.
Any feedback would be most appreciated
Thanks, luke
