I have posted this info previously that might help your situation:

The most challenging problem was the Walbro LMB 185 carb. Experienced more problems with erratic operation that did not improve with a carb rebuild kit. Still suspecting it was a carb problem, I sprayed light oil on the carb and intake manifold gasket and had a sudden change in the RPMs. Checked the intake manifold gasket and found it was not leaking. Finally found that the shaft of the butterfly throttle had worn out the bushing in the housing. I was lucky enough on Ebay to find an unused carb that had been sitting on an inventory shelf for 40yrs. It was a LMB 181 and externally was identical to the original Onan carb. I purchased and installed it, and despite all my previous problems, I am in love with this generator again. The operation is unbelievable smooth and power has been restored. Hardly any RPM change when both roof A/Cs kick in. This is even with the electric water heater in operation. Does anyone rebuild or rebush the throttle shaft?
