Does the plugs show it to be running lean?

I guess it may depend on what regulator you are using?? I use an adjustable pressure relief valve (diaphram type) on the rear of the fuel log to control the pressure via the return line. This was the recommended configuration for my regulator. I would recommend you contact the manufacturer or reseller of your regulator to find out.

If your running you regulator before the log, the return line should be plugged or the fuel will just flow past the carb inlets straight to the return. Im no expert on fuel delivery by any means but its common sense that if a return line is used the regulator needs to be at the back of the log past the carb inlets th keep the desired amount of pressure in the log and the released fuel back trhough the return line. I think the way you have it set up now could definitly cause fuel starvation to the carb.

I think there are regulators designed to be used with no return, probally the type rat trap has.

That sounds alot better, I was wondering how your motor was even running if the fuel was flowing through the log straight to the return line. Your right though, you can probally do away with the log and go straight from the reg. to the the carb.
