Right now I'm using the timed spark port on the side of the metering block to supply a signal to my BRPV. I put a boost controller in line with the vacuum, line, and I noticed a little fuel on the boost controller. I unhooked it and found out that revving up the motor in neutral was causing fuel to come out of the port. I'm guessing that I have a bad metering block gasket. I'm running the good reusable ones, but I've took them on and off a lot to change jets. I ordered some new gaskets, but is there any other way fuel would get to this port? I checked my float height and it was right on.

 

Make sure that the PV diaphram doesn't have a leak or hole in it. I've seen that before plus I use some of that 3M glue when putting the carb back together around areas that may be prone to leak fuel.

 

Alright I'll check the diaphram. I remember reading that you use that 3m gasket glue on the PV gasket, but I haven't every tried it. I'll have to pick some of it up. Thanks for the help.
