makes me wonder if the ignition is up to snuff.

Good point

As far as the ignition goes it's the factory mercury ignition, new plugs and wires, set baseline at 13

they are mooneyham blowers with mooneyham intercoolers, intakes and carb adaptors

at this point i think you need to have someone with blower motor experiance take a look at it,it is tough to figure out what is going on without seeing it.

Agreed, blew a driveshaft end up and getting another one today. Will test this afternoon/tomorrow and report back

where's the fuel pressure at when flooding ?

TruxtonFox 07-12-2017 08:51 AM

Stays steady between 5-7

ezstriper 07-13-2017 02:54 PM

I do not see a way it could be flooding at that RPM and fuel pressure and be fine at idle, something is scewy here...think you better have someone with blower motor experiance ride with you...
