Additional fuel may cause more issues internally, this stuffs simple and your combo isn't unlike 100s of other's just like it that require less fuel and run faster. A fuel restriction or sucking air on the suction could cause it to want more then needed.
Your nozzles, do you have brass filters or foam style? And do you have the o-ring on bottom or top of filter?
I'll get some pics when I get home on Friday and post them.
I have the foam type filters on the injector nozzles.
When I topped off the tank after the last run, it took 2 gallons. That's about what the engine brurned in the staging lanes, during the run and back to the trailer. That's about what I was burning per run with my 565 engine with a carb.
