so what did u come up with, i also have a hjr duner hillshooter ported motor, 4 mil long rod, high compression for 110oct like 18cc, vf3 reeds, t5's and stock carbs with pods. i was told to go 330 or 340 if wanted to be safe and thats at the imperial sand dunes(oh and pilot could stay stock 25). well 340 was rediculous lean and throttle was not snappy< low end bogged. went to 27.5 pilots 1 1/2 turns out on mixture screw and main to 360. throttle snappy now and no more boggin, but main still lean looks like could go to 380 atleast. i just did a pull today in phoenix with brand new plugs that i put in after warm up and shut down while runnin wide open so i know i got a good read.
curious to see what u had come up with
