I am running a 465 stroker with a 450R carb, I started at a 190 main and a 50 pilot with 3 turns on the air screw. It is real snappy and it runs great up until 3/4 through full throttle and it went flat.

So I jumped to a 200 main and it ran better- it is great up until full throttle and then went flat.

So I jumped to a 205 main and it still runs great up until full throttle and it goes flat at full throttle.

Where do I go from here should I keep going up to a 210-215 or should I go back down to a 195-185?

Getting angry with this thing!
PLEASE HELP ME? ANY ADVICE?

Keep going up. The main is the primary jet used from 3/4 - full. I have a 440 stroker with a 39mm fcr and Im running a 205 main so you will probably need just a little more.
