Sounds like typical bog on accel and slow return to idle.

Try some choke 1st to see if it goes away. If it does, open the fuel screws (CCW) 1/8 to 1/4 turn each.
On Raptor#1 I feel like my power band is flat from mid to full throttle, like doesn’t pick up as fast as it does from idle to mid.

Swapped 148/150 have a nice idle, revs through but header is glowing.

I think this radiators toast cause I installed the overflow they had plugged up and filled radiator cause it had some missing even though I filled it. So tested it a couple times and noticed a hiss around the thermostat area which the radiator needed so more topped off and it wasn’t being sucked back from the overflow cause that was full. Sound about correct to replace?
