Well once again im back with my good ol 377/503 swap and i have a question, Recently the engine has been acting up. I can hold the throttle at a certain spot and it will increase speed at a steady pace, Sometimes when i hold the throttle to the bar right away it will speed up then make the deep sound buy not decrease in speed it will stay at the same speed, actually it slowly decreases, its not really bogging because before when the sled would bog it would want to shut off but now i can let off and it will drive normally after a second, Is this lack of fuel or lack of air ??? any help is appreciated guys

Does the condition improve or worsen when the choke is flipped on?
no choke on this sled, but its strange because i can hold it about half throttle and it will increase speed without bogging for awhile ( just across the lake no longer distance to see ) but once i try to go full it bogs
