hey guys new to the forum page having an issue with a 97 scrambler 500 non h.o, my issue is when i have the air box in with filter (brand new) it will start and idle but as soon as i put a good size load on it, it bogs out and starts spitting and sputtering if i remove the air box completely it will run fine. i bought the wheeler knowing that it had this issue i have found that some of the carb adjustments have been really far off i adjusted the jet needle to the 2 position from the top was set at 5 i also set the idle mixture screw to 2 1/2 turns i've gone through all the passages also set float bowl level to factory specs the slide diaphragm seems to be working smoothly also checked the choke all was ok i just picked up a valve and needle seat cause i did notice the overflow dripping but i got thinking if im over looking something else and its actually not carb related but there might be another underlying issue with the motor so i did a compression test cold, throttle open got about 28psi did another test warm and got 75psi now i know these have that decompression release in it any ideas on what compression should be? am i headed in right direction? or any ideas? sorry for the long right up
