ok i have been messing with this motor for a while now. It seems to no power when i give it full throttle. it will start backfiring when i use the trim controls or the tilt. its a 21' searay cuddy walkaround with a 305 gm motor. i just had the carburator rebuilt which cost alot. its a edelbrock 4 barrel 1409 carb. i checked the timing as best i can and when i raise the throttle i see it advanceing. Very strange and VERY frustating. I check all spark plugs and wires, put a new cap and rotor on. I dont know what else to check. Any help would be greatly appreciated./ it starts and idles great. I also checked compression on all the cylinders and there all about the same.
thanks for all your help
