350 big bear carb trouble.I think?
i amworking on a 350 big bear,it sputters and spits when you first get on the throttle and when you mash it over halfway it straighten out and goes.I put in a new carb kit,no diffrence.I soaked the carb in mean green for 4 or 5 days,no help.I then heated the mean green to boiling, then trasfered the boiling mean green to a homemade sonic cleaner I had made with a palm sander let it set for 3 or 4 hours with it running,put it all back together and still no change. I had a 350 bb I worked on a few months back that was running horrible ,I proabaly took that carb off at least 10 times,put a new carb kit in it also,to make a long story short,after about ten days i figured out it was the o ring on the choke stem.So on the bb im working on now that was the first thing i thought it mite be. He said it had been setting a very long time.Its like its in the low side of the carb to me.It doesnt cut completly out at low rpms just kinda sputters.DOES ANYBODY NO WHAT ELSE I CAN TRY??? I ran a fine wire threw every port and hole on it,used compressed air after every soaking and cleaning.. I just dont no what else to try..please any advice will be greatly appreciated.
