my buddy bought one of those big bore 2 barrels from speedway and it idles rough and misses if you rev it up and hold it, if you just rev it up and down it sounds good it's only when you hold it steady that it misses, we've tried my carb on it and it runs smooth with it (it's a stock big bore with 72 jets) if i put my hand over the carb to richen it up it doesn't help, it came with 71 jets we tried 68s and it sounded a little better but scared to run it with that small of jets, changed the float out with a new one and looked to make sure the check balls were all in place and everything looks fine. is it normal for a bored carburetor to run rough until you're really in to it? it hasn't seen the track yet so I don't know what it does with a load on it. any suggestions would be appreciated

thanks, i guess we'll try some smaller jets and see what that does for it
