at what point do you just put on a new carb
I have ben working with my carb 4160 holly. I have adjusted floats made sure everything was exactly how holly recommends. fuel mixture screws set and still having problems. my timing is set to 10 btdc. just put new plugs in and when i put my boat in the water it will fire first bump of the key. it has never done that sense i have owned it. runs great no hiccup or anything. the problem inlys that at idle i still have fuel on the water out of the exhaust. if i turn the air mixture screw in a 1/4 of a turn the engine will start popping as running across the lake and the exhaust is not near as bad but still their with the fuel. if i leave it it will run great but have unburnt fuel in the water and a really bad fuel sitting on the water. it will start hot or after i let it sit. at what point do you thow it in the trash and buy a new one or brake it all down and rebuild it. also to me it kinda idles a little rough but that might be its a v8 in an older boat. any and all sugestions are apeciated
