1980 arctic cat jag bogging out when give it gas and there is gas coming the exhaust and out the back of the carb into air box HELP ME?

Sorry, but it's a machine used in very harsh environmental conditions and it's nearly 35 years old. There's no way for anyone here to give you anything other than guesses unless they know the maintenance record and can examine the machine directly.

There are so many potential causes for what you've described that you really have just one option: get an experienced professional or home mechanic to check it out.

I has cleaned fuel tank and new plugs and Rob steriack I asking this because I have seem this same problem in other sleds the same year I was wondering if anyone would know a little more than me it was always in a garage its whole life low miles great shape my grandpa bought it (he isn't a fast driver ever) and I understand that its almost 35 years old I was also wondering if anyone thought it could be the fuel pump just asking for guesses I don't care anything helps
