If they have never been apart to your knowledge, I would get carb kits for em before tearing em apart. Once gaskets get to be about 7-8 years old they tend to lose there pliability and get brittle. Try a HEAVY shot of SEAFOAM and gas through the fuel system first though. Get a small tank and hook-up with 5 gallons of gas in it and about 1 quart of SEAFOAM in it, and I like to mix in some BERRYMAN CHEM-TOOL with it as well(about a pints worth). Run it for about 15 minutes and then let it sit for an hour. Then run it again for 15 minutes and let it sit overnight. Start it up the next day and see if it will idle. Best case scenario this will flush em out and you'll be good to go, worst case scenario it doesn't help your carbs but de-carbons the engine which it probably needs anyways and you have to build the carbs anyways.
