92 SP starts but will not continue running

[sayoung]

I have this 92 SP that I bought used about 4 years ago.
It did run O.K. but this year it will start but dies after a few seconds.
I have changed the plugs and have a new battery.
Any suggestions on what to check next.

It sounds like you need to remove the carburetors and clean them. If you're careful and don't tear or damage the diaphragms you won't need to buy a rebuild kit. Pay attention to the internal filters too. If you have gray fuel lines you need to replace them with black fuel lines available from auto parts stores like Auto Zone. Measure the length you need and bring a sample with you so you get the correct size. Replace one at a time so you don’t get them mixed up. If you need clamps replace them too. Use small stainless steel clamps also from the auto parts store.

I hope this helps.
