The crap gas we are now using will cause all kinds of problems with early cars fuel systems from the valves to the gas tank. Gaskets and any flex fuel line are st the top of the list. Stuck valves are also high on the list. Fuel filters stop up. I always use a particular gas additive and start and run my 2000 more than once a month through the down times.
Good luck

> I had the same problem on my 1600.? Car ran terribly.? I sprayed some carb cleaner around the intake while it was running and the idle increased, signaling a leak.? The gaskets between the carbs and intake?had basically disintegrated.? Check there to see if that is your problem too.? The gaskets at the air cleaner should be there too for proper air flow once you have balanced the carbs.Good LuckRoy H.
