I had a (an) '85 Reliant that was carburated; it'd die in traffic because an air fitting on the front of the carb was missing. It'd act as though it was starving, not for air particularly, but for gas. The fitting is on the front of the carb. It's a small air line. I've forgotten where the hose leads, but I'm fairly certain that a) the fact that it wasn"t hooked up at the carb is the reason it'd die and b) you could pump the bejabbers out of it (if you know what I mean) and it still would'nt flood - you could never smell gas after it'd been pumped. Eventually, on its own, by the grace of God, it'd start. It was rare enough (intermittant?), but anyway, check all your air lines that connect to the carburator if it's a carburated model. If its fuel injected ( I had one of those, too), have the injectors cleaned by a mechanic, the stuff you can buy off the shelf never did ME any good, I'm sure of that; in fact, our mechanic had to replace the injectors on my wife's Reliant - unless you can do THAT yourself, you may have to have a mechanic replace yours, too. I think it cost us a little less than $200. If its carbed, check all your air lines, if its fuel injected, well, just plain good luck.
