'91 Sammy runs rough

[Jim Blackwood]

Did a test this AM. Started and ran the engine at about 3000 rpm until it cleared and ran smoothly then killed it with key and clutch. Restarted cleanly.Repeated but let it sit with the key on for a minute or so then started. This time it had a rich burble. Cleared and repeated. The test seems pretty conclusive to me. The injector leaks a bit. Not bad enough yet to cause any major problems but it won't be long before it does. So the injector needs to be replaced but there are none available. Used ones that are probably just as bad, can't be rebuilt due to wear.

Has anyone come up with a solution to this?
