Re: Rough during warm-up enrichment period



Dave -

I took out the relay, checked the wiring on the socket ala Bentley, and
shook the relay around a bit before putting it back. Then this morning
it did the same thing: ran fine for ~60s, stalled, hard to start, ran
poorly, gradually improved over ~15 minutes (after the temp gauge was
already warm) until everything was fine. Any more advice?

Thanks,
Wallace
