AND NOW an ANNOYING story from the old days.
From about 80-81 to maybe 89 I worked at what was then a large local auto / industrial parts supply. We had "everything." Full line of auto/ light truck parts, popular parts for over the road/ logging trucks, made hydraulic hoses by the hundreds, stocked a full line of Gates industrial/ auto belts, and sold Browning sprockets, chain, and sheaves, Fafnir and Timken, and on and on. We had a complete welder/ supplies/ gas bottles store and repaired welders and oxy/ acet components
ANYHOW late one late fall some guy comes in and waited for me. "He had heard" that I was the electronics expert. He had an old V4 OMC that was electronic ignition, and back then the Marina wanted ?? 500 bucks or some such for a replacement ignition module. He wanted to know "was there" some auto parts he could adapt "cheaper."
I told him I had no good ideas on the subject, and he would not leave witih that answer. We were busy, and I finally told him, "look, you might just screw around and get something working, and IF that quit you late some afternoon, you might spend a cold night up on Pend Oreille
"OH," he says, "THIS IS NOT ON A BOAT. THIS IS FOR A HOME BUILT HELICOPTER!!"
