Re: 70hp idling characteristics?

I would NOT use the brass elbow from hardware store, mixed metals could cause corrosion…I would skip the cooling tap elbow update for now, but you can just eliminate the plastic restrictor to see if too much water pressure is causing the cold running…
Please be very careful when you do move the elbow, follow the direction exactly…Drilling too far, running the tap in too deep, might blast a hole through the cooling channel right into the exhaust! What a mess that would be….
