After an extensive rebuild of most things in the engine bay: head, carb, IM, P/S, A/C, cooling system, etc. I am still in the first 500-1000 miles or so of shakedown from having everything reassembled.
Two weeks ago I made it about 65 miles on a 100 mile trip before overheating. I was cruising on the freeway, above 3K rpm, pulled off the freeway to get gas and when I did the temp gauge went into the red. As I rolled into the gas station and shut it off, coolant started bursting from the water pump (the one part of the coolant system I did not replace last year).
I towed it home and ordered parts. Installed everything this morning, filled it with coolant/water and it started right up and idled. Temp gauge stayed at 1/4 at idle. Went for a drive and temp gauge went to 3/4 and stayed there, going slightly up when stopped and down to 3/4 when cruising. I stopped at the market and upon shut off it dieseled for a few seconds.
Started right up and idled no problem. I ran it a bit hard on the way home to put it through its paces, and let it idle for a few minutes when I got back home. Temp gauge went up close to red, but never met the line and stayed there. When I shut it off it dieseled again. Engine was definitely hot, I could hear what sounded like water boiling, and the overflow tank filled up and was spitting coolant.
I set the front end up and let it cool. Once cooled, the overflow was now empty. I filled more coolant while pumping the upper rad hose until all the air was gone. It started right up, but will not idle. Tried it with choke, no choke. It won't idle.
That is where I am at.
