Hi!
Before reading I?m not whining.
I bought a old engine 2 years ago. It brought me only trouble
Amount of time spent using it is less than a few hours. This is the story.
The seller told me the engine had been refurbished after an overheating condition. My mistake for beliving him. He said that one piston and two rings had been replaced. After the first very short trip, it overheated again.
Took the head of and found pure missery. Instead of changing gasket he had used som sort of sealing silicone and clooged the two broken/melted head connectors passage. So no cooling to the top half. Before the first run I changed the impeller just in case.
Ordered new gaskets and connectors and refurbished that part including changing the thermostat. Happy enough i took it out for a second spin. This one lasted the rest of that summer, but the water light was flicking on and of around 3000 rpm. So I could never try it at WOT. Also it ran poorly on idle due to flooded carbs.
For the sake of it I checked compression and noticed one cylinder of the mark. Disassembled the hole engine and refurbished with 1 new piston and 2 new rings. New gaskets all the way. Also refurbished the carbs whith new needles. Back on and now it had gone 2 years since i tried it the first time. Since the cooling water sensor had flicked I also replaced that one to a new. Hoped for improvment i started it up. No luck. The water light went of ~10 sec and with some throttle it came on again around ~3000 rpm, but not consistent. Sigh!!!
Now I hoped it would be some clogging in water inlet or damaged impelller, but that was not the case. Refurbished the water pump anyways with new gasket and impeller. Tried it again, same result but now the water light came on even on idle. At this time acctually, yesterday, my patince was running really thin but as a final adjustment took away the sensor to check if any water was reaching that point.
To my surrprise it was bursting out and when flipping the water sensor bulb the water light did?nt change accordingly. So it is the f***** water sensor that has given me all this trouble. And it is new!!!
After further studies i noticed that the water light came on just as the engine reaches normal temp. It does not overheat, at least at idle for 30 minutes of fiddling. So correct me if I?m wrong, but the sensor shouldn?t react to heat right, only to water flow? It is the new sensor with 3 wires, though i only use 2 of them. How do I remove this sensor so the rev limit doesn?t kick in? I tend to change this one also but i would like to test my engine with more rpm then 3000.
Sorry, long first post.
