With everything put back together I decided to try something. So I ran a line from a bucket of water to the raw water pump. The bucket was filled with fresh, clean water and a garden hose to keep filling it. With water flowing into the bucket and filling the tube with water I turned on the engine. It started up without a struggle at all.
I turned it on and let it idle for about 4 minutes and then pulled the RPM's up for a couple minutes. Then I lowered the RPM's down and let it idle for another 5 minutes before turning it off. Everything ran like a champ! Water came out the exhaust and there was no black, blue or white smoke, there was very little in the way of exhaust at all (other than the water). Problem 1 is that the RPM's don't show up on the tach so I gotta fix that.
I left the transmission in neutral as I have not topped up the fluid yet but all in all I feel like I had a successful couple days.
[/b]So Should I have a mechanic come in to do a tune up?[/b] All signs are good so far as the engine didn't hesitate at all, turned on with no issues, stopped with no issues. No loud noises, no chuging, ran smoothly as I throttled up and down...
