Got the engine Started! Now to trouble shoot odd running patterns

[LemonShark2]

Hi All,

After posting a few weeks back about my engine not running due to what I thought was water in the fuel, I made some significant progress. Siphoned out the fuel and separated out the water, as well as emptying the fuel filter, and fuel bowl right before the carb, which also had water in it. I primed the whole line up to the bulb, and hooked it back up.

I also changed the Oil, which was black as hell, but not milky, so at least there wasn't water in there!

I tried starting it a number of times, to no avail. I popped out a spark plug, and noticed it as bone dry, so I went ahead and used the hand primer about 100 times (should it have resistance? I didn't feel any pressure.)

After a couple of tries, I got it running again, for about 10 minutes, however the action of the engine, and its running pattern was very odd! At higher throttle, it did this odd thing (see video) I turned it off after getting nervous.

Here it is with the throttle just about where I usually leave it for idling. Sounds Healthy! Except then I noticed a bit of smoke...

It eventually stalled - my theory is overheating - check out the water out the exhaust. I remember reading it should be a steadyish stream, where as mine is just spitting it out bit by bit. Doesn't help that my thermometer isn't working.

So hoping this is just my flexible impeller needing replacement, so i yanked it out and am about to order one...

At the very least, I'm happy I got it running - as I feel like a running engine, even if not running well, is probably better than a non-running engine!

Bonus video, you kinda see how much amazing engine access I have to work with... Maybe youll also spot something I need to fix!
