Well, I was hoping that this project would be done, but it taking a not so fun turn. Hoping it's something simple.
Replaced filters. As I was letting it prime up, the electric pump made some bad noises. It was the original, and the square ones are not the best, so I figured I would change it out since it could have also been part of the problem. Doing both certainly would not hurt. Rather it be right.
Did all that, let it prime again for a bit, & it fired up & ran for a few seconds. Basically, burned off what was in the injection lines.
I cranked quite a bit for 10 seconds at a time to purge more air... no luck. So, for the first time since ever servicing these types of generators, I used the air bleed off screws on top of the fuel filter. They both did bubble. Also, opened the water drain & it came out hard at first as I guess there was some air pressure in there.
After doing that, cranking it a bit more, and it stumbling a bit, it did start. Had to keep at it to purge out the rest of the air but it got there.
So, here is where it has me a bit puzzled.
Engine still doesn't seem to be running that well. I can tell it's struggling. It would run at 63htz with no load and the adjustment pulled all the way out, now it will do 61htz. It's not as smooth. If you apply load, it wants to bog out & die.
I confirmed the new pump is moving fuel. I'm wondering if there is just more air trapped somewhere that is hindering fuel delivery? Usually, the electric pump purges it within a few minuets.
My only other thought is bad fuel. Maybe some moisture got in the jug I had it in & the pickup is taking it in. If this was the case, could have been why it started running poorly after about 20min or so to begin with as that's about how long it took the "new" fuel to make it's way to the injectors.
irritating! Was hoping it would be doing it's 4hr load lest today & be done! But, maybe it is just terd fuel & it will be still, just into the evening.
