Sorry for the long delay. Life kind of got in the way. I finally got around to disassembling the engine on this generator. I saw some corrosion in the exhaust manifold and suspected some water entered through the muffler. The problem was in fact the upper two rings on both pistons were stuck...

Well I tried a small squirt of starting fluid a few times and the engine never fired. I'm going to add some Marvel Mystery oil to each cylinder and let it soak for a week or so to see if has any effect. Thanks for everyone's ideas.

I really appreciate everyone's advice and knowledge. I just got called out of town so I won't be able to get back to work on it until next week. I will do what was suggested and let you know what I find. Thanks again.....

OK, so I tested the MPU as installed. I got right at 1 volt AC across terminals #3 and #6. I removed the sensor from the engine and cleaned the small amount of debris from the magnet. Reinstalled and adjusted so that I now get between 2.2 and 2.5 volts AC (book wants between 2 and 3 volts...

I will check it this evening. I just found the reference to it in the -24 manual.

I have attempted to. The very first step is to check for the stop/start lever in the wrong position. It tells you to adjust the lever as per paragraph 3-23.5. This paragraph then refers you to figure 3-19. This is the figure I previously wrote about that I don't see some of the parts shown...

I also wanted to mention something else I found. In the -24 manual, Figure 9 shows the governor system. Does anyone know are some of these parts internal to the engine. I can see the parts #29 thru #35 which appear to be associated with changing the frequency. I can also see parts #44 thru...

LBCDguy, I don't know to all of your questions. I will check the fuel return circuit tomorrow. I was thinking about doing a compression test but wasn't sure how since there isn't a spark plug hole to thread my tester into. Also, I couldn't find what the compression should be other than it...

Thanks...u was thinking along a different line that maybe I didn't have adequate compression due to a valve not completely closing. So I took off one of the rocker covers and turned the engine over I can see both rocker arms moving. I then waited 30 minutes for the hydraulic pressure to bleed...

Thanks for the help... Yes, it does fully retract. Another interesting thing to add. I removed both the intake filter and muffler so that I could get access to the injectors as I wanted to verify fuel was getting there. It turns out that it is. So the interesting part is that when I turn the...

I recently purchased this generator at auction. It only has a little over 6 hours on the meter. When I bought it all fluids had been drained. I put oil, water and diesel in it. I opened the bottom drain on the filter and ran the electric fuel pump until fuel flowed nicely. I then slightly open...

Robert, I set the MPU back to the way it was (around 4 VAC) and it still would not start. I did not notice any puffs of white smoke from the exhaust so I assumed I was having a fuel issue. I first opened the drain on the bottom of the fuel filter to remove any possible water. I caught this...

A little background first. I purchased this generator about 4 years ago and it ran when I bought it. It only has about 60 hours on the hour meter. It ran just fine last year when I tested it (ran for about 15 minutes) as this generator is used very infrequently. I recently wanted to make...

Walkerman..... I am interested in what you did to resolve your problem? I have one of these same generators and the last time I used it everything was fine. Now I am having the same problem that you are. You mentioned previously that you got it running and the main problem was dirty contacts...
