That's why you buy more than two, right? That way you might have one to sell?;)

Mice can make it through a dime sized hole. I think that 1/8" mesh is a better fix, as some rodents are on the smaller end. I prefer stainless welded mesh, rather than hardware cloth as I have seen rodents chew on hardware cloth to make an opening...

By reversing the male connector to female, the exposed (hot!) pins on the generator cable become enclosed by the female receptacle. The house then has exposed male pins that are unpowered. Much safer. I have a similar pin system, but was lucky enough to find a male receptacle for the house and...

True, but probably feels better than having your ribs being pounded on the machines... Injector testers are pretty straightforward. Before you begin, I would think about where the spray will go before you start testing. Not everyone has a fume hood. All the best, 2Pbfeet

Congratulations on getting it sorted out and running! For me, it certainly took some practice to get the hang of adjusting and setting the clearances on some engines. I find some designs to be more tolerant of uncoordinated moves by me. Once you have the Yanmar valves set, and broken in, I...

The symptoms that you have been describing sound like overfueling, but low compression might also do it. I would start with the head to check valves and cylinder walls, and to see how much carbon might be in there. Keep us posted on what you find deeper into the engine. All the best, 2Pbfeet

The oil filter appears to have factory paint on it...

I think that moving a long idle generator (or compressor for that matter) is a great way to loosen up all sorts of crud. Have you looked in the tank, or drained it to check for "foreign material"? Before giving up on the pump, I would think about pulling it out and cleaning both the pump and...

FWIW: Some acetone in a ziplock bag with the stuck piece in an ultrasonic cleaner filled with water can sometimes greatly shorten the soak times. I try to get the whole part as clean as possible before trying that, and then watch the part for first few minutes of cleaning. Sometimes dirt seems...

Factory Yanmar L70 engines have those tees. However, in my experience, not much fuel ever comes off the injector low pressure line, and if I had an air leak, I would look at that whole return fuel segment as being a potential source of an air leak. If it were me, I would use new hose to run...

FWIW: Generally, the L70s build oil pressure rather quickly, i.e. a a second or two, and with cold oil often to pretty high pressures. (A probable cause of the oil sensor failures in these engines in my own view.) All the best, 2Pbfeet

In my book, oil on the underside of the block/oil pan does not rule out a spill given the oil filter location. A less than totally tight oil filter, or an over tightened oil filter, or an oil filter gasket with debris on it, or defective in manufacturing, can all allow a weep of oil. Around...

@peapvp I defer to your deep real world field experience, but for me tapes, (silicone, silver, copper, or graphite) have worked well and have remained stable in the devices that I have worked with. All the best, 2Pbfeet

I'm glad you checked before! That makes everything easier. That dye is detectable at extremely low levels, although I have never tried to see it on green CARC, so I don't know what the cutoff might be there. Did this unit come to you with large oil stains that might be causing slow weeping? I...

@peapvp If it is a known issue, why not switch to heatsink tape, or a heatsink clip, or a larger, less loaded component that doesn't require the heat sink, to keep the component in its thermal performance zone? Renewing heat sink material every so often seems like extra work at a minimum, but...

@bosko Congratulations on getting the repair done! That is great. Personally, I think components die of some combination of random chance, age, overheating, and / or overloading (current or voltage or power). I see lots of components specified at close to operating voltages, and currents close...

On the bright side, you have a data point. No oil leak, yet. That may not be the data point you wanted. Did you double check that you can see the dye, on say the dipstick, or dribbled off the dipstick on a white paper towel? (Control data point, right?) If it were me, I would have another look...

Any Yanmar dealer, if you have one in the area. (I think that the part is Yanmar 783350-51701, but be prepared for sticker shock.) $250 on eBay at the moment... Chinese knockoffs online if you need it now, just make sure it is for the L70 engine. I have bought the ITACO version for L100 and it...

As @Guyfang wrote, it doesn't take much to short out this style voltmeter, at least in my experience. The wires in the coil are very, very thin. Although I was told a slightly different story that the movement of the needle alone, e.g. in transport, could generate enough voltage to short them...

I'd remove the springs (coils), if it were me. No sense in risking a short to the case... All the best, 2Pbfeet
