That is way cool!

I'd love to have it but it's too much for my budget.

Very nice XL115. I have one too, it is not too useful, unless you want to run 2 60watt light bulbs. It is 400 cycle/Hz for running a small portable radio that is compatible with aircraft electrical systems. It only puts out 125 watts at 110 volts. It will not run a normal motor or anything with a transformer in the power supply.

54 cc XL-12 engine, a big muffler, provision for long term running with a remote fuel tank, sweet air tight (if the corner is not bashed in) storage case. Originally came with some spare parts, tools and a manual.

I would say he is asking way too much for it.

Damn cool though, I really like mine in spite of never having found a real use for it.

nice, small portable shame it has such low wattage

I'm actually very interested in it. I've never reached out to someone that far away with a craigslist ad but I might have to try my luck with this one and at least make an offer. I've all but given up on ebay it seems sellers just get worse and worse. If the guy will ship I might be into this one though

I would love to get an old military radio to go along with one of those.

I have to wonder why only 125 watts? It can't be working very hard to generate that power!

754 watts is equal to 1 electrical Horse Power so the output is on the order of 1/6 Hp. With inefficiencies factored it, I am gonna guess the the engine is putting out about 1/2 to 3/4 Hp. I have forgotten what the actual number is but the manual gives a very long run time on the built in fuel tank. On the external tank it is unlimited of course. Miles from no-where when everything has to be humped in, its important that you don't have to carry extra equipment in the form of excess gen capacity, or fuel to keep it running.

Just as an interesting tidbit, the gen has no bearings. The armature is a permanent magnet cup, fastened to the crankshaft with its bottom away from the engine. It "cups" over the stater with its windings and is spinning in free air without any housing. There are no brushes, external guards or other parts, just the armature and stater. The two leads from the stater connect directly to the duplex power outlet, no voltage regulator. The radio is expected to internally regulate the power it needs. There is a fine adjustment governor to control engine speed, the 400 Hz must be more important to the radio than the 110 volts is.

The 400 Hz design reduces the amount of iron in the gen and thus the weight but anything expected to use this power needs to also be designed for 400 Hz.

Incandescent bulbs work fine, they are not sensitive to cycle rate.

Here's an XL115 "gen" for sale with the gen missing. The alternator has been scavenged off it, there are no electrical parts, and it has not been treated well. No case. I would have put it in Craigslist but I cannot imagine a reason to buy this unless the shielded ignition was needed or you "just had to have it". The pictures do show how the alternator gets mounted and the governor case, between the engine and the alternator can be seen. The governor control is on the top of the governor case. I don't know for sure how it works, I believe it has fly weights as opposed to the general use by Homelite of air vanes in the starter case.
