The easiest one for a beginner would be a model 92, single. Most all is available for them. Rings, gaskets, check valves, plugs, condensers. The 72 twins are great runners but many suffer from the 150.00 Replacement, bad coil. So, the 92 would be a great starter engine.

I wouldn't worry about the expensive coil replacement on a maytag twin after all difficulty wise they both are easy engines, you can get everything for these engines and it is just a matter of taste. Do you want a hit miss cycle or a throttle governed style engine. I have one of each and i found both easy and enjoyable to rebuild.

I find the purring of a 72 to be soothing and relaxing. The harsh, irregular pop of the 92 gets old in a hurry.
Just my opinion......

The 72 styles are nice even runners. There are 3 of them. The 72-D and DA look identical, only difference between them is the ignition - slightly different mags and flywheel ID. The 3rd is the WICO version. You do not see as many, but they too run nice.

The 92 is a 'hit and miss' single. Easy to find and get parts for. Without a muffler, they are a bit noisy, but that's the charm. if you do decide to get one, either get a Maytag muffler (there are several styles) or get an adapter and put a 3/4" B&S long muffler on it. Don't use the chincy 1/2" mufflers sold on EBay -they are too restrictive and will cause the engine to choke up the exhaust with carbon. the B&S muffler will work on both engines, the trick is th get the 3/4" adapter that will mate it to the exhaust flange on the engines. Although all the 92s look very similar, there are variations with them too. 4 different fuel tanks, some came with air filters (different carbs). All are good runners. it is really neat if you run something, like a fan or water pump with them. Makes them bark a bit!

price wise, the twins and 92s are about the same. Out here (NJ), they go for between 125 and 175 for a running engine. One thing to lok for - turn the flywheel gently back and forth. If the flywheel moves more than about 1/8 to 3/16 of an inch, you will have to go inside and have a look at the connecting rod, and machine down the end cap to take off some of the play. if the flywheel turns more than a 1/4" before the play is taken up, then a new con rod will probably be needed - at a minimum.

If you are looking at a twin (72), make sure it has spark on both sides. DO NOT pull a spark plug wire off when the engine is running - sure way to kill a coil on the 72s You MUST stop a 72 by opening the air cap at least 2 turns open to stop the engine.

Remember OIL ratio 16:1 - 1 cup SAE 30 non-detergent OIL or A good marine OIL not lubricant Type TCW-3 is best if you do not use the SAE 30. The Maytags all have solid phosphor bronze con rods. No ball or roller bearings. They also do not have seals on the mains - they depend on a tight fit to keep oil in and air out. Modern lubes ate too thin to maintain a seal. Some guys are cutting the ratio to 20:1. I do not recommend it. Too many ruined engines because of it. By the time you hear the squeal of dry bearings, it is too late. The damage is done.

I agree, both the 72 and 92 are great starter engines. Normally someone beginning wants to be successful on their first try and may have limited resources. That's why I mentioned the 92 as first choice. Normally not a bad coil as the 72's are prone to have. The 72 is a sweet runner. I have 2 Eismans and one Wico. Depending on what's availiable and for what price may determine a choice. Yes, a muffler is a great option to not bother your show neighbors, and several things can be powered by them. For summer shows, a box fan, is a big hit.

One more thing, follow Andrew's oil/mix instructions and which of any, you choose you will enjoy many hours of trouble free running.

Aren't the 92s ignition governed? Meaning they're chugging out fuel when run without a load? I'd want the 72 twin.

Twice I tried to get one of the Winco generator versions on fleabay, but both listings ended up posted on here, then quickly got bid up way too high.

For starts ebay is going to always be very high when buying engines in my opinion.... Second a maytag generator version really goes high and it is not surprising but on those ones you have to pay to play. If you want my advice i would suggest you get a nice maytag twin and learn to restore that engine.. next find something fun like a small water pump or a air compressor pump or something that the engine can drive while it runs and restore that. Also look out for estate sales as if you want the really good stuff it hides there and will go cheaper than ebay in some cases. Believe me i have watched many a good engine sell on ebay that i absolutely have wanted and i have seen plenty more go way above what i feel they are worth so dont get discouraged go have fun and make plenty of smoke.

Next question is where would I find stuff that these Maytags can power? Iím just going to assume in the same places and the same people as these antique engines. The only thing I currently own that might work is a York A/C compressor that was converted to pump air (i believe as I found it at the dump) but I donít know if it can work.

Exclamation Re: Good Maytag Engine for a Beginner?

Depending on the size of the air compressor, the Maytags may have trouble with it. The 92 single is rated at 3/4 HP - and that is the point where it is hitting at every top center and firing. The twin is only 5/8 HP, throttle wide open. neither engine will fare well under such load. Also, the twins pistons are only 11/2" in diameter. For most applications, the piston on the compressor needs to be less than that of the engine, otherwise, you will stall the engine. A better choice would be either a small water pump or perhaps a small knife sharpening grindstone. As the Maytags are low RPM (less than 1200), these should work well without overloading the engines.

The 92s are 'electrically governed', in that the ignition is interrupted as the engine gains speed. On the 82 and 92s, as the engines speed up the governor closes down the points, which in turn advances the timing a bit. Eventually, the points so not open, and the engine coasts down under compression, until the governor again opens the points. This accomplishes 2 things - it cools the cylinder and allows fresh oil to lubricate the cylinder and piston at the same time.. The draw back is that this 'wasted' fuel and oil get dumped out the exhaust.

The twin 72 is throttle governed. The governor is mounted within the crankshaft. Intake timing is by port and machined passage in the crankshaft - one reason the twins won't run backwards. As the engine speeds up, the governor cuts off the passage thru the crank, which then limits engine speed. The hole thru the crank is only about 3/8" in diameter, which limits top speed if the governor is removed or gets stuck. I have seen twins, where a modern carb and reed induction has been installed on the block. With titanium rods, a solid billet stainless steel flywheel and modern points, these engines can reach 16000 RPM! DON'T DARE try that with the bronze rods and aluminum flywheels the engines come with!

Both engines, the 72 and 92s have their own merits. if you want a quiet steady speed engine, go for the 72. If you like the 'hit and miss' sound, go for the 92. By the time you are done, the cost is about equal.

So looking around There are 3 models of York compressors. They all have the same bore of 1 3/4 inches and they all have two cylinders but they all have different strokes. The small has 1.105íí the medium one 1.573íí and the large 1.866íí. I believe I have the medium one but Iím not sure. I canít seem to find anything in the actual piston size either.

If you only intend to run some small model steam engines or blow up balloons, then your maytag probably will run the compressor. if you want to blow up tires, that is another story.

I got a not running but otherwise decent shape 92 for $75. Condition unknown, came from an estate. Quickly determined it was not getting fuel, read up and found out there is a check ball in the pickup tube, was gummed up and not moving, once I cleaned that up it fired right up and runs good.

But, other than making noise, smoke and a puddle of oil under the exhaust, its not that exciting. Would be fun to put one wo work but with the small power you need to get creative.
