The real problem here is that most DIY guys really don’t know how a small engine works, especially carbs. They think that it takes too much time to learn about the equipment they are working on. They want us to do the research for them and then rely on answers provided by other DIY guys who...

If this is a twin cylinder engine check to see if both cylinders are firing. When you report back be sure to include all engine numbers.

Does your mower look like the one in this manual? The part you are looking for is called the traction cable. Let me know what you think. https://archive.org/details/manualsonline-id-3d331076-d519-415a-877f-2156094c276e/page/54/mode/2up

Two things to check the next time it happens. As soon as you feel it starts to quit open the gas cap. If it continues to run, your gas cap is bad, vent plugged, and needs to be replaced. If this is not the problem, purchase an inline spark tester, and check for spark as soon as it quits. No...

Here is how to test relays. To test a lawn tractor relay, you'll need a multimeter and a 12V power source, like a fully charged battery. First, identify the relay's terminals: typically, terminals 85 and 86 are for the coil, and 30 and 87 are for the switch. Apply power to the coil terminals (85...

Was the procedure I posted too difficult for you? If so I’ll try to find one that is a little easier to understand in my files.

I’ve seen it many times that a belt which is the wrong size, too long or short, wrong angle, cause problems which I would not expect. That’s the reason why I always use OEM belts unless I have no other choice. Yes, I’ve seen OEM belt that are the wrong size.

Glad you found the problem. Sometimes it the simple things that drive you crazy.

Belt number should be Ariens 21547188 V-Belt. Your belt may not have the same angle, which is riding to low in the pulleys.. Also check to see if the pulleys are in good condition and the tensioner arm is moving freely.

This site does not have your engine, but the gaskets and carb are the same. Carb part number is 60730 and I think the two gaskets you need are part numbers 36182 and 36183. Hope this is of some help. https://www.partstree.com/models/ult50-500032d-tecumseh-engine/engine-parts-list-vlv40-0/

This manual should answer all your questions. Page 10.6 has the torque specs. https://mymowerparts.com/pdf/Kohler-Service-and-Repair-Manuals/Kohler-Service-Repair-Manual-Courage-SV470-SV480-SV530-SV540-SV590-SV600.pdf

BBill, get your act together. There are two different numbers because you said you need both belts so MParr gave you numbers for each belt. My suggestion is if you don’t understand this, don’t try to change either belt. Might be in over your head.

Since I’m not standing next to you, looking at the unit, it will be very difficult to say what belt length you need. Yes, belts are expensive, but you don’t want to buy a cheaper belt with the wrong angle. As stated, your best bet is to contact a servicing dealer or contact Big Dog directly...

Jack up the rear end and see if the wheels turn at all. Also, remove the belt from the tranny pulley and see if anything moves when turning the pulley. Check at different speeds. Check and see if the brake is frozen tight at the tranny.

Try this site. Searching with the little info you want to supply, as Auto Doc says, can be difficult. Hope I picked the right unit. https://documoto.digabit.com/ui/book/552685
