Default Cub Cadet 782 Woes.
This Cub Cadet 782 that had sat for 15-18 yrs, was brought back to life. Everything was going well. I was cutting like a champ my 1.75 acre lot. I put the machine in the shed when I was done, and everything was great. Fast forward 2 days, and the machine started to leak from the bowl of the carb. Great thing was that I had a freshly rebuilt carb, that I had in the cabinet.

Installed it, and now I have no fire. I was thinking that perhaps there was an adjustment not right, but I am at a loss.

I am going to check spark first and foremost.

Any tricks to check the carb? I was thinking that it may have a leak somewhere?

Here is what I did. I loosened the intake manifold and lifted it, to remove the carburator. Once I did that, and installed the other one, I saw an arch. Upon further investigation, there was a wire under the bowl of the carburator that was rubbed through. So, I used friction tape and taped it up. There is three wires with a connection near the firewall or dash on top of the engine. I re-installed the carburator and put everything back together, and I have no spark. I have a inline spark detection tool, and there is no light.

Could I have shorted out the condensor? Should I start there or order a coil as well. A Small arch wouldn't do anything else, would it? I checked both dash fuses, they look fine.

Let me know your thoughts.

Looks like this wire needs to be replaced with a new one.

I thought that I have it protected well. It was not cut through, just rubbed the insulation to the wire.

Could that short out the condenser?

You didn't say that prior.

Do you have a DVM or VOM meter ??

I am going to get one. I hope I can figure out how to use it.

What should I do to check it?

Sounds like a wire(s) is grounding out.

Any ideas where to start? Is it possible that the arc could have burned the condenser or coil?

To answer your question, no you didn't hurt the condenser.
follow the wiring diagram and check the wire you fried and determine where you loose the connection/ power.
Check the fuse & holder again. Don't guess,instead test
And you need not loosen the manifold to change carbs
Your original carb is prolly fine except it has something under the needle/ seat or check the float, it is a much better carb than a new off shore carb.
Don't panic and shotgun parts at it.

Cub Cadet is a premium line of outdoor power equipment, established in 1961 as part of International Harvester. During the 1960s, IH initiated an entirely new line of lawn and garden equipment aimed at the owners rural homes with large yards and private gardens. There were a wide variety of Cub Cadet branded and after-market attachments available; including mowers, blades, snow blowers, front loaders, plows, carts, etc. Cub Cadet advertising at that time harped on their thorough testing by "boys - acknowledged by many as the world's worst destructive force!". Cub Cadets became known for their dependability and rugged construction.

MTD Products, Inc. of Cleveland, Ohio purchased the Cub Cadet brand from International Harvester in 1981. Cub Cadet was held as a wholly owned subsidiary for many years following this acquisition, which allowed them to operate independently. Recently, MTD has taken a more aggressive role and integrated Cub Cadet into its other lines of power equipment.
