yes, I looked at matt's how-to. Very informative. Thanks. I will be using it during the rebuild of course. This week I am going to order all my parts from Chris Whestfall. Why does he show his carb kit ending in an S? It shows 25 757 01 S. What does that mean? I will go and get the screws at my local ACE. They have a HUGE section of nuts, bolts, stainless, etc.

My local hardware store did not carry that size, the smallest they had were #4....I had to order some from fastenal, they were cheap too but the shipping it bumped up the price to around $8.50. I could have drove to a larger town and probably found them, but with gas nearing $4.00/ gallon, I did not think the $8.50 was that out of line.

what are the locations of the low idle screw, and high idle screw. I have looked at pics and manuals and not one gives a specific answer to what screw is what. the closest i got was the main needle. that does not help me with adjusting the low and high idle. i need to know what the main needle is?

what is the top screw
what is the side screw under the idle speed screw?
thanks
mike

was the throttle shaft supposed to have a rubber O ring in it and the brass bushing was the upgrade? or did someone just do something really stupid?

No O ring, the carb body kept the shaft tight. It will wear out over time, therefore the bushing takes up the slop and fits into the recess.
Hope this helps you out some.

yes, it helped out a lot.
It,s great fixing other people's fine mechanic skills to make things work how they should.
What really upsets me is the guy we bought the tractor from said it was a brand new carb. Just looking at it, the carb did look new. It was nice and shiny on the outside but on the inside nothing was done correctly.
thanks,
mike

Don't forget the big fat gasket (spacer) that goes between the carb, the carb gasket and the block. It's a quarter inch thick and will improve performance.

Good timing on this. I just started up the 108 and gas gushed out the air cleaner and bowl like a faucet was turned on. Guess I'm next, huh? I've never been inside a carb before. But I have to rebuild my Kawasaki carbs soon so I think this will be a relatively painless introduction compared to that...

Put it this way... short of setting the correct adjustment of the float, you could do these things with your eyes closed.

Nevertheless, I think I'll try at least the first one with eyes open.

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.
