The high speed needle is hollow and also has tiny holes, the holes need to be clean as well as the inside of the needle. I would then put a "kit" in the carb, adjust the float, put it back together and adjust it as the manual suggests.

Not everyone will agree but I would then time the engine as shown in the tech section here on OCC.

Once running, final adjust the carb according to the manual.

If you feel that the engine is running hot, I would also clean the mouse nests out of the flywheel shroud and engine block cooling fins.

While you're under the hood, also look at the forward side of the engine and see if there appears to be any oily residue coming from in between the cylinder head and the block, it may be time for a new head gasket and to de-carbon the top of the engine and under side of the head. Once clean, sand the head flat (as described in the tech section). A warped head will not seal up and the engine won't run well.

My Brother has been using my 105 for a couple of years now and he just loves it. It is one UGLY machine but it really runs, drives and cuts great.

Thanks for all the information. I'll start by taking apart the carb and soaking it, plus rebuilding it. I've been looking around for a rebuild kit but I can't seem to find one. The carb has two sets of numbers on it one is C-236315 and the other is 235058. None of those return any results for a rebuild kit as far as I've searched. Do you know where I could find a kit for this carb? I'll also take a look to see if the head gasket is leaking, it probably is as the entire block is covered in dried out grease/oil. Again thanks for all the help, I'm looking forward to getting this thing running right soon.

Thanks for all the help guys, I'm gonna clean the carb and rebuild it. I'll keep you all updated as I work on the tractor. Again, thanks.

Carb Kits AND the two carburetor gaskets here, https://www.facebook.com/CubCadetand...49696141763776

I'll have to look, I may be sold out, if you want one PM me, and I'll get some more, usually only takes a day or two.

So I've got an update, I cleaned the carb today and made sure all of the holes were clear. I put it all back together and set the high speed needle at 2 turns and the idle speed at 2 1/2 turns and tried to start the cub, but no luck. It cranks, and smells like gas, but wont start at all now. I looked at the points and didn't see a spark so I'm going to attempt to set the timing in the next few days.

You might try running a jumper wire from Battery + to Coil +. Then use your 12V test light from ground to Coil -. While cranking the engine, watch the light to see if it goes on and off. Try this with the jumper wire off too.

I adjusted the points to .020 per the instructions in the technical section, and still nothing. I also ran a jumper cable from battery + to coil + and used a multimeter at coil - and I got 0 volts while cranking. I also used the multimeter at the battery, at the regulator and at the coil +. At all areas I was getting 12v even at the points I was getting 10 v while cranking. Any ideas why it's not starting? I also noticed white puffs from the exhaust while cranking, is that a sign of anything? Would cranking the engine with the battery hooked up reverse polarity damage anything?
