Some advice re: 8 hp TB Chipper

We are moving and won't be taking my old 8 hp TB Super Tomahawk chipper/shredder (model 190412). I've been told that it needs a new carb. Otherwise it runs very well. Should I buy a replacement carb or just sell it as-is?

Why were you told it needs a new carb? Obviously a well running machine will be easier to sell and garner a better price than one that doesn't run or runs rough.

Unless the old carb is broken or damaged in some way the most common fault is dirty passages or jet.
I saw one simiar to yours on Ebay for an asking price of $600.00.
If this is what they are worth then it might be worth doing something with.

Here is a place to find a manual.

Thanks for the quick replies. What you say makes sense. I think I have the skills to swap in a replacement but I would not trust myself to take one apart, clean, and put back together. Do you think this is a good choice:https://smile.amazon.com/gp/product/...10_em_1p_0_im?

Personally I'd take apart and clean the one you got. It shouldn't be that complicated, just pay attention to how it's assembled. Worse case scenario you'd mess it up and then buy a new carb.

I agree.
Take your DIY to the next level.....you don't have much to loose.

Use a clean workbench space, a small tray to hold parts and purchase a can of carb cleaner.
If you have an air compressor that would help but is not totally necessary.

There really aren't many pieces to a carb and they are pretty simple.
Take a couple of clear pictures of how the linkage is connected to the carb to make reassembly go smoother.

There will be a of videos online to see what is involved.

If your willing to buy a new carb. you've got nothing to loose disassembling and cleaning the old one. Use your phone or digital camera to take photos at each step in the disassembly to help you when it's time to put it back together. Even if you don't fix it you'll learn something and odds are good that you can fix it. Worst case you can fall back on plan B and buy a new carb.

I would question why you would need carb work if it's running well. I'd be inclined to sell it as is. As a rule nothing is simple anyway and it may not work as well after you've worked on it.

Geeze!
I just now noticed this comment.
I've been told that it needs a new carb. Otherwise it runs very well.
What does this mean?
Did a person that wants to buy the chipper say this.

So it runs and runs well?
Why would you replace the carb?

Greg, yeah that was unclear. It WAS running well until one day it would start but then die. A friend played with it a bit and told me the carb was gummed up. I had never had it cleaned and always left gas in it over winter. Made sense to me. I any event, on your collective recommendation I took the carb off, took it apart and cleaned it. Only misplaced one machine screw. Some adjustments and it starts and runs better than it has in a while. Thanks!!

Good to know an old dog can learn something new.

I'd put some Sea Foam in it, should help clean out anything still in there.

Back again. Got it started and chipped some. After about 20 minutes it started acting up. Specifically, it would kind of throttle down, then rev back up then down again. Under load, when it was chipping it would rev up. Never would get to full throttle. This engine does not have a fuel filter. Any ideas?

A suggestion would be to take it apart and clean it again.
It is possible that there might be small dirt particles in the fuel tank.
Shining a light into a nearly open tank sometimes shows particles in the fuel.

Using the best grade of premium fuel you can get would go a long way towards preventing future problems.

Might make sure the oil level is not overfull, and contaminated with fuel. That can cause those symptoms as well.
