Replace or Rebuild Comet 20 TC

[akitchell]

I recently purchased a gokart off CL. After stripping everything down, I found several issues with the TC. It's a comet 20 and I am trying to decide if I should purchase replacement parts for those that are damaged or purchase a new TC. If it would be better to purchase a new TC, what recommendations do you have?

Parts w/ Issues (see pictures):
Shoe driver assembly
Sprocket
Hub driver
Driver drum

I could be wrong ,but that looks more like a 30 series with the flat back shieve. From the looks of the wear on that thing I myself would replace rather than repair, it seems everything is worn on that sucker.

If you are going by the '20' on the driven hub, that refers to the ramp angle and not the series of the TAV.

Correct

I thought it was a 20 based on the driven hub as per the attached picture. Thanks for setting me on the right track. This is my first go kart.

Do you have a suggestion of a good replacement that won't break the bank?

If replacement parts cost more than $75 with shipping, then just buy a new 30 series on ebay. They are about $75 with free shipping. Here is an example: http://www.ebay.com/itm/131557199500?_trksid=p2055119.m1438.l2649&ssPageName=STRK:MEBIDX:IT Just make sure and find one with the correct sprocket for your application.

Thanks! I currently have a 420 chain. Is there any reason to change to a different chain size?

Bigger chain = stronger. I would stick with the 420 (which is a common motorcycle size) rather than go backwards to #35
