    Manco Go Kart Model Numbers & Names

    Copy/pasted from the web: https://www.gokartsupply.com/mancogokarts.htm Just in case the link ever goes ‘404’ Use it to cross reference your kart name and/or the model number for ID purposes.

    Spark Plug Condition Charts

    Color charts for reading your plugs. Many such charts out there and as old as time. I think they mostly agree with each other but best to check and compare. Lead fouling? No joke. They still sell leaded gasoline. 😉 Spark plugs last a long time, tens of thousands of miles in automotive...

    How to Prep Azusa Tri-Star Wheels

    ... for Aircraft Go-kart and Minibike use. So Azusa Tri-Star aluminum wheels aren’t perfect from the factory....(oh dear). Most would argue that it doesn’t matter and they are good enough for fun kart/minibike use especially in lieu of the way they are used off-road or on rough surfaces, and...

    Briggs & Stratton Single Cylinder OHV Air-Cooled Engine Service Manual 276781

    Otherwise known as Briggs & Stratton Coffeemaker 270962 User Guide. 🙄 I think this manual deals primarily with the Intek series but it might apply to their China engines. Link only (for now), although you can download it there (archive.org). I have not downloaded anything from there before...

    Airheart - Thomas - Comet - Rotary - Mechanical Brakes

    Among other brands. All of these mechanical brake calipers are the same, or nearly the same in operation. Can be used with nearly any diameter disc, but only up to 1/4" (6.35mm) thickness, which is why I didn't list any brake discs. Hurst / Airheart / Tolomatic MB-1 Thomas / Knott Mfg "400282"...

    An ID/info thread. Minat Inc. 115 East Front St. Annawan, IL 61234 Firm out of business U.S. Eagle Series - Eagle I and Eagle II These are some really obscure go karts. A few have turned up on the forum and of course no one knew the manufacturer. Easy to misidentify them as a Carter...

    Simplex / Valiant Manufacturing Co.

    Most of us have heard of the Simplex Challenger, a capable early race kart but if you had told me Simplex made fun karts as well (up to the 1970's it appears), I would not have known. Their motorcycle, mini bike and scooter models are perhaps better known...

    Air Compressor Stuff

    I have a Crapsman 3.5HP 25 gal air compressor that I use regularly but it's not as convenient as I'd like the way it is currently set up. I still have the 15 foot OEM air hose attached, so to air up car tires, for example I often unplug the compressor from the wall socket and wheel it out to the...

    Crankshaft adapters for useless tapered 4-strokes

    Interesting post over there on the Rear Engine Karts Forum, it’s a year old (Nov 2024) but the ebay search link still works. That’s a lot of product and honestly something I’d never have considered using, always thinking a tapered crank engine was a lost cause. All my engine finds have been so...
