    Wanted: Briggs 5hp Flathead Cam

    All the spare cams I have require lifter bore reinforcement, definitely not mild. But dyno cams have plenty of options starting at $60, all you have to do is sent them a servicable core and they can help you out for under your $100 budget. https://www.dynocams.com/category/fh-stock/fham-cams/

    Honda GC160 Help with throttle

    Fixed speed engines and those that have throttle control operate the same way and use the same components. Fixed speed the governer spring is hooked to a fixed point to set a constant RPM. Bending this tab adjusts the set speed. On a small engine with throttle control, instead of the spring...

    Gokart belt

    From what ive seen the standard 203589a belt should do. Just to confirm, measure the distance from the center of the motor's shaft to the center of the driven/ rear clutch shaft. If it measures 7in or 1/16 less, than the #203589a is for sure what you need. Here is an example, buy from...

    Stopping oil loss through breather

    Even easier, since you do not care about contaminants entering your engine, keep the gutted valve cover, attach a hose and run it upward. Any blowby will run back down, problem solved.

    Stopping oil loss through breather

    Yep you got it. Reed valve in the cover you had to add back in becomes unnecessary when you plumb the vent into the air filter.

    Stopping oil loss through breather

    I got the same, the cast steel forged older style are much stronger than the stamped steel new ones. This was my first attempt at PCV with an automotive valve, had to add a cutoff valve partially open to prevent it from directly sucking in crankcase oil.

    Questions about tires, 13"?

    Trying to find taller than 11" with 5in rims is a challenge. Is the lug pattern standard? Installing a set of 6in split rims would open alot of options. Heres an idea... https://www.northerntool.com/shop/tools/product_200268374_200268374

    60's Simplex Challenger resurrection

    Finally did something with it. Since this is a quite rough example, I decided to keep the west bend for a better condition vintage kart or rokon. Slapped on a flathead briggs with horstman high duration cam, heavy valve springs with billet retainers/ split keepers, adjustable lifters, raptor...

    Tecumseh 10hp manco dingo help

    In the picture in post #17, the last pic you posted the cable is pulling the throttle control plate to half throttle. Refer to post #16. If it still runs wide open , the governer could be busted in the motor from the spring installed forcing it the wrong way, or the governer arm could have...

    Tecumseh 10hp manco dingo help

    Yep that "left spring" is the return. So if the cable returns with that spring, throw the one I said to remove away, if not install like my picture depicts. Put the cart on jackstands and start the motor.

    Tecumseh 10hp manco dingo help

    Your welcome, I hope this pic clears it up. When the engine is not running, the governer should be holding the throttle flap on the carb open to help the engine start. Once the engine starts, the governer will pull the carb back to idle or whenever rpm based on where the cable is pulling on...

    Tecumseh 10hp manco dingo help

    In the picture on post 5, the throttle return spring is in the wrong place. It is pulling directly against the governer arm, limiting the RPM's of the engine. Yes the adjustment screw I was talking about is present on your throttle plate, but said spring is directly counteracting it. The...

    Which replacement garter spring should I get for a go kart with a Briggs and Stratton 133432 engine?

    2200-2300 is what ya need. So you can keep the die cast aluminum weights , and run the orange springs.
