I inherited or borrowed a go-kart from my brother in law and I was looking for some cheap, easy performance tips to get the most out of the engine. (Motor is probobly a 3.5 Brigs).
cheap header-3/4" pipe out of the exhaust flange. will make it loud, but adds a good bit of low-end to it.
if its not already done, disconnect the governor to it and let it rip. go straight from the top butterfly on the carb. cometkartsales.com has a kit for mounting it this way.
If its a briggs you can advance the timing one to 7 degrees for a buck fifty id try a 2 degree offset flywheel key. dont want to over do it. its a bit of a guessing game but cheep.
