I’ve got this Honda GX270 (9hp) that will be getting dropped into (along with a 40 series torque converter) a Yerfdog Spiderbox or some other 2 person full suspension kart running on 12” fancy golf cart wheels with 19-20” turf tires. I’m perfectly capable of doing the work as long as I start with the correct plan. So I’d like to add electric start to the engine with charging as well. The problem lies in that no one makes a billet flywheel for that purpose (ARC said there’s no demand). SO
1) If I leave the engine completely stock with the govt. still working how fast will this 9hp engine push the kart?
2) Would a stage 2 kit (390 carb, cam, billet rod, HP springs, stainless valves, and maybe porting the heads) make any difference (even for low end torque) if I don’t eliminate the governor (since a billet flywheel isn’t available)?
