From what I have read the stock springs are 12lbs. These look almost identical but they do have slightly larger wire and feel a little more stiff than my stock springs with 20 hours. Removed governor on my predator 212 and installed these with a flat top piston and bullet wheel and rod. Doesn’t seem to rev much higher than stock but has eliminated some clattering sound at high rpm’s. Unfortunately I don’t have the tools to actually measure the spring constant.

These springs seem to be quite a bit stronger, they are taller. So far so good.

I bought 2 sets of these 22 LB springs for a Honda GX200 and Predator 212. Both sets worked perfectly and got rid of the floating valves at high RPM due to removing the governor. I’m actually going to order a few more sets since I restore go karts and build engines. If you add slide carburetor with adapter , rejet it, headed pipe and remove the governor and add these springs. You’re definitely going to have to hold onto the steering wheel.I highly recommend these 22 LB springs and for the $10 price with free shipping you can’t beat it!

I replaced the stock 11lb valve springs in my Coleman ct200ex with these 22lb springs. Now it is much smoother at higher rpm (gov. Screw adjusted also)
