Honda GX200 18 LB Valve Spring -
Although this spring is not legal for the box stock classes, it offers another option for those looking for more rpms than offered by the OEM or 10.8lb springs. Can be used in the Honda/Clone and the NON HEMI Predator 212cc heads. Will not work in the Harbor Freight 212cc Hemi head. If using a cam with more than stock lift or rocker arms with more than 1:1 ratio coil bind must be checked.
*** ATTENTION ***
WILL NOT WORK IN THE HARBOR FREIGHT HEMI 212cc ENGINE.

I wanted stronger valve springs for my clone. These are just the ticket for my mildly modified engine with the stock cam.
After installation I was concerned about coil bind. It's close so I called ARC. Their how to video said there should be at least .060 between coils. I didn't have that. Jody promptly took my call. After listening to what mods I have done to my engine, he assured me that they would work with no coil bind with the STOCK cam. Engine runs great.
awesome springs , factory Honda packaging no more floating valves
Received my new springs the other day really like the recoil alot better than stock in every way I'm sure the valves will thank me in the long run
I am pleased with this spring or gave us another 1000 rpm.
