Even in neautral it hits a wall at 7000rpm and wont rev any higher,,,

i can turn the spring and i can push the retainer down,,, hard to gauge KG's though, will see if i can find a push scale, what i did do is check that i only have about 4mm from full open to valve bind...

Had somone helping changing my jets while i was playing under the valve cover, and yeah, in went the wrong air correctors and well, my Machined flat top mazda pistons took a break... blowing crank case vapour out like mad.

ehh, I killed the unkillable,,, funny that its a mazda part that failed lol
