I need your help, i have some many questions...
I make a new engine with a ISKENDERIAN regrind A12 cam, twin carbs, double springs, an A14 cylinder head on A12 eNGINE and it works well in a couple of minutes, after that it looses power, and the valves gains clearnces, after a while i had adjust them and new clearance, in a couple of minute a total clearance 0.70mm. I dismantle the engine and i found the original rocker arms valve opener has wear, loose material, the regrind cam have only shadows i think its ok, but im afraid it gains wear. Please let me know install normal a14 Valve Springs? Buy a reforced rocker arms ? Double springs can make this? Lack of oil on cylinder head?
A12 actual cam performance is: WITH THE ISKENDERIAN GRIND
