OK so I just put my new cam in, (lifters springs etc..) everything else the same and fired up the motor...
Started fine.. Idles fine... won't go over 5000 rpm...??
Flywheel key is good, checked timing with degree wheel and light... OK
Spark Good, Ran carb adjuster in and out gets better but not much over 5k...
Compression good, leakdown good...
When it cools down I'll recheck valve lash, might be on tight side, does that sound like the problem, or should I look elsewhere..?
Not valve lash, rechecked adjusted "slightly" but no improvement..
I'm going to try a new plug, although this one looks to spark fine...
