tried them at.60, put the o71s at the mo.I have checked timing,all the other gaps,fuel pressure,all seems spot on.When i floor it,i get the omph,then when it hits 15psi it sounds like a wet fart,the power just goes,it seems to get through it,but by then the power has gone.It hits about 25 psi by then.The afr looks good,at the brief time i get to look at it between 11-12.Looked in the dizzy,and you can see arching marks on the rotor arm,and on the 4 pick up points,looks a bit whitish too.The cap was new about 1200 miles ago.
