Alright class racer mechanics. I need some help. I am down a cylinder. Nber 7 keeps fouling plug. I have changed plugs wire cap dist. I did a leak down got about 1 percent leakage. Compression is 165lbs all cylinders I pulled the intake and fitted it last night.
I connected a plug to wire and it is firing at the cylinder.
The cam loves and lifters are fine.

Any idea?? There is several of us scratching our heads on this one.

I put 170 lbs air straight to cylinder it ha no leakage out valves
