Hello all,
I was hoping someone could confirm the compression test adapter size to use for a compression test on my stock 99' rio red cobra. I bought the harbor freight compression test kit, and it came with a M10, M12, M14, and an M18 male with o-ring. Of course it didn't come with the M16 adapter which i'm thinking is the one I need, but could anyone please confirm the exact size that I need?
Thank you all in advance for your help
