Opinion on this Spark plug reading.

Made some progress this afternoon. Like YR and others have stated.. Hooked the vacuum gauge up to the manifold and checked it at cruising speed. Had close to 12hg. Went and purchased a 10.5pv and installed it after dinner. WoW it's much crisper than before and pulls hard. Tip in is crispy. Going to pick up some new plugs tomorrow and do a pull and see where I am at. Also like indicated before, going to bump up the initial 2* and see were it falls on the ground strap. Then hopefully start trying to lean out the top.

Woodie
