What does a slight 'fuel ring' at the porcelain top mean?
Usually I'll see it at the porcelain's base.
Installed my 850 vc...the engine seems to really like it vs the 850-annular dp that came off.
Proper secondary spring is in, they start kicking in a 4k and do so smoothly/no stumble
Still tweaking jetting, may be a hair rich.
