Anyone have the ability to look up the correct fuel bowl vent jet diameter I need for an '88 Mercury Blackmax V-200? Serial number is B264174. I'm looking for cylinder 1&2 but if you have it and could post all six so I could confirm what is in the rest I would appreciate it very much. TIA

Search for the repair AND parts list for this engine. Mine lists the the jet/vent sizes for close / related block hp main jets and vents Including altitude corrected jet sizes.

What WH series number carbs do you have? Also these are staggered and not all carbs get one, if I remember there is only 4 jets used...

Thanks guys. I don't have it in front of me but WH-4 is what comes to mind. I'll confirm when I get back to it. It only has 4 in it now but placement may be an issue with whomever did a rebuild prior to me. The only reference I have doesn't cover my serial number and the parts finder shows 2 per with no placement reference. .084 and .096. I only have .096's

I was mistaken. Not sure where a got the " 4" from in wh-4. Probably reading someone else's thread. Mine do not have a number after the " WH". All three are the same. They are on a 200.
