Main jet locations? Why am I missing 2 of them?

[outamymind]

OC272926 1990 200hp v-6 everything has been removed....oil injection, voltage regulator, spark advance. I have noticed I am missing 2 main .096 jets. Is this the reason it runs rich between above idle in forward till on plane? Smokes pretty good at that speed. Cruising speed or WOT there is no smoking and runs great. If it is supposed to only have 4 instead of 6 what are the correct locations for them? Any idea why it doesn't like slower speeds?

those are "vent jets" not uncommon ta only have 2 or 4 or none at all... your ok........

What would cause the smoking/rich condition when I want to go slow? If I start it up and shift forward...at an idle its fine. A slight increase in rpms and it smokes like crazy. Whack the throttle and no more smoke. Keep cruising no smoke. All the jets are correct numbers. Should I be looking at something else?

Does it run rough at the speed it smokes alot? Running pre-mix will cause more smoke than normal.

Yes it does but I don't let it get too loaded up. I increase the throttle and once on plane smoking is gone. Kind of frustrating that it cant be used at that speed. I have the premix @ 40 to one and use a TCW3 oil.....I'm pretty fussy on fuel and mix. Runs super clean at cruise to wide open. I thought missing vent jets could have been the cause
