I am planning making up a 4 carbs in a row for a Merc 44 with left over OMC 3 holer carbs dumping into pyramidal reeds system. All these carbs have fixed jets. Does anyone have any experience converting them to high speed needle adjustment?

[Fast Fred]

? spose ya could pull the main jet out and make it into a seat, then use a needle
screw in place of the drain plug that should do it for ya.

Thanks Fred: Last year I purchased a new 3 Holer 49 cube OMC long block at a garage sale for $200.00 and it came with lots of extras from another one that wore out, so I made up that 3 holer for racing SE but with it I left the carbs intact with fixed jets. Since I landed a 4 carb specialty case for Merc 4 cylinder where 4 carbs could be mounted and hearing that these carbs might be tuned better with a high speed needle came the notion I sould ask because I have no experience with these OMC carbs at all other than from people using them on B1s and trying them out on the OMC 35s. Thanks for the advice, I will sure look at that real hard now.

Only seein a few differences between the cases, is one better than the other?

[Fast Fred]

Boatnut is one better than the other?

not sure, the solid mold is nice and smooth in the ports, No glue lines, seems that it moves more water through the case, lookin at divider.
