Bringing my 250 NC M3 back into action

Postby Bevel bob » Thu Dec 18, 2025 11:12 am

Not rode it for a couple of years , and last time it was not happy (kept spitting back and stalling ) , so as part of the process i will raise the fuel level a smidgin and enrich the tickover a tad . Cant for the life of me remember whether the pilot screw is in or out to richen on an SSI29D ! The blurb in the Dellorto literature is pretty vague too.

As no one seems to know! i checked and on ssi up to 30 mm the mixture screw is the same as a monoblock in is richer. Over 29 mm its the opposite .
