So Gents,

Chuck has a little problem with trouble shooting. Does not have it all very well organized I think.

While we are all waiting for the moment he does find his adaptor back and after that we all can look for a needle valve it was a good case already do some investigation how big the problem really is.

Do we have to look for a OPS 60 (and of course no 61!!!) Red Head rear exhaust (1) and rear carb needle or needle valve? (Chuck?)
Or can we look for a needle of an OPS RC 10 front carb and side exhaust (2)?

Or

Do we have other possibilities in the future, for example the needle valve of an OPS 40 side exhaust (3)?

The answers is, “Yes, yes, yes!”

If the carb is the same of a (2) engine than also a (3) engine needle probably will fit, see my picture.

So we are all waiting for Chuck, with his OPS powered Mississippi Queen with belt drive!!

His OPS powered Mississippi Queen with belt drive??

Yes because I am also looking for the reason why he did call it a side exhaust engine!
He probably will call a pusher engine a front exhaust.

Chuck, it’s all fun and we are waiting, or do we have to look for an adaptor.
