Mutunuc 61 i/c fuel intake nipple

[Den Moran]

I have a Mutunuc 61 engine with a Aeromaster bipe that I purchased recently. I am trying to get hold of a mutunuc seiki 65 ABC manual, but it's very like an ABC pattern, so I'm not too bothered if I can't find one. 

    I do have a problem with the fuel intake nipple, which 'presents' toward the prop, a bit too close for my comfort, and would like to replace it with a 90deg. one to carry the fuel tube around the corner and back to the tank at the rear of the engine. Does anyone know what size this 90deg. nipple is, or how can I find out, and who sells them? Thank you, Den Moran

Not an engine that I have any familiarity with but I suspect that the carburettor has been fitted reversed. Can you turn it 180 degrees and re-route the throttle linkage?

Sounds like carb has been turned 180 deg as all were supplied as per DW's pic . I've seen 90 degrees nipples ( fuel type )😉 in the past but don't know where you will find  one now , try ebay ?but you'll need to know the thread size.
