Fuel Union Or Nipple Required For Aftermarket Carburetter On An OS 48 Surpass.

[David Davis]

I have an OS 48 Surpass fitted with a twin needle aftermarket carburetter probably from an SC/ASP 52. I bought it second hand. Recently it has not been running reliably. The president of my club suggested that there may be dirt in the carburetter and in an attempt to be helpful he tried unscrewing the fuel tube union/nipple. He only succeeded in snapping it off! Fortunately one of our other members is a retired maritime engineer and he managed to remove the remains. We discovered that the thread in the caburetter is M3. I sent off for another part which was advertised as 3mm but as it was a Du Bro product it turned out to have an American thread.

 

I will try contacting Just Engines to see whether they have anything suitable, but do you know of any other suppliers who might have a suitable part?

Only a thought - is a silencer pressure nipple the same size ?

It is as you say ACE

A 3mm silencer nipple will do the same job

David,

I bought some recently from model fixings, no confusion on thread types here...
