I honestly dont think its engine specific. Ive had many different brand engines and the needles all loosened up over time. Some faster than others but its nothing a cheap oring wont fix. The methyl Alcohol combined with the nitro methane tends to dry rubber out over time. Then combined with the vibration and dirt its a recipe for disaster or wear.... LOL Its nothing major at all in my eyes...

I know OS and Go engine carb high speed needle o-rings will fit too if you are in a pinch at a race. I used an old OS o-ring while at a race when my needle moved and then I replaced it with a new Go o-ring when I got home. But in my newest Arrow GTR I am using the stock o-rings. When I have time I'll pull them out and see if they are larger then before.

I was getting almost 12 minutes a tank with my Arrow at the ROAR Nats. After a 9 min practice heat, I had almost 1/4 of a tank left. I used a Mugen pipe with the 6.5mm reducer in my Agama A8. My tank was way undersize but the cylinder was not marked so I don't know by how much. Engine ran perfect and temped between 230-260'F.
