Default OS 7D Carb.



Hi there,

I have a OS 90 FSR with the 7D carb, i need to buy a new
needle valve o ring but can't find the one i need.
its quite flat and a greenish colour
The needle does not have the grub screw in it like the
ones i have seen while looking for part
like the ones for the 108 fsr.
Are those needles interchangeable so i could just replace needle i have
with one of those.

Thanks.

Default RE: OS 7D Carb.

If the needle will screw into the engine, it should work. The main difference would be the small pointy part. That is of different sizes and tapers for the different carbs. The main difference in operation would be the number of turns needed to properly-lean the engine. Also, some will be more sensitive to adjustment than others.

Here's the o-ring: OSMG7388 24981837 O-RING NDL FS/FX/LA US$4.99

These parts can be ordered through any hobby retailer who sells O.S. Max engines and accessories.
