OS 1.40 Needle Valves

[Keith Hoard]

Thanks, guys.

 

While I was swapping out an engine today, I noticed that the new engine was
using the shorter needle valve.  I'll try the longer needle. . .

I found the longer one worked much better also.

Welp having played with both, the sharper one is the one to use. It makes
the adjustment very broad compared to the stubby one. Also it may just be
me, but it seemed richer in the transition with the stubbier one. 

 

I'm sure someone else has a better explaination, but that's the one that
seems to work best for me. Engine gurus chime in. But use the sharper one =)

What is the (operational) difference between the two needle valves that come
with an OS 1.40 RX motor?  Thanks!!

 

(I know one is sharper than the other. . . .)
