83/84 NH80 throttle needle vs. 85

Post by breaze »

Hi all, I've had several 83/84 NH80's and they all had to be feathered at WOT. I also had one 85 NH80 and it was significantly better. From what I've read, for 85 the throttle needle was changed to improve the situation. I am currently working on an 85 but I do not have the throttle needle for it - I do have a throttle needle for an 83/84 which I am planning to use but would prefer an 85 needle.
Do the throttle needles have codes which identify them? I've seen re-build kits which specify a D158 needle...
Are there any after-market means of getting an 85 NH80 needle?
