That there is a right and left spring is good news. I've always thought that one side seemed to not fit quite as well.

Thanks for checking into this. And, thanks to the McFarlane crew for the improvement.

Good Morning John,
Thank you for the inquiry on the springs. Yes, we now have a spring kit p/n 7140 that contains left and right springs. These are colored Red for L/H spring p/n 6822 and Blue for R/H p/n 7235 as seen below. The engineers have developed the new spring for the right side that helps align properly. I have attached the new instructions for installation of the springs for your reference. Our website does not have the new spring or kit listed yet, but they are available for sale. I am not sure if Vans has those yet or not? Hopefully that is helpful information. Please let me know if you have any questions.

They also sent an instruction on how to install, but I do not know how to post the pdf on VAF.
The installation instructions require ďRemove upper B throttle arm piece from the
carburetor shaft.Ē
New info.

Now Vanís themselves have designed theit own left and right springs (Vanís Part No SPRING-00002-L/R-1). They are not the same as the McFarlane ones Ben Strahm from McFarlane recommended above.
Vanís support emailed me
ĎThey are not the same springs (as the McFarlane Red for L/H spring Mc Farlane p/n 6822 and Blue for R/H McFarlane p/n 7235).
See section 50-05

From our SB 18-03-06:
NOTE: This spring design is supplied by Vanís Aircraft and
not available through McFarlane Aviation Products.

In the mean time, the unavailable status has been changed so there is a limited number of the current part # available from Van's for replacement parts.
Scott, I ordered Vanís springs, however I have a vernier throttle. Guess I have some extra springs now and must order McFarland springs errr Iím confused. Iím not a builder. Thank you!

The new spring from Van's, detailed in the Service Bulletin are designed to be used with the vernier throttle in place of the ones supplied by McFarlane

To be fully up to date, will I need a new cable, as well as the new springs?
Cheers

The new design springs should work with the original throttle control or the vernier.
