Am I getting full rack travel?
« on: April 14, 2018, 02:03:36 AM »
Greetings all.
My engine seemed to be lacking power and I was having binding issues with the governor linkage anyway, so I decided to try replacing the yoke as per pictures I've seen here.
During this process I realized that the rack is not opening fully once all of the linkages are connected and adjusted per 38AC's method and I tighten the spring which opens the rack.
There is no external binding and everything is moving smoothly now, but about 60% rack is all I get before I can feel the internal governor sleeve reach it's full travel, so no matter how tight I make the spring the rack will open no further.
I have attached 3 pictures showing the rack in the No Fuel Position, Fully Open with the linkages attached but held open against the Governor Sleeve, and 100% open with the Vertical Linkage disconnected.
Does this seem normal?

Yup that all you get with the CS governor and more than you need. The original design actually  used a rack limiter to further limit the travel except when starting, something India chose to dispense  with

Thank you very much sir.
That's one more issue solved. I'm moving on to the next one: fitting the gibb keys :)

I did something similar with my injector pumps. I used Chinese rod ends from eBay to complete the linkage. Works perfectly.
