Mcfarlane throttle

[Hockeystud87]

I'm about to purchase the McFarland throttle to replace my old 92 kitfox 4 speedster throttle vernier with the threaded rod and small steel ball on the inside.

Running a 912 UL

Is this the correct part? Anything else I need to get for this to work?

That part number has cable ends.



The cable ends go into the bing 64 carb throttle arm cable bolt attachment.

And the 4' cable length is the appropriate size?

Currently I have the button but I have not used it a ton. The McFarland uses a friction lock with no button correct?

There should be no issues with throttle creep or anything like that with the McFarland correct?

My current one holds well just getting it initially set is frustrating if I move the throttle with the button.

i used the button all the time on the old throttle and liked it. with the mcfarlane the vernier only works if the push function is locked tight. the friction can also be light enough to allow both push and vernier but there is the risk that during a power reduction with the vernier that the friction will be removed to where the throttle will go to wot on its own. some thing to get used to

Well damn, that would be an interesting discovery should that play out on my first test flight! Thanks for that heads up.

Having the throttled locked tight sounds like a scary way to have a throttle setup. I would assume the vernier is really only used in cruise then.

Is this because of the 'pull' of the carburettor springs? In other words, would this happen with a 912iS, which don't have carburettors?

Yup, 912iS also has a WOT setting with a spring should the cable/connection fail.
