Choke (fuel enrichment) screw up?

Post by acurtis » Sun Apr 05, 2020 1:25 pm

So I have been working on getting my 73 710 back on the road after years of sitting- so went through the "red death", then added the solid state ignition module, then rebuilt the carbs, replaced one shut off solenoid. The problem is i think I messed up the chokes when i put them back together. Initially i thought it was a float height problem (yes, on the list)
It starts up, but idles crazy fast with choke off, when i open the choke it slows a little, but still way to fast, It also sputters when when you give it some gas. I'm getting ready to open up the chokes and look- (I assume I put them in both the same way)Is it possible to put the plates in backwards or upside down or just "in wrong".
so................... looking for any guidance on the set up.

Yes, you can put put the fuel enrichment plate in wrong. If you look at the plate side, in the center is a half round proud section of the round pivot. If you look at the carb side, there is a V depression in the center. This allow the plate to only rotate less than 25 degrees of rotation.

A close but a little off topic problem. The nut holding the fuel enrichment plate frequently comes loose on my front carburetor. You can imagine the result. Is there any predisposing reason for this to occur and is it ok to add a little thread locker? Thanks all!

The nut you're referring to is indicated by the red arrow if I understand correctly.

I've used a lock washer and had good results. You could also use a distorted-thread nut if you prefer. I don't see a problem with using thread locker either.
