318 Idle issues
Not the best when cold. I have to try to figure some things out with this carb, or try a new one.
When I first started working on this the choke thermostat was not hooked up inside the housing. I fixed that and just set the choke in the middle setting to start.
We also noticed the T slots were overly exposed from what I had read. I closed those down but when you set the fast idle screw it always opens those too much, and never lets the blades close back to where you had the T slots set. I have never set one up so I am not sure why that is happening.
If using the choke, the choke thermostat needs to be set stone cold, very first thing in morn, or similar. With the spring properly on the choke pin, rotate the cap till the valve just closes, secure it there for now.
It should choke properly and fall off fast idle with tap of gas pedal, some screw adj may be nec.
Choke should be full off warm, no choke interference.
If you can't get the t-slot right, and idle mixture screws have no authority, you may have to open the secondary a bit, there's a stop screw to be reached from underneath, on pass side, that should allow you to close the primary to get slots where they should be, mixture screws should work .
RRR prob covered all that, I missed a lot in between, sorry.
Good luck.
Cheers
