'73 tii Warm Up Regulator? Do I need a new one?

Do I need a new warm up regulator (behind the K-fischer pump)? Started car after changing throttle linkage (bought three piece set from Jack Fahuna, ready to install and lengths precisely set up), and did the book procedure on setting the air butterfly cam with the 4mm pin, and the hooked rod in the lower slot on the "bell crank" on the K-fisch. Car started but idle was fast, about 1800rpm. I figured the small butterfly adjustment screw was not right (idle mixture seemed rich), so started to turn it in a half turn, and the engine suddenly quit. Backed the mixture adjuster screw a bit, and tried to restart several times --- engine starts after long cranking, with foot at about half throttle it will fire, run a few seconds, and quit suddenly. When it first ran fast, on cold startup, the timing sounded reasonable, so I have the distributor set good for rough startup (wanted to get it running then fine tune the timing).

NOW I wonder if the warmup regulator might be sticking, causing the engine to quit after warming up for a few minutes. Any suggestions? What does the regulator cost? Good idea to just replace it, to eliminate the possibility of defective operation there? My "BMW" dealer here in Anchorage [Lincoln-Mercury dealer with BMW as a sideline picked up a few years back] shows the regulator priced at about $400+, special order. IS THAT RIGHT????

TIA, Eric (learning tii-self-reliance in the absence of tii-experienced shops in Anchorage).

you would know if your warm up regulator is

sticking. When the car is cold the big washer is in

contact with the lever, as the car warms up the big

washer moves up releasing the lever, at

temperature there should be a gap between

washer and lever. If the washer is moving but not

fully releasing the lever it can be adjusted to do so.

good luck

I confirmed $400 price with La Jolla Ind. -- he told me how to check and adjust also, but said I need to get the engine running and warmed up fully before setting fine adjust on the mixture. I suspect now a weak ignition coil, as I can't get it to fire well even with mixture screw where I started. Have a strong output coil on my '69 I will swap for test. What is best coil for tii?
