PCV on MC2100

I've been doing a search on where to connect the PCV hose to my MC2100. I have been finding that there is not a manfiold vac fitting on carbs from vehicles before a certain year. Not sure what vehicle mine came out of as it was laying around a junkyard. All I really looked for was 1.08 and motorcraft stamped on it. It doesnt appear that the carb I got has a manifold vac fitting. Anyone know of any base adapters that have a spot for manifold vac, or do I gotta make my own? Also, I've noticed that my MC2100 does not have a "modulator diaphram" on the top half of it, or even a spot for one to be installed. Do I need this? It seems that it would just control the top plates...the throttle shaft seems to take over this action on mine. Did I just grab the wrong carb all together? Thanks
Tim

Re: PCV on MC2100

88 YJ 4.2 new HEI module, TFI cap/base etc., MC2100. I think the float on the carb is set a little high. it will flood when revved multiple times, and engine dies. I'll have to look at proper procedures for adjustin the mixture screws. timings at 8. Another thing, is it normal for a click to be coming out of the distributor? Not like an electrical spark sound. Just somewhat of a click that can be heard over the sound of the engine. Thanks

Re: PCV on MC2100

Ya absolutely. I opened it up and the magnetic pickup(is that correct?) is pretty loose and whenever the shaft spins, I assume it hits the pick up. But it definately is coming from the dizzy. Anything I can do to remedy this?

Yep, a rebuilt distributor, or new bearings for the dist. shaft. A rebuilt distributor would likely be less expenesive.

Huh?

I only said that because once I rebuilt a FOMOCO distributor, new sensor, new bearings and a seal. When I was done the cost was $2 over a totally rebuilt distributor with a new sensor already mounted.
