Start searching the Fourm for properly hooking up the electric choke through a oil pressure switch.

That electric choke will draw a constant 5 or so amps.

The ignition wiring is crappy at best. I don't know if putting a electric choke on the ignition circuit of something that wasn't sized for it if it will cause problems. Its easy to use the ignition circuit to energize a relay. And then use that relay to power the choke.

Also a good point. I was thinking to run it from the ignition, where my distributor lead is coming from.
I think I may actually wire in some sort of power and ground bars in the engine bay for all of these things that suddenly need power. First things first, get this sucker mounted and running.

Once you have your new carb up and running can you post an impression of how it's working for you. I've looked at getting a rebuilt 2150 from National Carbs and am interested in other people's experiances with them.

Thanks

As far as the "Harley" breather is concerned, any FLAPS will have a similar 1.5" round filter. Usually cloth, K&N style. http://www.jpcycles.com/product/4300150
Is this what you had in mind 86cj74.2L? If so, I gave ya a thumbs up! Plus it's chrome! It is an aftermarket bit, so if you call a few Harley/ATV/Import shops etc, they may have one hanging on the wall for $20. Could have ya up & running today. Saturday is busy, so get to dialing!

I've also learned that sometimes... when people don't agree with you .... its best to hold them down and kidney punch them till they agree with you

I paid a lot less than 20 for the breather on the sporty. Didn't say HD either.......

But yes that type is what I had in mind.

Ok, got it connected and it fired right up. However it's running rich as all get out.
The mixture screws were 6-1/4 and 6-3/4 out from the shop, so I dialed them in to 3 out. I tried the mixture tuning trick of starting at 2.5 turns out and working them in till the idle went rough, then 3/4 out, but 3 seems to be where I end up anyway.

Still running rich and backfires through the carb if I let it idle the hit the gas.

A couple things here; My choke doesn't seem to be working at all. It just takes a 12v lead, right? I'm wondering if I don't need a male:male adaptor to connect it to the heater tube? I know you said that I can just plug that port, which I did, but curious why the butterflies aren't opening.

Second question; Do I need to plug the power valve into a vacuum? My old carb AL-2100 doesn't have that port. Could that be causing it to run rich?

Ok, the backfire was timing. Fixed that, and plugged the vacuum advance into the carb base rather than the manifold. I know that they say to plug it into the manifold for an HEI setup, but I couldn't get the idle down that way.

The choke still doesn't seem like it's working, though.
Also, question still stands on the power valve.

I'm thinking the reason it seems to run rich is b\c I have NO emissions stuff connected whatsoever. That's another project in itself.

All in all, though it runs much better than it has since I've had it.

Seems I'm still battling a timing issue. I took it for a test run yesterday and it ran better than ever. Let it sit for 10 minutes, then went for another drive and had a bad miss. Can't nail this down.

My only thought are the plus are gapped at .050, per hei recommendations. Too wide?

Where are you getting the power for your choke? It should only get power when the key is in the on position.

Gasket Stacking

On my J20..it is as follows for gaskets under carb... Thin gasket on intake, Hard plastic spacer/heat shield, then thick gasket, then carb. Hope that gets you going.
