are you nuttered yet?
the emissions computer controls your timing still if your not
and seeing how you have disconected a bunch of things that relate to the carter feed back carb this could be part of your problem.

Well, life has gotten in the way of late. Haven't had much time to work on her. I will update once I get a solution.

Alright, got some time this weekend and found a bind in the throttle linkage. Seems to have fixed the problem. Now, I just have to get a vacuum gauge so I can tune it.

The HEI install is now on deck. I decided the next project should be a fun one, (Had enough frustration with this one) so I decided to install my LED tail lights. Looking good so far.

I really went with a minimal approach. All vacuum lines are gone with the exception of the vacuum advance on the distributor, and the PCV lines.

Here are some pics of my progress:








She is running good so far. Hell, she stays running at idle. That in itself is an improvement. I still have to adjust the timing and tune the carb and then do a road test, but I am happy so far.

If you have any specific questions once you start, just holler. I will do my best to answer questions and there are a few guys on the board here who are very helpful and have done this swap.

well moose how is it?
I have a HEI kit coming next week.
time to get rid of more wires!
tear the 2 computers and wires and looms.
TFI was good but just doesn't seem great I have a stumble at cruising in 5th with little power and when I adjust the timing to get the top end power back I get a lot of pre-ingniton spark knock so the HEI kit I ordered has adjustable vacuum advance built into it.
cheers

Quick question....

What port on the carb did you run to the vacuum for the front axle disconnect?

Thanks!

manifold vacuum

off the intake manifold

if you run ported then at wide open throttle there is a chance that your axle will disconnect.

the intake manifold vacuum ports is that cluster of 5 right beneath the carb, correct?

Just an update:

Had her out wheeling at Rausch this past weekend and had a great time! The carb performed flawlessly even on steep inclines. Couldn't ask for anything more. Can wait to get the HEI installed for some more power. That would be my only complaint, it needs more power, but I may be able to attain this with some more tweaking and the HEI.

As a side note, the manual choke is a nice addition and doubles as auto throttle quite nicely.

Hoping to start the HEI soon.

YA got my mc2150 working dreat and my HEI works good now too, manual choke is nice I like it. I will be adding a hand throttle though. just another item I have found that I could use in some situations to keep the revs up and to prevent having to turn the key and able to brake and clutch and move forward all in one shot would be worth it to have.

Hand throttle is still in my future as well.... just nice to be able to use the choke as well to keep the revs up.
