Cogging, rather blackouts of the engine

L Karl.Your choke wire should be hooked to the STATOR output on your alternator.

I now got this distributor http://cgi.ebay.com/ebaymotors/Distribu ... 0216826675
It is past 68 and my carb is from 64, so it already has centrifugal advance and not just vacuum advance. This is just what the carb needs.

Can this little thing like the electric choke mounting on the coil cause this problem?

have you checked your plug wires with an ohm meter? i've had cars that will miss under load with bad wires.


and...

why are you so against the dsII upgrade?

 

[woodbutcher]

L.Karl.Yes it might.

Karl,

If the distributor you have has mech advance then disregard what I said.

Loss of power on accleration could be attributed to the accelerator pump, a lean condition in general, or to a timing problem.

Too advanced of ignition timing can cause this problem.

@grocery getter
I haven´t checked them with an ohm meter yet but today I´ll be heading to a meeting where I might be able to get some original wires and test them.

@woodbutcher
I´ll try that aswell.

@Bort62
The accelerator pump gives me two streams that look as if they were normal and strong enough.
CO is at 4% at 700 rpm

But what you say about timing.
I got it at 9-10 degrees in fast idle.
The engine has these bumps at 1500-1900 rpm when idling there. Any 2-3 seconds it sort of bumps a little. When I unplug the vacuum this stops.
but when I dirve it without the vacuum line it is as bad as before.

One more thing that I watched. my spark plugs are black. they should be red-brown. This might be a bad ignition since the fuel mixture seems to be ok (btw my carb is frm 64 with 1.02 venturis)

yours sincerely, LKarl

I'd be suspecting a power valve from what you describe now. Have you monitored the vacuum at the different points?

I don't believe timing will cause the plugs to look like you're running overrich.

One other thing to eliminate from the equation is the PCV valve. A clogged PCV valve will give you a rich mixture. One of our members found it was causing problems with his HW jetting, which were resolved when he got a new valve.

Thanks a lot for this tip with the PCV Valve.
I found someone else with sort of the same problem and he just forgot to plug the vacuum line to the PCV Valve back into the Carb. So I could help him.

There´s one more thing that I gotta tell you that I recognized with my PCV Valve.
The Vacuum Line that goes there is connected to a split. So the Vacuum comes from the intake and then is splitted to the power brake (which I built in) and also goes to the PCV Valve.
Today I connected the airfilter with the PCV Valve and the Power Brake solely with the intake. Tomorrow I´ll try it because I didn´t really have time to.
I´ll report then but maybe that was the problem.

yours, L.Karl
