sluggish at higher rpms

[jawn101]

Actually the dwell should be a steady 50 to 60 Cold (<60F) and fluctuating between 35 and 45 when warmed up.
There are several other dwell tests you should perform listed in the WS manual, D:04:15

Thanks for the correction Ron!

Thanks Ron. I was going to use the timing light to check the timing adv but my light wasn't working so ill get another one this weekend. Timing adv and mixture were the first things that came to my head when I felt this problem.

NP!

Just remember to set the CO absolutely last if you have to adjust it....

Are you supposed to turn the mixture screw when the engine is cold? My cold dwell reading is at around 45 instead of 50 and when I turn the adjustment screw, the needle on the dwell meter doesn't seem to change at all. I'm also having a cold start problem and I think the mixture is causing it. What's happening is it starts for a half a second and dies, then takes several cranks to start and I get a puff of blue smoke from the exhaust which eventually clears up when the car is running. I've never had this problem before and this started when I reinstalled my intake. I don't mean to hijack this thread but any advice would be great!

No, because cold the O2 sensor isn't working. so the dwell meter will not change.


Puff of blue smoke on starting = valve seals are leaky. How do the spark plugs look?

Just did a full tuneup with new spark plugs, wires, cap and rotor. I also forgot to mention that the blue/yellow starter wire is unplugged because the electrical connector broke off, but I'm assuming this wouldn't be causing this?

That wire is just to boost your spark when starting the engine.

[DMC Fanatic]

If I reconnect it, do you think it'll help turn the engine over faster and possibly solve my issue? Or is it not worth it?

It won't crank faster but may start quicker because of higher spark power. If you have the Eagle starter, just connect it to the white/red wire.

Yea I figured it's worth a shot to reconnect the wire and see if it makes a difference. Thanks for your advice
