Timed 13 degrees with CO set, Vac lines are correct, and I'm still having trouble. I just took out the intake to clean everything and rebuilt the mixture control unit to make sure there were no air leaks, there were some air leaks around #102772 which is now all fixed. I'm now confident that there are no air leaks at all. Anyway, when I start up the car it will misfire at anything over 2000-2500 RPM until engine is warm. Warm or not now- when accelerating from idle I get a quick burst of black or blueish smoke [depending on CO adjustment], and the engine will take a second to respond, as if the sudden increase in air is too much for it to handle. Also sounds like misfiring at high RPM range, over 5000; obviously this happens when the engine is warm, I could never get it to rev this high cold with these problems. I never had these problems when the engine was out of time, and even for the first few days when it was changed back to 13 and distributor fixed, now the running quality is deteriorating! CPR bad? fuel distributor? I will be replacing the CPR within the next few days, because it's likely to be original and I've replaced most everything else anyway, so why not I figure. Other then that, I'm out of ideas...As always, any help is greatly appreciated. -----Dani B. #5003 To address comments privately to the moderating team, please address: moderators@xxxxxxxxxxx For more info on the list, tech articles, cars for sale see www.dmcnews.com To search the archives or view files, log in at http://groups.yahoo.com/group/dmcnews Yahoo!
