I'm going to attempt a tune-up on my car and have many questions. I know most of these are basic questions, so please bear with me. Your help will be greatly appreciated!
My engine... 1974 1.8 Has dual Weber carbs. Not positive which ones. Distributor appears to be original? I'm assuming that the cam is original, really have no idea. I attached a couple pics that may help identify what I have. Sorry, it's raining outside and the car is covered, can't get better pics at the moment. Many questions, so I'll just ask them as they pop into my head, no specific order... 1. .016 gap correct for points? 2. At what rpm should I set timing? 3000, 3200, 3500? 3. What's a safe timing setting? 27, 28, 30, more? 4. Is it true if my point gap is set right, the dwell should be fine? 5. How do I sync my carbs? I have a synchrometer from previous owner. 6. Is my distributor supposed to have a vacuum line? Hmmm, I know there were some other ?'s but can't think of them right now. The car runs ok now, but I know I can get her to run a little smoother. When cold, it backfires through the carbs especially upon acceleration. Even when at running temp, it can be hesitant during acceleration at times. Once the rpms get up there some the hesitation goes away. These symptoms could be a common thing with the set-up I have for all I know, but I still need to give her a tune-up regardless.

I think I have the same distributor as this gentleman. I also have a weber progressive, and the idle is all shitty like his too. who is this jake individual and how can i get goodies from him?
I have the same problems as the O.P. hesitation, lack of high rpm power, flat footedness...etc. anyone have a guide for tuning the weber dgev (progressive 32/36) until i can get some decent carbs on there? |
