    rough running....backfiring 350

    if the vacuum line to the distributor wasnt in place when/if the timing was set wouldnt it be incorrect? I am trying to grasp the sequencing of what happened.

    rough running....backfiring 350

    I certainly appreciate all the help. Just to get closer to where things are supposed to be. I have not changed timing I just tried to land tubing where it is supposed to go.

    Thank you Sir. So that leaves the EGR port open, ok to cap that or where SHOULD it go?

    rough running....backfiring 350

    Here is another question..... The vacuum line from the distributor....it is hooked up to what shows in the 2nd pic to the EGR port (labeled C) and not to distributor vacuum port ( labeled F). Am i safe to assume this is incorrect as well???

    carb connections...vacuum booster connection

    thanks for the replies and pics....i think I am in need of a 1/4 inch npt x 3/8 barb fitting...might try a 90 degree bend if it has enough clearance to rotate around....

    carb connections...vacuum booster connection

    The port on the back of the carb is plugged. Didn't have a booster b4.. I just need to find the fitting to adapt from threaded port to tubing.....what size and thread is that port if anyone knows.

    carb connections...vacuum booster connection

    I have 2 pics one shows the current connection for my new brake booster/master- I didnt install. The other pic is a quadrajet info sheet I found online. I need someone who knows more than me to explain this to me. The way i see it the vacuum booster is connected to port G - bowl vent.....this...

    rough running....backfiring 350

    Thanks. I drove around the neighborhood and it was much improved. But still has a ways to go to get where it should be.

    rough running....backfiring 350

    The information I have been. Given on here has been huge .

    rough running....backfiring 350

    So 1st thing I did was confirm the wires/firing order is correct. I believe it is correct. I just replaced the vacuum hose from the distributor to the carb. Big improvement. Still got a cough/backfire occasionally. Possible fouled plugs since the vacuum advance wasnt "breathing"? I am trying to...

    rough running....backfiring 350

    So I have not touched any plug wires except to label them ( see pics) . I think since Lego pointed out my labeling error I think everything matches now....

    rough running....backfiring 350

    I want to learn this stuff. I saw that vacuum line off the distributer and it seemed wrong to me but I am inexperienced heading to get some 5/32 vacuum tubing and we will see.....

    rough running....backfiring 350

    this engine will run fine in park and when you rev it up but when you start driving is when I have the backfire/misfire crappy stuff happening.
  24. Ken B

    rough running....backfiring 350

    I am thinking the same thing. but you guys on here know more than i do. I was told to check firing order...so I am just trying to confirm that its all correct. I will label stuff more permanently later. Just trying to figure out the misfire and learn WHY....

    rough running....backfiring 350

    Rikko, If you can see that vacumn line I USED to have....thats where is should land on the carb from the distributor correct? vacuum hose has blue painters tape on it
