    If you can run moore initial advance (like 14-16),  you can close the throttle plate a little more and reduce dieseling.  Lean fuel mixture also causes it, so try setting the idle mixture up more rich - with a little lope to the idle.  Also make 1000% sure there are no manifold leaks as the smallest vacuum leak can cause hot spots and run-on.  

    Thanks for responding

    Thats what exactly what I was told by redline weber tech.

    Thanks

    5w is for newer cars, It's much thinner and gives better mileage. It's not good for a Datsun above 0 F. I would never run it.

     

    Again what is making you think the oil is too thick? You're in California and a thousand miles farther south than me. The average low in Dec and Jan in Modesto is 40F.

     

    The coldest day on record for Oct 6th was in 1969. It was 42F.

     

    Right now it's 78F

    Ok I got the noise under control.

    What I did was I checked the timing. its around 12degs.

    Then I opened the fuel mixture screw 1/4 more turn out.

    I closed the speed screw say about 2/8 turnd in.engine started to run smooth.98 % of dieselling gone.I even check oil pressure,its around 22psi at idle,

    That funny noise coming from under the valve cover is gone..

    So my guess is ,my intial adjustments were too lean for the engine causing it to make noises,which had me confused so I started looking at oil,oil pump etc etc.not realizing that the real problem was my carb was way out of tune.

     

  3. What's up.ratssons.

    So I having a bit of trouble after I installed 38/38 weber on my l18.the engine is dieselling after I turn off the ignition.never had this problem with the old carb.

    I only jets I swapped ,is the   idle jets from 50 to 45s.mixture screws are 1.1/4 turn out and speed screww is at 1/2-turn in.ignition timing is at 10-12deg.my question is .is it over caburated for 1800cc ? Vacuum leaks??

    Any one had this type of problem before..??

    Thanks
