Hello out there......my car just got back on the road due to a bad coil and it was tricky to find as it still sparked the plugs....just not under compression. During wrenching we altered the timing and it is at 33 degrees btdc now. Car starts great and has tons of low end.....kind of stops pulling at 5,000 rpm with slight knocking. Replaced seemingly healthy vacuum lines to distributor and high end improved a bit and some knocking sound lessened. What are your experiences with not being at 27 degrees and what are the risks? Thank you very much. BTW.....not driving car for months is depressing and now driving is really a blast!! No wonder we are here.

Run higher-octane fuel to try to control the spark knock.
Knocking will kill your motor, given time. Air-cooled engines seem to be even more vulnerable than water-cooled, likely due to less-perfect cooling on the heads. --DD |
