Electrical problem
1974 Volvo 240 Two Wheel Drive Manual

setting ignition timming with timming light when I set the timming I adjusted it to 10 degrees btdc I went over to about 12 degrees I moved the distributer back 2 degrees to 10 then it was set right at 10 at 800rpm but engine cut out. But if I set it to 12degrees then move back to 0 then move to 10 the engine is fine so why does it cut out if I just move it back 2 degrees? If you can answer this one then your a beter mecanic than I I have 20 years in the trade.
