Web5 de fev. de 2014 · Way too much spark timing. Try this test; do a WOT 1-2-3-4 to redline. That really increases the combustion chamber temp, and I will bet there will be audible spark knock. You don't need a dyno, just do a WOT scan in 4th gear from 1000 rpm to redline, note the elapsed time in the scanner. WebGeneral engine features. The B-series features engine bores machined directly into the block (rather than the wet liners used on earlier Cummins engines). It is also set apart by the use of a shallow one-piece head, requiring closer tolerances than in other Cummins products. Unlike other diesel engines of the time; the B-series Cummins used direct … Web16 de fev. de 2024 · In my high compression V8 I destroyed 2 starters due to violent kickbacks. After setting cranking advance to -2 degrees (after TDC) I haven't had any problems with kickbacks and destroyed starters. In my case I think the problem was the very uneven speed of the crankshaft when cranking a high compression engine. can non ferrous metals be magnetic
