to be clear when the timing belt jumps, for me it always seemed to retard timing
i ended up advancing it to get it to run
remember the timing chain runs the CAM shaft, so and driven by the crank
so when the chain jumps it throws out the valve timing, not just spark
you move the Distributor to get it to run, so its not firing thru a valve
but the piston and valves are NOT in time
compression is not correct when the spark fires
Does a chain skip also tend to retard timing?
And yeah. I'm aware of the relationships between shaft, cam, chain, valves and distributor.
A belt skip of 1 tooth would seem to likely cause less timing issues than a chain tooth skip... so I would think.
