Timing.....

hmmm, i have the chain tensioner on my engine, there should not be much slack there.

Only thing i can imagine is that the intermediate shaft will climb up the cam gear and cause this.....i have another distributor and will check with this one.

@Tony: that would be great....but i doubt that´s the cause :-D. As far as i understand the advance system, it should not retard at all. Am i doing sth. wrong?
