Bad spark?

yes i will try that soon, one time a week ago i tried a china distributor and the shaft dont goes in so easy as the real msd ones or oem ones then i grind that one to take it in, i didnt have a spark then and i want to put that distributor out, BUT THEN THE intermediate shaft COMES OUT TOO and i just put it in, that why i was asking if that part could be my problem too and if how and why?

Thanks alot for ur time!!!
