01 60hp timer base

I have a Johnson that needed a new timer base and I replaced it, ran well for about 15 hours and now I have a miss on # 2 cly. I replaced the plugs and no luck so then I took off one wire at a time and it seems as if #2 cly is the one. It is still getting spark but it seems as if it is not at the right time. Another timer base gone bad? Carb OK. I do not have a stevens meter but tried with an amp probe dvm with peak hold and when cranking with leads on white And (blue ,purple,then green) I get .5 - nothing and 5vdc. Also With the motor off I checked continuity between white/green, white/blue and white/purple and there is none, book says there should be something. Do I need the stevens meter even for this ohms check also?

no, ohms check can be done with any ohms meter. if you think your timing is wrong you need to put a timing light on it to be sure.
