Timing

As I can do nothing but think about getting back to my boat in the spring I have a new question.<br /><br />In theory, how far out can the timing get when you change both a pp and a tb.<br /><br />I checked the timing last summer, but as winter crawls along, I'm second guessing my findings.<br /><br />Perhaps I sheared a flywheel key and am not getting an accurate reading. No, I did not verify the pointer like I was supposed to. I realize that was a stupid omission in the procedure.<br /><br />I did make a nice piston stop tool this weekend out of a 3/8 bolt and an old spark plug. The first decent day we get in March I'm going to Maine to start over. <br /><br />Just curious about how many degrees it could have changed by replacing ign parts. 2, 5, 20? What's the most you've seen?<br /><br />Just me posting this displays my boredom level <br /><br /><br />J120TLES

Re: Timing

If you changed the timer base, It would be a good idea to verify the timing, as the timing link is mated to that. With your new stop tool, use a drafting compass, along with the measuring scale, or ruler. The compass make's it easier to find the mid-point. Did you get the diagram for your volt meter in the mail?

Re: Timing

Yes, I got the diagram today and thank you. I'm going to put one together and see what happens. I checked on the net for parts and it looks like less than $5 to make it.
