And that takes us back to post #61, where I said if you are within 4 or 5 degrees cam timing won't cause this kind of problem. I guess I should have said 4 or 5.5 degrees.....
In any case once your cam is in, and you know where split overlap is, subsequent checks could use the split- overlap method.
I guess we'll see...........

My Mentor taught me that method waaayy back,, he explained that jumping a single tooth on the cam gear was (IIRC) 6*, and the crank'd be 12*(?), so allowing for a worn chain,, as said ,, more than 6* needs attention regardless of whether it's causing a "noticed" problem.. It's a quick easy check to eliminate the T/C as a prob..

cheers..
