I am going through my valve clearances. I was able to get the clearances for all valves. I was also able to take out the shims on the intake side, once I had a magnetic pick-up tool. However, I can't seem to get the shims out of the exhaust side. I've tried the two on the left and both will come out of the bucket, but not out from under the cam. Anyone have any tricks to try for this? I'm using the zip-tie method, by the way. Thanks.
