The advantages ??
1. You won't have to go anywhere to get the ones you need.
2 If you bought new ones--you may find there not just right and have to go back for more--and you can't adjust the clearances exactly the way you want---you can just get close.
3. No cost to you.
4. You can get the clearances exactly what you want---------I always go to the maximum clearance recommendation so as to prolong further valve clearance checkings or adjustments.

I simply measure the clearance---figured out how much thinner a shim I needed----took the old one out---measure it with a caliper and sanded it down to the thickness needed--checking with the caliper---put the shims back in------everything was perfect------perfect is adequate !!!!

The cams don't rub the shims---you are not degrading the metal of the shim.

Take your time---it's an all day job.

If you get frustrated----quit--take a break--come back the next day if necessary.

Drop a part down the motor ??? slit your throat with one of those Rambo knives.
Mark,

Thanks. I plan on reusing shims to correct other valves. A musical chairs of shims if you will. It would be great if I could have them all out at the same time, mic 'em, and swap around until I got it all right. What are the chances I can reuse every single one??? Slim as a shim methinks.

I plan on reusing as many as possible and swap out those I can't find a home for. My point in the original post was to find out if I need to put the front head back together before tackling the rear i.e open up 4 new possible canidates for musical shims.

EDIT: Just reread your post. Likely that all shims will be thinner? Can I get a comeback on that? That would be good news. I have float glass and honing compunds for my Japanese chisels if I get really anal.



Oh, and I prefer a 12" Nailcutter blade in the Sawzall. That jagged wound seems to get the job done faster. Plus chicks dig scars.
