Hey Frank, I have a metal bracket, actually used to keep a Carrera tensioner compressed that I used to fit in underneath the "foot" on the idler arm and the bottom of the chain housing that did a perfect job of keeping tension on the chain. If you want it, it is yours for the asking. Along with the dial indicator you are either going to have to get the z-block to mount it or rig up some other type of mount.

For cam timing? You can just use the tensioner tool:

Ok great I have the Z block,..I could get a Dial Ind at Harbor Frt,..But there not trhe Metric version...Thanks E-M flmont@mindspring.com

Be careful before you buy the HF dial indicator. It is very inexpensive, but the stem may be the wrong size to fit in your Z-block, or any other standard holding fixture. There used to be a good inexpensive Russian-build metric dial indicator on the market, but I haven't seen it sold by anyone lately.

I'll probably get flamed for this, but I just (as in 10 minutes ago) made a simple chain tensioner from $1.50 worth of hardware store bolts. I used a 1/2" dia x 2-1/2" long bumper bolt, a 1/2" x 1-3/4" threaded coupler, and a 1/2" socket head set screw. Thread the set screw into the coupler from the bottom, so the tip of the set screw is just flush with the end of the coupler. (I used some Loctite to keep the set screw from turning) Then, thread the bumper bolt into the coupler. The set screw end of the assembly presses against the tensioner arm, and the base of the bumper bolt fits inside the chain housing. I used a couple of pieces of delrin at each end to keep from marring the tensioner arm and to distribute the load on the cam chain housing. When you turn the coupler, the assembly gets longer and tensions the chain.

Let me add that I in no way recommend that anyone try this setup and will take no responsibility if someone does try it and it destroys their motor.

Seems to work fine, though.
