But there's another very good reason to use _marine grade_ tinned wire. Marine grade wire uses much finer strands than automotive wire. It also uses a different insulation that is slightly thicker but much softer. The end result of both of these is that marine grade wire is much more flexible. This becomes important when routing large bundles of wire in a tight space, or when routing heavy battery and starter cables.@(^.^)@ Ed

Tappet replacement?
I have noticed some wear on top and bottom of a couple tappets- in the first photo the top of the closer tappet is scored in a circular pattern. In the second the bottom of one tappet has some weird wear almost like an inclusion in the metal.
Should I:
A. Dont be concerned
B. Machine the surfaces that are questionable
C. replace any questionable tappets
D. Replace all the tappets
I don't want to overthink all of this but I want to do it right.Pearson 30

Those are not too bad yet. probably won't make a hoot of difference in running. It looks like the vlave lash may have been a little loose. The circular pattern is from the tappet rotating in it's bore. This is normal.
A machine shop with the right attachment to their valve grinding machine can recondition these for you. Don't try it yourself; It has to be absolutivly spot-on done rightsigpic Whiskeyjack a '68 Columbia 36 rebuilt A-4 with 2:1

Niel ,
THANK YOU !!! Now I can come out of the closet - I am a TINLESS Afourian !
I used the same logic - the original wire was not tinned and was relatively intact after 45 years , just rat-nested and FUBARed beyond hope , so I tore it out. I'm 59 , so I think my new wire will outlast me.

To qualify my blasphemy somewhat, if I were planning on blue water cruising I'd have nothing but tinned wire onboard, no question whatsoever.Neil

Crank hard to turn
I am re-assembling the engine at this point and after I have installed 2 pistons I can no longer turn the crank by hand. It turns very freely without the rods attached. I noticed that the manual says the crank should be hand-turnable after the rods are attached.
My cylinders are bored and honed .020 over, I have new pistons .020 over, and new rings .020 over. Is this OK or should I stop at this point?
ThanksPearson 30

Is it necessary to do the pistons .020 over if you are using the rings? I always thought you can use the same pistons, just do the rings .020 over?
Pull the pistons, check the rings fitting inside the sleeve for clearance. There is supposed to be a tiny gap where the rings touch together. You do this without the piston to check for fit. If too tight the shop did something wrong.

Check to make sure you have not installed the rod caps backwards. The number stamped on the side on the bottom end of the rod and the number stamped on the side of the cap must be on the same side - so that the number on the rod is right above the number on the cap.
Also make sure you've got the pistons in facing the right direction - the arrows on top of the piston that say "front" point towards the reversing gear, although number 1 cylinder is the one closest to the flywheel.
And yes, STOP until you get this figured out. I just replaced all of my bearings and rings, with stock standard size, all four are in and the head is on and I can turn the whole thing by hand without an inordinate effort. However, when I was first reassembling, I put the first two in and then couldn't turn the crank, and that is when I discovered I had put the caps on backwards.- Bill T.
