Additional photos, I couldn’t find my feeler gauges however I could slip a piece of card into the gap. I’ve no doubt it has all been machined, it’s just that gap that gives me concern.

It’s a large enough gap that my attention was immediately drawn to it and the ring.
I’ll attach the original photo. If I had to guess (I will try and get some feeler gauges on it) I would say it’s at least 40 thou.

It's a pretty grainy picture but I wouldn't expect to see that much of the ring. How much clearance would you guess you have between the piston and cylinder?

I’ve bought a French refurb engine and decided to give it a check over to be sure it’s not deteriorated since the 60s.
Externally it has some minor surface rust and has a damaged distributor cap but I thought I should take the head off to check the bores are good and there’s no foreign objects that have appeared over the last 60 years.
It looked good, a bit dirty where I guess it has a post build test run, but the cylinder walls are shiny and no marks anywhere, but then I noticed I could see the top piston ring between the piston crown and the wall. I’ve never seen this before and feel it’s far too much to be clearance. The pistons are plus 30 and I’m wondering if it’s got the wrong size fitted, even though it’s obvious run. I’ll attach a photo so you can see for yourselves (red arrow pointing to gap in ring). Is this normal?

I had an early lot 5 with the same carb, I think they are interchangeable but the air horn is different. The updraft style air horn is a lot harder to find but neither one is easy.

Hi. My Scout car finally arrived yesterday. The First thing I noticed was the Carburetor, (Early Lot 5) is a straight Downdraft. The NOS Carburetor I got was a 90 degree bend, (Later model) Carb. has anybody interchanged them? I would have to waste it if I don't have to. Thanks.

Get the radio manual for your halftrack. It has all the routings listed. Just FYI. The radio terminal boxed were installed at the factory when the halftrack was built. Some had the larger square box and some had the smaller rectangle box.

so weve reached the stage on our install, that we need to figure out how to rout the armored flex, to the battery box.
I guess on our Izzy return they put a tool box or something under the passenger seat. and that block the way,
anybody know how an original was run ??
thanks
