FV432 help

[rob love]

I am working on a FV432 that I and a partner purchased last winter. It came with 3 power packs. These are the gasoline version, and I believe they are B81 engines. I think I spotted 1980 casting marks on the blocks, and one was last overhauled in 1990.
1: The pack which was pulled from the vehicle for a bad starter. It was reported by the previous owner as running poorly: he suspected burnt valves in a couple cylinders.
2: A pack salvaged from a carrier in the late 90s which was heading out as a range target. This engine is siezed solid from poor storage.
3: Another pack which was salvaged from a range target. It was, like pack 2, brutally ripped out, with hoses and wire harnesses cut, lifted out with a chain, and suffered some damge as a result. Oil reservoir had rusted through.

I have spent a bit of time this summer assembling pack no3 for use. Anywhere there was an opening, the mice got in so some time was spent removing tubes and cleaning out the debris. The air filters also had mice present in them. half of the spark plugs were so rusty, they broke leaving the prorcelin and the base in the spark plug hole.
I am finally at the point of trying out the pack before installation. I was able to prime the lubrication system by filling a small air tank with oil and pressurizing it wile it was hooked up to the oil galleries on the right side of the engine. I had it cranking with the solenoid and the coil hot wired but could not get it to fire. When I opened the coil housing up, a fair bit of oil came out, and the resistance of that coil is nowhere near the resistance I got from the coil out of pack 2. I'll move that accross tomorrow and hopefully get it to run up.

Of course, the pack is super engineered. I would expect nothing less from the British and Rolls Royce. However, I was a little surprised (and miffed) at the low quality hose clamps. They are more akin to the chinese clamps one would purchase from the dollar store. In our military, we use stainless steel clamps (usually tridon brand) which will last forever.

I noticed I can turn the engine in the direction it is supposed to rotate, but cant go backwards....the engine locks up. I tried the same thing on pack no1. and it will rotate forwards or backwards. Can anyone explain why it will not rotate backwards?

Update: problem went away......not sure what changed. Got the pack running on the ground today. Have a leaking carb so I'll try one of the other carbs. I'm hoping to get this pack installed before the snow flies, which could be anytime now.
