Thanks Steve and R, cutout filed and oil thrower in place. Flywheel not fitted yet. Steve, I was going to come to the VCC meeting last night but getting the seal sorted and aligning the jets took far longer than expected.
I used diesel to test with. Since I have modified the oil ways by blocking the rear passage and arranging for oil to go into the front of the crankcase (via a filter) I was able to attach a hose to the barb at the front with a funnel on it. I could fill the funnel while holding it below the jet level then lift it up to allow diesel to flow through the jets. Lowering the funnel would stop the flow to allow adjustments with a short length of bar with a hole drilled in the end fitted over the jets.
Absolutely necessary to do this as they definitely don't squirt where they seem to point! I also found that on the Phoenix crank the holes aren't symmetrical as you say R. I arranged the jets as you suggest so it evenly hit both sides of the crank. The jets hit the troughs but not the holes fully. I remembered too late that Ian had mentioned to me ages ago about grinding the holes to enlarge the entry but now everything is assembled I don't want to risk grinding dust inside the engine.
As a final test I installed the oil pump and ran that. I used a new key which needed a lot of filing down to fit. I then ran the pump via the nut with a socket on a cordless drill. I tried without the camshaft installed as I wanted to check that the cam bushes were getting lubricated. No worries there. It's impressive how much liquid gets pumped about. Diesel everywhere!
I was thinking when I installed the sleeve that I would need the flywheel boss machined but using the one R recommended in an old post (can't remember the number off the top of my head) I found the boss was the exact right size to fit once I had wire brushed the paint away. The sleeve was too long so I carefully trimmed it down and made sure the edge was smooth so the seal isn't damaged when the flywheel is fitted.
