Newer seen the drawings so I'm only guessing here .... is there a vane pump on the inside ?
Nope.

But i think i got the answer. Look at the drawing, there is 2 intakes tube that are higher on the manifold ( to prevent hydrolock of bottom cylinders ) , i guess the offset in the cover is for centering the carbs vs the intakes tubes.

I think you might be right there. I always wondered about that. Without the elevated tube ends in the manifold, any fuel flooding from the carb would drain directly down the lower induction tubes & sit in the head ports until valve opened & then bad things happen. Makes sense.

On my radial, different induction path as mentioned previously. But that makes my liquid accumulation sump the master rod groove in the crankcase. At least only fuel vapor can go to heads, but I am making provisions for a drain plug in the bottom of crankcase.

Anyway good observation.

I have started following along. Amazing how much you miss when you travel. I have seen other builds on the Edwards radial 5 but I think they were on different forums. I have 2 radials on my bucket list the Kinner K5 in SIC and Jemma also in SIC, someday.

Did the pistons today. I changed the ring groove to 1mm( 0.039") instead of 0.0325" because i already had the 1mm grooving tool, so i adjusted the pattern.

I will make the ring 0.008" thicker.

We got a little problem with the 1250 post-processor, so i decided to change the rocker shape to make it easier to program directly on the cnc.

I'm little bit lighter, same strengh.

Will try to cnc it this afternoon.
