I always prime my Yak this way: After getting fuel pressure with the handle to
the left, I only prime (with the handle to the right) until resistance is felt
(primer is full of fuel). Then I hit the start button and give it one or two
shots while it is cranking. It always starts right away!

This way you have 3 cylinders way too rich to start, spark plugs literally drowned
in fuel, and the remaining 6 way too lean.

When using the scuba tank to re fill the main air tank, does the main air tank
valve needs to be in the open position or closed?
When do I know , I have put enough air in the main tank?

Is the scuba tank plumbed into the aircraft?=C2- If yes, it will depend
on how it was plumbed into the aircraft.=C2- Assuming it is plumbed into
the fill line from the external air fill port, yes you'll have to open the
main air valve.=C2- Trace out the line from the scuba tank to wherever it
plumbed and then draw it out on the pneumatic system schematic.
Assuming you're filling with the scuba tank and it is plumbed into the same
line coming from the external air fill port, the pop off valve should pop
off.Dennis
