Fitted the propellers, Checked all fittings and performed the oil purge.

First start went ok, however, the intake valve on the #2 cylinder would not check. The problem is not the clearance with the valve and the rocker but that the lifter has no compression at all. The instruction say that if you have a "soft" lifter to run at 3500 rpm for 5 minutes to purge the remaining air out but I am hesitant to do so with such a loose lifter.

I have a question in to a Rotax mechanic to see how I should proceed.
