METHOD
CONSTANT SPEED TYPES
Climb on Schedule, Rad Full Open +6.25Lbs Boost/2800RPM Mixture AUTO RICH (Back) In Spit IIA I used +9Lbs Boost/2800RPM. Temps and pressures all within limits throughout climb. Climb from 6500Ft to 12,000Ft
2 PITCH AIRCRAFT
Climbed +6.25 Lbs Boost/Coarse (about 2400RPM) Rad Full open, Mixture AUTO RICH (back) on schedule. Then Repeated the test at 6.25Lbs Boost/Full Fine (about 3000RPM). Again Climb from 6500ft to 12,000ft. All Temps and Pressures within limits.
Only aircraft with an issue was Spit MKI A 100 oct its symptoms are:
Climbing at +6/2800RPM passing 9500ft I get a couple of audible "put" "put" from the engine, passing 10,500ft I get very rough engine running. Reducing Boost to +5 and it smooths out. It also smooths out if I maintain +6Lbs boost but reduce RPM to 2600. Either way this shouldn't be happening.

I get this also in the Spit 1A 87 Octane.
