    I just took a look at my A25 and A35 side by side.With out actually trying it,I would say the heads would inter-change.Have you checked to make sure your rope plate serial# matches one on crankcase?The differences between the two power heads are pretty subtle.Looking at your pics I’d say yours is definitely A25 and lower unit is from A35
