Pull those blades closer together and you'll have juice on the semi again.
So you have to take apart the mechbox and trigger assembly.

I've seen similar problems in two Echo1 P90 gearboxes. On one they were too far apart causing only full auto to work (and no reaction while in semi). On the other gearbox, the two metal tabs were actually too close, causing the trigger switch to have contact for too long while returning (thus full autoing even if only tapping the trigger slightly).
On yet another (Marui) P90 gearbox, a friend is having trouble with only getting full auto. The strange thing is that it only appears when he uses 11.1v lipo batteries, AND it does by the way have an AB mosfet installed. With a 7.4v lipo and conventional batteries he doesn't have this problem, making us wonder if the 11.1v lipos actually cause the gate-signal to be powerful enough to jump across the full auto contact plate. Absolutely mysterious indeed, but he's getting a normal 7.4v lipo now anyways
