Bosch 10.8V impact driver

Bought used many years ago. Always had a intermittent fault in that the lights would come on, but the motor wouldn't turn. Jiggling the fwd/rvs button usually got it working.
Finally took it apart and there was a loose wire into the main block - a push quick connect terminal. It played up at first use, but seem ok. Maybe the switch block needs stripping.

Servicing

Junior. 0.55 L 10w40. Had been chugging a bit, so new carb membrane, plug cleaned, new foam filter + primer bulb (routine change old one ok).

Strimmer. New fuel filter, Araldite fuel tank, new cap. Was ok, then started stalling low revs. Crap in carb + adjustment, but still doing it.
