We managed to unjam the engine 🙂
On removing the starter motor we discovered a huge chunk had broken off.
Luckily I was able to stick my hand in and fish it out from the engine starter gear.
Engine turns again now.


Unfortunately we were less successful freeing the rear wheels. The pad adjuster bolts will not move at all.
We will try removing the wheels next time. Would heating the drums with a heat gun be a way to free them maybe?
thanks,
Mark
