Hi Guys

Came to the conclusion today after much testing that my starter needs replacing. I had a off aircraft battery attached (as the aircraft battery was suspect) showing 14 v constant. The solenoid was clicking and showing 14v getting through to the starter cable. The starter would either do nothing/ spin without moving the gear forward / engage starter gear and jog engine but not spin it. So we came to the conclusion that the starter is suspect. The electric starter has worked previously, albeit sometimes slowly. Last time the engine just wouldn't start and drained the battery.

So, how do I get the old starter out? The firewall has a box coming into the cockpit that is rivited together, so no access there. Do I really need to move the engine completely? or is there a trick?

I had a forum search but I couldn't find anything.
I've got a new rotax starter to go in but I was after advice before I go for it.

Thansk in advance
