Cheers guys - a new throttle lock thing is on its way
I'll probably start the engine ' properly ' on sat on the muffs.
The battery is fully charged and I'm hoping will stay that way when running .
Managed to find the steering issue - not at the engine or the cable movement , but the cable is not seating correctly within the helm- so its being pushed 'up' and out of the run on the gear and rubbing against the helm housing . Fully stripped and greased and it now seems fine.
Oil leak seems to have stopped ( I think it was simply a long tow home bouncing about when tilted ) .
One other thing - the black rubber seal on the cowling is loose and I cant seem to stretch it to get it back on the cowl. Anyone know how to give it some stretch to get it back on - I'm think heat it up a bit ?
