Yeah, cheers Scott.
The motor off the spare saddle was mostly dust inside, still a few servicable bits inside. The one off the complete mid was good but stripped it to check anyway only to find that the 'hex' drive in to the pump was almost round, so swapped it for the other. Still got enough spares for another complete motor too.
Checked all compressions today, all 115 cold. Aint so bad for an old smoker!!
Shame your not out though, be good to have a charge about.
Thanks again mate.
