Mastercraft 820250 leak?

First, are the first and second pair of pix the same machine?

Regardless of that, the second set looks like the intake - air coming from there suggests a bad intake valve.

You'll need to get that shroud off and then you may be able to turn it manually to confirm.

Alltrade has a parts list for it, but you'll probably have to make any parts (reed valve(s), gaskets) you need.

Good luck.
