Find out if a high compression piston was used. If so, run away.............fast. A very well document problem occurs when a high comp piston is used in these motors. The increased compression will cause the cylinder head studs to start tearing themselves out of the cylinder, and the first sign of this will be a head gasket leak, which may sound like a valve tick, or the sound heard when a spark arcs. There is a fix, which requires removing the cylinder, then drilling and retapping the holes to accept larger studs. It can be a little pricey if you don't have the mechanical know how, so I would suggest looking for another quad.
