No, "SOLFOUND" is just the name of your eventhandler.
I think you need to catch and drop the solfound event by call something like
SCIP_CALL( SCIPcatchEvent(scip, SCIP_EVENTTYPE_SOLFOUND, eventhdlr,
eventdata, NULL) );
in scip_initsol and
SCIP_CALL( SCIPdropEvent(scip, SCIP_EVENTTYPE_SOLFOUND, eventhdlr,
eventdata, -1) );
in scip_exitsol.
