Thanks once again for the replies everyone.
Like I mentioned I wasnt sure if I could describe it correctly. The
sound isnt high pitched like that of a belt slipping squealing (like say
a car belt squeal) but just the engine sounding like its revs up/down so
Ill change the sound to rrrrRRRrrrRRR.

It also takes more thean the 1-2 pulls like 5-6. Im going to take it in
see what happens
