When starting my 147 from cold, I get a wee bit of a sqeek/screech, lasting no more than a second. It doesn't happen when the engine is warned up. Dealer says its the starter motor and needs replacing...trouble is, he's about as reliable as a chocolate teapot and keeps talking about warranty or the lack of it !!!!. Anyone come across this before and if so is there a quick fix or some sort of accurately directed lubricant to make the screech go away ?
