2 clutches in about 1 hour of cutting. Any guesses what would cause this? 1 of the 3 springs rattles out and the clutch engages at any rpm a bit d the chain spins. It happened to the old and original to me clutch yesterday. Last night I changed it out to a new china clutch. Used the saw for less than a half hour this morning and same thing occured. 1 spring dropped and away the chain goes even at a idle. Do you suppose it's a bent crank or would they have nothing to do with each other. I have had the saw for years andbthisvis a new problem for sure. Thanks
