The valve are making noise and need to be checked.
1st. change oil and filter.. use 10-40.. if that doesn't quiet them... .0025"-.003" on intake .004" - .005" exhaust should do it... if they are too tight,,it won't idle down fast or well.... or excessively tooo tight -won't start..too loose they rattle or if there is a lot of wear.. the rocker arms may need replacing
