Own a 50hp merc 1993 always has run well –but last season it began running tough at startup–clears itself out in a couple min and runs great–But now it just won’t clear itself out–runs like 1/3 throttle and bogs down—couple weeks ago it ran terrible most the day the next day ran pretty well then started bogging down bad again–I/ve changed plugs and filter–no help—Ive always mixed oil and gas at 50-1 and Ive owned this for 10yrs without a single issue. One guy told me to mix my oil-32-1 -HELP any ideas???
