Might be able to pick up a used muffler from of a small gas engine repair guy modify an existing muffler instead of fabricating a whole. Ear plugs are sold much cheaper.the mufflers are probably available? it is an old ass saw though.
You got your name right if you like manual oilers lol. Haven't used one in 30+ years and my thumb is still mad at me. (my 084 has an oil booster but you just hold it down when exter oil (pronounced oral...) is needed)
