My snow blower has a 4 inch pipe to drain the oil. In trying to remove
the cap at the end of that pipe, I discovered the cap wouldn't budge but the
pipe came out of the engine. I eventually resolved that (man was that cap
torqued tight) and put a 90 elbow with a radiator valve instead of the cap
so I could easily change oil in the future. Unfortunately this valve had a
slow leak and was very messy to use. So I'm looking for a bona-fide oil
quick drain.

Something like this: (Kohler part # 125237)

Unfortunately, that is for a 3/8" diameter pipe and mine is 1/2"NPT. (An
adaptor would be too much weight). Is anyone aware of one? A Briggs and
Stratton part number would be ideal. I've heard of B&S part # 5401D but
can't find any information about this, like what its size is.

Thanks!

Note to self, use yellow teflon tape!

Stick with the cap. Just put a washer in it (I suppose teflon would be
good). I went to Mobil 1 (5W30) on my air cooled engines including the
blower. Very pleased with the results. Well worth the extra cost on
those engines.
