Craftsman self propelled 6.25 HP starting problem
My lawn mower does not start quickly unless I squirt some oil into the spark plug hole. Then it starts with the next pull. It is not much of a problem to squirt the oil in, but I was wondering if there was something that could be done to eliminate that problem.

ck for loose head bolts. i had an old tecumseh that would not start until i tightened some loose head bolts. putting oil into cylinder increases compression.

on the head 
I think there are 8 without lookin, they surround the spark plug. The spark plug screws into the head, which is bolted to the cylinder. There is a gasket between that needs to seal in order for the piston and valves to build compresion. Oil will fill small leaks momentarily to allow compresion to build.
This could also be a sign of worn piston rings or cylinder lining.

use 1/2 in. ratchet. stagger your tightening sequence. tighten to snug. on mine 3or4 were loose. about 1/2 turn on each and go back through sequence. use one hand so you dont overtighten.
