unsiezed motor, starter works, now need info and ideas

[a_bullfrog_a]

Hi All,<br /> I a couple of old chrysler 120 hp outboards on <br />ebay for cheap. They originally came from one of the many summer camps near here in the catskills(camp name is writen on side of one).<br /> I did a little p.b. blasting and got one to spin<br />free from the flywheel to the prop. I hooked a car battery and jumped the starter and that works.<br /><br /> Now I'm determined to get the motor to turn over.<br />I need to know how to check to see if the alternator <br />is sending spark through the spark plugs and i've never had a car with a carborator so i'm a bit lost looking at the one on the outboard. how do i test them and check for proper fuel flow and spray. help me bring life to this old beast.

Run a compression test first. look for equal compression in each cylinder (within 5lbs of each other), and over 90PSI.<br />If you don't have passable compression , i would part them out on ebay.<br /><br />If the comprsssion passes, spray a couple shots of premixed gas directly into ther carbs, and try to start. It should sputter, or run briefly.<br /><br />If it does, the ignition is fine.<br />If it fails to cough even, we need to look into the ignition.<br />No doubt tho, that if these motors were seized-up, you can count on rebuilding the carbs and fuel pumps. It's only a bear the first time, so don't shy-away from the carbs.

Look in the FAQ section. The posting on reviving an old motor is very detailed.<br /><br />Mike M.
