Need some help please! New to outboards/motor repair. Picked up a beat up old '57 Evinrude 3HP to see if I could get it running for my canoe. But can't get it to start. Here's what I've done so far:
-- Read "Outboard won't start" in FAQ.
-- Ignition system tune up (new coils, points, plugs, condensors)
-- Carb clean and tune up kit
-- Flushed fuel system; new fuel mix (24:1)
-- Replaced impeller
-- Lastly, new head gasket (and tapped out old sheared head screw) hoping this would do it since it felt like compression was low (have not done a real compression test though)
(All above work done according to excellent instructions at http://outboard-boat-motor-repair.com.)
High and low needles set at various points, including multiple attempts starting at and around recommended HS 3/4 and LS 1.25 turn. Getting very good spark. Also tried starting fluid.
I can get an occasional slight spit-sneeze out of it on some of the first few pulls, but nothing more.
My gut tells me its a carb problem -- flooding -- though I have little engine repair experience. As I said, I did a complete carb tune up kit. Did not replace float, but it seems in decent shape. I've taken carb apart and put it back togther 3-4 times checking my work. Float is set even. (only thing I was really unsure about was float needle spring placement, which I simply hooked around the side of the float arm.) The bowl of the carb does have a 1/4'' hair-line crack on it's side, which leaks. Some gasket seal has leak temporaily fixed (thought I'd try JB Weld for more permanent fix--is there something better?) When I try to start it -- with choke out and recommended set for needles (and with exhaust removed so I can see what's going on) -- after a few pulls I can see that gas is pooling/present, and, when I push the choke in, an amount of gas (? 1/8 teaspoon?) spills out. Is this flooding and if so, what have I done wrong, what do I check?
So, carb problem? Maybe I set the timing wrong (though I really took my time on this step)? Compression (and what would I try next)? Something I'm totally missing?
Thanks to anyone who can provide some guidance. Sorry for the long post.
