Hello All:<br /><br />I tore apart a carburetor for a 56 Johnson 5.5-hp outboard yesterday and I was fine until putting it all back together (isn't that what always happens?) Anyway, I screwed up and didn't remember to write down if the "skinnier" spring (diameter about the width of one of the needles) or the "fatter" spring (much thicker than the width of either the high or slow speed needles) went with the slow speed needle. I have been using Clymer's Old Outboard Manual, Volume 1 as a reference, but these last two springs are not on the carburetor diagram. Is there anyone out there who may know where these springs go?<br /><br />Secondly, once I get these springs back on, what are the nuances of putting the high speed and slow speed knobs back on so that they are properly set and working (idling and running right)? Since this is an outboard produced prior to 1960, the high speed and slow speed needles are directly connected to the high and slow speed knobs.<br /><br />Lastly, some items were inadvertently lost during the cleanup process. When soaking the carb, I forgot to remove the gaskets on the float chamber and the carb body where the high and slow speed needles insert. The carburetor is separated from each needle by two gaskets put together. In each case, one of the gaskets almost disintegrated and the other one was badly damaged, as a result of soaking in the carb cleaner. Can these gaskets be replaced (buying a carb kit, etc...)? Also lost a small cotter-type pin off of the cam follower. I have the other one to use as a reference, but just need to replace the one I misplaced. Can this pin be replaced?<br /><br />I know it seems like alot, but its my first attempt at outboard repair, and instead it may have turned into outboard demolition. :confused: I definately learned some things - like make sure to diagram what you are taking apart if there is a question, etc... In any event, ANY help would be greatfully appreciated. <br /><br />This forum rocks!<br /><br />Thanks in advance for the advice.

Hello.<br />The widest diameter spring goes on the low speed needle valve(upper),The smaller diameter on the high speed.<br />Keep the knobs off the needles at first.Turn the slow needle closed hand tight then 1.5 turns out.<br />The fast speed 3/4 of a turn out.Now put both knobs on in middle position.Go to the lake and fine tune the carb.After all that is done.loosen the knobs again and tighten them in middle position. <br />The gaskets and pins you lost are available on e-bay and many stores like:<br />www.twincityoutboard.com<br />your local napa store or dealer,as parts of carburator tune up kits.Do not let them tell you they don't exist anymore because they are widely available.<br />If you are still having trouble,go to your library and look for the Johnson /Evinrude Outboard volume one.1956 -1970.,This is a Seloc book written by Joan and Clarence Coles.<br />On page 4-17 you will find a very clear blown up picture of your carburator that shows you exactly what to put where. <br />Good luck.

Thanks for the advice.<br /><br />One more thing. I also did not mark down the sequence for attaching the cover plate and air silencer back on to the carburetor. Yes, I know, I'm learning... The items involved are cover plate, rubber washer, spring, small diameter rubber gasket (fits right over the slow speed needle), plate for back of motor, and slow speed knob with screw. Can someone tell me what order these need to be in to correctly attach the air silencer and cover plate to the carburetor. <br /><br />That carburetor sure looks clean, though...

Oh yeah:<br /><br />I forgot to add the nut for the slow speed needle to the list of items I need to get in order. <br /><br />Thanks again.
