    got this carb yesturday out of a small outboard engine. 8 horse or less id say. engine cover was missing so i have no idea what brand it is. no idea what the carb is either. does have an "m" cast into. there are also two other outboards i could take carbs off of, ones a 8horse yamaha, the other is an evenrude seahorse 2hp? think i might have somethign i could work with?

    in the top left corner of the first pic does it say OMC on the fuel hose? If it does then it's from an evinrude or johnson (both were manafactured by OMC). BTW OMC went bankrupt in 2000 so it would be from before then

    it would not hurt my feelings one bit if you didnt bother replying. i was not the one to remove this carb, nor did my father know what engine it was. the engine is at where he works, and the carb is at his house with my bike. so i cannot look at either at the moment.

    Seems right. What are you gonna use it for? Carbs are pretty universal, if it wasn't the exact carb for the motor it should still work fine (with adjustments)

    I was in hopes of using it on my skyhawk gt5 as an upgrade from the cns. Well aware a new intake will have to fabed up. Or atleast an adapter. Junk outboards are everywhere around here so it would be pretty easy to get one.

    few suggestions. feel free to tell me to shutup :)

    if you cant identify the carb easily, finding parts could be tricky. guessing and hoping isnt always the answer. then again, a quick trek to a marine mechanic could sort that out.

    manifold. no real issues except clearance. frame, clutch cable, that sort of stuff.

    cant really tell, but is it a diaphgram, or bowl? (ie, gravity fed) integral pump, or separate? fitting a pulse line is easy, but beware some carbs DO require a return line. extra plumbing to worry about. some require a fuel pump, or at least a pressure tap on the crank case.

    the most annoying part on fitting alternate carbs, in my mind, is cables. either it takes forever or its a five minute bodge job with some bent steel strap... oh, and air filters. if its a neat self contained affair, great, if you have to fab one up.... have fun checking out things like pvc pipe and lawnmower filters ;) worked on my old ct110 at any rate :) alloy plates and a small "donut" car filter? micro cyclonic filter free? oil bath? etc etc... imagination helps :)


    personally, if i found a nice cheap source of them...the walbro rotary barrel type carbs. WJ series? iunno. they just have the cable fitting fitted as standard. as do the old school slide types. hard to find them now!

    hmmmms. micro cyclonic.... i been getting into cyclones lately. the smaller they are, the smaller the particles removed. a small chamber can only flow so much. so a lot of little chambers will flow the same as one big one, but will remove the fine stuff. hence why dyson uses lots of tiny ones. anyways.

    they sorta use the idea on diesel a lot :)

    back to the thread... :)
