ready to tackle my carbs again

Post by winguyjo »



i put my '77 on the back burner partly due to weather but mainly due to needing to step away from the frustration of trying to get the carbs right. the weather changes for the better starting tomorrow and i have started to re-assemble the carbs after yet another cleaning.

just one question ... i know that the placement of the washers on the sync screws is critical ... is this the correct set-up ? intuitively i would put one on each side of the spring but i am pretty dang sure that i read somewhere that this set-up i have in the photo is correct, and this is certainly the way they were originally.

thanks
joe

Hi Joe: I've just done the carbs on my '78, as I remember the washers go one each side of the spring.
In my opinion, if you leave your setup as is, the rounded head of the screw has no sense at all, for it is not contacting the lever concave seat.

hi gypsy, and thanks for the reply. i am almost certain that i have it the right way as shown in pic. hoping one of the experts will chime in. to me it would make sense to have one under each end of the spring, but then again, it looks like there definitely should be one under the head of the screw because if not, there might be a tendency to spread the arms of that "c" shaped lever.

this is from the naked goldwings site, and it would seem to confirm what i thought was the correct washer placement, so i am going with that,

put the carbs back in, and even though i bench tested them for leaks (none) they ran poorly, exhaust smoked badly, and eventually showed a lot of fuel in the plenum. took them out, carefully inspected floats, needles and seats and couldn't find a thing wrong. i think that the float needles on carbs 3 and 4 (they showed fuel in the venturi) got hung up in their bores during installation. i have had this happen on one carb several times, but never to two carbs at once.

this carb set tried my patience to the limit. on previous wings, a good cleaning, check the float height, bench test, bench synch and, for the most part, job done.

not this time. the carbs were pulled several times ... tears were shed, bad words were said

lessons learned :

1. have a CLEAN, WELL ORGANISED WORK AREA;
2. try to get the job done over a single weekend, not spread out over months, as was the case here. things get forgotten;
3. buy oem or randakks carb kits; nothing else.

bike is now rideable, just needs some synching and fine tuning of the pilot screws to really get it sounding/running properly. huge sigh of relief . :)

Thanks for the update. Your experience is a perfect example of what happens when trying to rebuild these carbs on the cheap. Not going to happen! Do it right or them over and over and over.
