Carb questions etc ..

Post by Brendan65 »



Started on the carbs on my "running poorly on 3 cylinders" recent acquisition.
First thing I found was that the airbox breather hoses were switched. I wonder what effect this would have ?
The air filter is quite oily/dirty.



Then when removing the intake runners I noticed a lot of old sealant - is it normal to use this, or would the "O" ring/gasket be enough ?



Got the carbs out .. they smell like old gas. 8-)

i can't comment on the first pic because my '77 uses a slightly different air box.

people sometimes use sealant there if they are re-using old o-rings and are afraid of a potential leak; so no, sealant isn't normally required/recommended there, although i doubt it would hurt anything, and if you are using new o-rings the goo is completely unnecessary.

Yeah I'll remove all the crap and use new o-rings. I'll watch for leaks when it's up and running.
Thanks for the info !

If you haven't seen this you might find it informative and useful in your carb rebuild.

Looks like the primary jet was clogged in the non-running cylinder. There may have been other issues that I didn't notice, but the carbs were pretty clean. Apparently they were serviced not too long before I bought the bike - but there was some black scale in the bottom of that one bowl that flaked off quite easily, which I bet was the cause.

Anyway I'm happy ! :D

I did a "bench synch" and it seems to be running great as is, but I'll still use the vacuum gauges later ... a project for another day ! 8-)

Quick vid of it running :

Also found 2 of the 16 float bowl screws stripped. I snugged them up as best I could, no leaks yet. Yet another project for yet another day !! :mrgreen:
