carb removal help
« on: April 20, 2017, 08:39:11 AM »
Could anyone provide me with instructions on how to easily remove the carbs from the GTR 350? I have gas pouring out of each side now after sitting for the winter. Also, would anyone be interested in buying my 350? I have moved on to other interest and am willing to part ways with the bike. It's a 1968 and in very good condition other than the carbs leaking and the battery cover scratched from falling off last summer. It also has clean NH title.

My thought would be that you can cure the leak by just sliding the carbs off the intake tubes and tilting them enough to remove the bottom float bowl.
First guess is that the needle valves got just enough gasoline "varnish" to stick in the open (down) position and not move up to close flow when the bowls are up.
Second guess is that both brass floats have developed a crack in the solder seam and don't float anymore. Not likely, but not impossible.
You don't need to disconnect cables from the carb for troubleshooting either of those guesses.

              Sometimes a gentle tap or two on the carb with a block of wood is enough to free up those sticky floats or needle valves after standing over winter.
Growing old is compulsory, Growing up is optional.

I must be doing something wrong because I cant move them out to get at the back screws of the float bowl.

Did you loosen the spigot clamp screw on the inside? You remove the rubber plug in the front of the carb enclosure and reach in with a flat-bladed screwdriver. Then pull and twist to get the carb to slide off the spigot. On the right side, you may also need to remove or pull the oil pump control cable up and out of the way to get the carb off.
