Is there a simple way to disconnect the governor arm from the carborator? I've removed the bolts that hold the carb on but it won't slide off (It needs cleaned big time) because the of the linkage to the governor arm (wire rod and spring).  The shop manual says to remove one of the two screws that hold it on, but I'm not sure which one should be removed or what will happen to the governor if I do remove them.  I have heard that governors are really hard to adjust and I was trying to avoid that agrevation.  I've labels the two screws "A" and "B"  (one of them is really a bolt).

Unscrew the 2 bolts of the carburator that goes to the intake and disconnect fuel line lift up the crab you will easely get the rod of the governor hole without bent it. that how I do

good luck

Denis, the carb is held on a pair of long rods (arms) and carb's linkage to the governor arm will not let me slide it off  (thank you Yamaha).  I could bend the long governor arm (I suppose) but there's no guarante that I'll ever get it stranght again.  I am not very familiar with the two screws.  I think that screw "A" is acually the shaft to the governor but I'm not sure.  I have no clue what the other screw "B" (really a bolt) does.  I keep spraying both down with BP Blaster.  I love that stuff.

"B" is the clamp FOr the Governor rod "A"

I would take both the nuts from the intake manifold and tighten them against  each other  on one of the carb studs "double nut",   then unscrew the stud from the engine case.

No, not on this carb.  The rods are just long enough to get one small nut on there. No hope in getting two nuts on there. But thanks

I see what you mean, it's yamaha carb okay I understand, I use to work on walbro or tecumseh well let me try to find some documentation for those carb I'll be back soon.

At this point I would say bend the arm of the governor,  about 45 degrees.

Hold the it with two pairs of needle nose,  bend it just below the link holes, use the 2nd to below the first about an inch below to stablize the rest of the arm so the whole thing does not twist..

You aren't putting this thing in a classic Yamaha show are you?  :)

Is this a "TK" carb?

Good Luck,

If you use rubber hose over the plyers,  you won't put any teeth marks on the arm,   those arms should bend easy,   and bend back with no problems.

Or you could just mark the Govorner shaft and take it off,   They are not hard to set,  just like any other govenor..

Good Luck

Yeah,  Funny round little circle with "TK" in it,  (rounded edged letters)....I thought I saw the logo in the photo..

What model of engine is this? what is it on...  I can see it is gummed up in the photo.   and has not run for sometime.

....Brown fuel gum deposits under the choke butterfly..

Is the carburetor's model number also printed ?  I'd like to find a rebuild kit or a direct replacement.
