Carb Locking Washers

[Toolmaker Tim]

I did it to myself. When I took the set of carbs for my F apart to rebuild I replaced the butterfly shaft seals. I took the thin flat washers into work and made them nice and flat. Then the gremlins stole them. I have fricking tore everything apart looking for them, no luck. Soooo. Is it a big deal to just use regular lock washers in their place? It doesn't look right. I know because I have a rack of 80/81 carbs that have them. Any ideas, opinions, or concerns about using regular lock washers?

Do you mean for the bowls and the caps over the diaphrams?? if so, then I see no problems.

Tim, skip regular lockwashers and use some locktite on the shaft nuts....

No Don, it's the shafts that the brass butterflys slide thru. I ground the phillips head screw ends off because they are staked, so I could replace the shaft seals. I replaced the butterfly screws with stainless flathead allen screws. When I went to install the linkage between the carbs, the bendable washers were so bent up I decided to fix them by squeezing them in a grinding vise. That's when the gremlins stole them.

Steve, I thought of that, but was concerned that fuel,heat, and vibration would work them loose. I figured that is why Mother Yamaha put them on there in the first place. Sort of like safety wire or a cotter pin. I am guessing you mean the red automotive loctite is the type to use.

The blue should be more than enough; don't use the red unless you really want those puppies on there. I also own Harleys (which vibrate way more than these do! Blue Locktite is My Friend!! I buy the big bottle ) and haven't had any fasteners that I've used that on come loose, including ones where I've purposely ditched the lockwasher. That stuff is great...

Also the chemical of choice on the butterfly screws..
