Quick question carb rebuild

[spy1309]

I bought at least 3 carb rebuild kits for my 1960 Johnson 40hp motor, don't ask why i got 3, for almost a year I try to get the engine to run good and I can't.
Now in all the manuals they say that for the low speed needle to use 2 fiber washers and one nylon washer, same for high speed needle.
In all 3 kits I got there are 6 fiber washers no nylon washers what so ever.
It is almost impossible to fit 3 fiber washers and be able to fit the packing nut.
What gives? Why there are no nylon washers?
I used only 2 fiber washers and then the packing nut, now I know if you get air leaks your idle will be messed up and idle is the one I have problems with.
Also the gasket for the main nozzle is a cork made one and does not fit the nozzle is 2 small as diameter, if you try to force it, it will brake, I went to local Menards and I got a rubber washer who fits alot better.
Any advice will be appreciated.

Re: Quick question carb rebuild

The cork nozzle gasket is simply a tight fit and is the proper one.... if you purchased the right kit(s). Sounds like possibly those kits might be for the smaller engines.... that would account for the smaller cork gasket BUT if this were the case, the body gasket would also be wrong.

You don't need the nylon washers. Using all fiber washers is the proper method.

Using more than 2 fiber washers makes it impossible to install the brass locking nuts? Did you remove the old washers? Normally 4 washers will fit the high speed needle valve easily.
