Hey all, I am just about to put these carbs back together and think I have everything sourced that I need to do so. I am getting orings from cycleorings, bowl gaskets from z1enterprises (unless you have a better place), and the morgan carbtune.

I have been looking at the carb schematics I found on BikeCliff's site and one on BikeBandit but am unclear about 2 other parts I need.

The screw that holds the needle valve body in place. I destroyed the head and had to cut a slot in it to remove it. I would like to replace it but I am just not sure I am seeing the right one in the diagrams. Does anyone know where I can get one or what type/size/thread it is to replace it?

Also, looking at cycleorings site, when I pulled these things apart either I just didnt catch the washers/orings in the mixture valve, they were so deteriorated that they fell apart when i cleaned them, or they just werent there. Is that even possible that it could run with those in that condition? Or is there possibly something else I am missing?

Thanks!

The pilot screw washer and O-ring typically get stuck down inside the hole in the carb body. Make a small hook tool as detailed in the carb rebuild tutorial linked in my signature and you should be able to fish them out. Use an eye loupe or similar and make sure there is nothing stuck down inside the hole. If the washers are truly lost, you need some new ones.

The screw holding the float valve is listed on the OEM parts fishe. The part number suggests it's a M4 screw.

An alternative method for clearing out the mixture screw hole that I use all the time is a long drywall screw.

Just stick it in, push GENTLY, give it about 1/8 turn to the right, pull it out.

Depending on how stuck together the items are, you may get the spring the first time, the washer the second time and finally get the o-ring on the third time.
