GREAT NEWS !
I was able to save this WR 400 carb with a little luck and inginuity
On a hunch, after studying the pictures of the 2 mid case seals available from different sources, i was pretty sure the outer perimeter portion of the large main seal was not going to fit properly, but after looking at my mid section seals outer portion, i felt mine was definately reuseable.
My inner oval shaped seals were the ones that were destroyed. Fuel is in direct contact with these 2 inner oval seals. The large outer portion of the seal is more of a dirt/dust seal between the carb sections and never makes direct contact with fuel.
So i ordered both available seal kits from jdjetting and once i receaved them and laid the new seal against my old, i could definatly see the outer perimeter shape is not the same. But the 2 inner seals would work !!!
So with magnifying reader glasses on, i used a sharp straight pick to work the slimy sticky old inner seals out of there grooves. Then cleaned residue with a small brass brush.
I cut both inner oval seals off the 2 main seals and matched up 2 that would work .! Yahoo.!!
The 2 inner oval seals are not the same on each main gasket. Out of each pair, one would be slightly longer . I needed the 2 hole oval seal off of one main gasket since it was longer, and the 3 hole main seal off the other main gasket since it was shorter.
The "bubble seal" and the 2 tower seals that came with the kit fit perfectly with no problems.
To be sure the oval seals would stay in place during carb assembly, i took a tube of black 3m gasket adhesive, and put a little drip on a peice of paper and smeared it around with my finger to about the size of a quarter, set the inner oval seals, one at a time into the thin layer of adhesive then quickly lifted it out and pressed into into the midsection grooves. It worked great..
Got it together tonight and rode it around awhile. It rips ! No bog, no hesitation, instant throttle response..
Hope this helps someone who is in my same situitaion. $63 total invested from JDJetting and didnt have to buy a $600 + carb ..
You have some extra tower seals left over and one whole main midsection seal left over too. Have to order both kits to get all the seals you need.
