Mikuni TMX 38mm Block Seal Issue

Late model KTM/Husky 2-strokes are fitted standard with Mikuni TMX 38mm carburetors from year model 2017. However the block seal appears to be a very poor design and causes a leak, impacting idle and bottom end performance. This video shows how to disassemble the carburetor and where the block seal is located. I personally no longer use the Mikuni carburetor on my 2017 250 EXC, but thought it would be of interest to others who are still using the Mikuni.
