right Team Vertex 26 and Vertex 21 are not the same, if by not the same I mean identical then yes, not the same. The only difference is the stamp on the side of the case, I have them here side by side and even swapped out carbs on accident while cleaning. Also, has anybody painted their engines? I put two cotes of high temp black spray paint for outdoor grills on my sh engine and it came out pretty good, does not come off with any of the regular cleaning chems either, only scratches off for now.
