1990 150 xr4 verticle to horizontal reed and carb change

[BASSCASTER]

hey everyone, just wanted to know if a 1997 reed housing, carb, and air box would be a direct bolt on to my 1990 xr4? 1997 is a 150 also. I've read the thread on doing the 200 front half swap and am toying with the idea of doing it, but right now I found a broken emulsion tube on my center wmh 1 A carb, and if I am not mistaken, the rebuild kits do not come with the emulsion tube......and as far as the swap for a 200 front half, exactly what do I need? Thanks all!

im assuming its a fat block if not you will need a 2.4 horizontal front crank mains aint the same size and 2.5 wont bolt up to it
