so i guess the 2620 will have slightly lesser runtime than the 2601 but have a little more top end

Easy actually, ain't it?

my mtx4r 'double' brake disk is hitting! my 353 carburetor and 'grinding' it off...

any problem if i were to grind off a bit of my 353 carburetor so that tha brake disk doesn't touch it anymore ? (i am not sure how thick is the carburetor wall). do not want to increase the engine height.

appreciate any advice . please help thanks

guess only the mtx4 with the very thick mugen disk brake will encounter this thing.. anyway, will try to rotate it again.. anyway, no big problem ...

thanks.
