installed bbk and now it won't start

i guess i worded that wrong, is there really that much difference between the 28 & 30? i checked the way brent said to with taking the vari face off and the belt fits on the slide boss and comes all the way out to the edge of the rear pulley but its extremely tight. i also noticed how weak the contra spring is, so i think i'm gonna try a 1.5k contra spring and see how that works. but worse case senario i'll order me a slightly longer belt. i found a few other belts between what the two sizes that i've already got if i need them. they are all real close but range from a 760x16 to a 768x18. not sure what the angle #'s are because they weren't posted and the place was closed today to try and ask.

I don't think it would make much diffference changing 2 degrees.

ok, well i'm gonna try changing from the stock contra to a 1.5k yellow contra spring before i start throwing money at belts that may or may not work.
