will it fit? will the h30pict carb be better than the 28pict i have

It will fit straight on, the only difference is the 1500 manifold is thicker by a tiny bit.

ok, i noticed the OD of the pipe was bigger, thanks

check the main jet as a 1500 carb i bought new that i put on a 1300 i've got had a 120main where the 1300 had a 125main jet.. go figure.
