wont spin

Just an FYI, the less power or IE torque the less the convertor will flash. Even though a convertor says 2200 it may be tight and only flash to say 2k or with a lot of torque maybe 2500 or so, also they have differant ratios in the convertors too. It sounds like you may need a little more convertor or a looser one.

Good reas on this topic;

Hope this helps? Also I would stay in the 625 AVS or AFB carb size and they the rods are easy to tune for better low end, too much air= less air speed thus= bogging at low rpms.

my 2 cents.

Good luck Ryan!
