Put the money in another carb. A Holley or any of the other Eddy offerings is going to work out better.

You can take this current carb apart and look for crap left in it, some people have said they had junk in their brand new carb.

You might need stiffer springs, it may be sucking the rods down and blocking the jets for a sec. Would be nice to try somebody elses springs in it before you drop the money on the strip kit.
