Anyone out there used a Summit MO8600VS - 600 CFM carb on their 292 or 312 y- block?  I purchased this and appeared to maybe too much for me set up   I have a pretty basic set 292 with a 57 dizzy, pterionic II, Runs and Idel's good but at WOT stumbles. Pull plugs all show black running to rich.  So, thinking I should go to lower jets.  Looking for some direction.  Not a Carb. guy.
