318 dodge dart stumbles 5000rpm

Do we have 2 different dicussions going on here - the 1st tread said he had a 650 Holley, then SafetyFifth says he has a 2bbl carb - a 650 Holley is a 4bbl which has
"secondaries" - 2bbl carbs only have primaries. For the 2bbl carb you can probably
find the carb listed on the web and look up instructions for it's rebuild kit - should tell
you how to adjust the float and such. Holley floats are very easy to adjust.
