I purchased the carb already rebuilt. My friend helped me adjust it when we first got the car running. Seemed to run fine for normal driving, but after a few WOT runs started hesitating at higher rpms , and then from a stop to WOT started bogging . Then seems to load up and not want to stay running and sometimes dies,and hard to restart. I smelled fuel and found the baseplate and top gasket soaked in fuel. I haven't driven since. Sorry, Don't know any details on the rebuild.
