Hello all together.
I bet there were lots of carb issues but I hope to challenge you with this one!
71 Sport Fury 383 CARTER AVS 4BBL
Ignition checked and reset to 8-9 degress before tdc
Carb rebuild and adjusted (fast idle speed cam, vacuum kick, acc pump, sec throttle lever, sec air valve etc pp)
Problem 1: CHOKE valve goes wide open right away while cranking cold engine
Car won´t start without keeping choke valve almost closed MANUALLY BY HAND because it wide opens while cranking the cold engine and the engine dies right away ! Starts without any problem if holding choke valve almost closed by hand till it warmed up and runs good after that.
Problem 2.
WOT not possibe without backfiring or spitting some gas out of the bowls. Did turn out the mixure screws while checking for highest vaccum via gauge (plugged in at choke outlet vaccum port . Got 15hg while idling) WIth choke plugged off WOT with the new screw adjustment ( very far turned out ) is almost 100% with no backfire and good but with choke assembled and attacjed WOT is doing hickups/dies and sometimes backfiring after 2-3 times WOT in a row.
Hope I did describe it detailed enough. If not just ask .
I am VERY excited what you guys will tell me because I am at the end of my carb knowledge.
SO lets go
