View attachment 1715246037 As the post says, HELP please.
I have a 1968 340 fresh rebuild. Standard bore, .010 x .010 crank, heads all new with guides, valves, springs. I was able to reuse my factory 4 speed camshaft. I did not degree the cam. Factory iron externals. Exhaust, intake. Distributor is a rebuilt factory point. Was going to upgrade later.
I started the engine and it seems to be very happy, but will not run on the idle circuit. Carburetor is a 600cfm Edelbrock. When choke is closed it will idle.
So far, I tried a different carb Edelbrock. Timing is set at 10 btdc. Ran hot wire from battery to + of coil. Sprayed carb cleaner looking for leaks, pulled valve covers to ensure valves not hung open. Since I tried another carb and no difference I can eliminate carb issues. I retourqed intake thinking it may be sucking air from the underside.
I used search button and read for 2 hours. I am lost , any ideas?
