Having a hard time getting my A4 to idle down. The motor only runs at low rpm with the choke on. The idle mixture screw is almost all the way down - and it still won't idle. When throttling off idle - there is a bit of a bog before the rpm picks up. I rebuilt the carb over the winter - I suspect that the idle circuit if plugged up.
Last night I sprayed carb clean around the carb and no rpm changes - I assume that I have no leaks. Although I did add a PCV system - anything to be concerned about there?
How much vacuum should this engine pull at idle?
Any tips, tricks or tools (brass wire etc) to cleaning out the idle circuit or to verify that it has fuel flow?
Thanks
