i have a weird problem with an 87 phazer with a 480 f/c. the sled will idle great but have a slight bog and it will go away when you engage the choke and richen the mixture. i have cleaned these carbs numerous times. It will also act funny a lot and is untuneable. the changes are so fast i was thinking maybe spark...it has spark at all times so maybe it's weak? stator or cdi unit? I did compressions and a leakdown test and all seals are holding pressure.
any suggestions?
thanks
