Now that the mornings here are in the 30's and 40's, the Royale was nearly impossible to start. I found that the choke was only closing about half way, so I adjusted it to close fully when cold. Then it wouldn't open fully when warmed up. So I adjusted it to fully open when warm, and you guessed it, it wouldn't close more than about 3/4 when cold.
I had a spare bi-metal coil so I swapped them. No difference. I disconnected and blew out the heater tube and the port on the carb, and they are clear. Checked the pull-off with an external vacuum source and it works fine. All part move freely.
I have rebuilt many Q-Jets but most had the small choke coils in the metal can that bolted to the intake manifold. This is the first integrated hot air one I have dealt with. Am I missing something?
For what it's worth, to have the choke close fully the index line is on the last mark of "lean". To open fully it is about 1/8th of a turn beyond lean. This leads me to believe that maybe something isn't lined up correctly inside the choke housing, but it looks fine.
Sorry for the long winded post.
