I have a problem which has been recuring intermittently and now permanently. The engine starts normally and idles at about 1200 rpm. I does not come back to normal idle for a long time if at all. If I open the throttle in gear the max I can get out of it is 2200-2500rpm. I have pulled the carbs several times and cleaned them, thinking they may have had blocked jets. I have replaced the plugs, fuel pump and checked all air and fuel lines. I’m thinking it’s running to rich, but it’s not blowing a lot of smoke and doesn’t smell rich.
any suggestions?
 
"does not come back to normal idle for a long time if at all"

I would think that's related to the Prime Start enrichment system not closing all the way, or your link/sync wasn't done properly.
