I wonder if it is running rich since I haven't made any adjustments after putting new pipes and removing AI earlier this year?
RE this question your concern should be that it would be running lean.
RE the length of time to start, the others have covered it well. Re the choke and rolling the throttle before starting her up. Members seem to think that rolling the throttle before ignition is one reason airboxes explode. Don't do it! Re the choke/enricher, full choke subtracting as much as you can before ignition. What? Full choke then push it in about 1/10 to 1/4 before starting. As with rolling the throttle, members seem to think that a full choke (warmer climates than yours though) are a cause of backfires/airbox explosions.
Even on cooler mornings, I'll use 3/4 choke, wait 10 seconds then letting off the choke all the way, while keeping her running by using the throttle. The less you use the choke the better. Guidelines only, as some morns I have to use full choke!
