All,
Yesterday I picked up a used rental Bluebird aerator with the B&S Intek 900 engine on it (122000 series).
It runs very well, though it surges at idle unless 1/4 - 1/2 choked.
I broke down the carb, cleaned it thoroughly. It's spotless now, in and out.
Upon tearing it down the second time, I realized something interesting - I saw no welch plugs inside the carb.
Are there not supposed to be two welch plugs covering the two round cavities? Is it possible this model carb has no welch plugs? Would the motor even be running this well without the welch plugs?
I also noticed what looks like no replaceable seat on the needle/seat assembly. Based upon the documentation I've been able to find, it doesn't look like there is a replaceable seat (the needle has a rubberized end on it).
Advice appreciated.
Thanks!
