I have a xp150 and the carbs need rebuilt due to lack of use. i got the kits and the clymer book. I have rebuilt carbs before so I'm not a total novice, but when attempting to remove the orafaces located in the float bowl to clean or replace as needed, the brass removal ears came apart on me. I used a screwdriver that fit properly but these guys were stuck very well. I only tried on 1 float bowl so far. I have another set of carbs but at 70$ for a bowl I don't want to ruin them. Is there a method to remove once the ears are gone? Have I ruined this Bowl? any help is appreciated. Is there a "secret" to getting them to release?
