Whats wrong with that picture? I just removed the filter, seen that crap in it and took the picture. I dont know what a a HD2 filter is, but I'm sure its whatever came stock on it. I'll photo it tomorrow.
It's awful odd for a 441 filter to allow so much dust to get to the carb. I punish mine at work. I hardly have time to clean the filter until lunchtime and at the end of day. The filter barely even has any dust on it, and it's very clean under the filter. Seems the mating surfaces could be damaged on the filter or the carb. Like Mike said, the 441 is setup with an air injection like Husky saws. The filters are actually hard to dirty up.
The HD2 filter is the newest one Stihl is using. They're very good filters. Black and chrome and should have HD2 wrote on it somewhere.
