Need info for a Poulan Pro 422 leaf blower

I could use some help finding information for a Poulan Pro 422 leaf blower. I already ordered a rebuild kit for the Walbro WA207A carb. I need an owner's manual or, better yet, a shop manual for the blower. I could also use some information on the basic carburator settings. Thanks in advance for any help provided.

You can get the IPL and OM on the Poulan site, (when it's working)

Usually, the L and H needles can be turned CCW from lightly seated 1 1/2 turns to get it started.

Glen, I found the IPL on the Poulan site. The server for the OM appears to be down at the present time. I will try again later. The needle settings worked for me on a chainsaw with a Walbro carb. I'll use the settings after the rebuild. Thanks for the feedback.

Still waiting for Poulan (Husqvarna as it turns out) technical support to respond to my inquiry for an owner's manual. In the mean time, I cleaned the carburator and reassembled with a new carb kit. The blower has five throttle settings: full choke, half choke, idle, half throttle, full throttle. The blower starts and idles OK, but does not produce full RPM when set to full throttle. There does not appear to be any fuel restrictions. Adjusted the high speed jet without any problems. Any suggestions as to why the low RPM on the full throttle position?

Is it possible the spark arrester in the exhaust is blocked enough that you can't get full throttle??? Roger

Roger, Thanks for the comment. I intend to check the spark arrestor this weekend. It is a real pain to access the muffler on this blower. I will also check the security of the cylinder at the same time.

Checked the spark arrestor and exhaust port. There was some minor residue, but not enough to cause a restriction. Reassembled blower without checking the cylinder bolts. Forgot due to being in a hurry. Used fresh gas with synthetic 2 cycle oil at 32:1 ratio. Blower starts OK and will run on all five throttle positions, but still will not operate at full RPM. Thinking that maybe I should have soaked the carb instead of using spray when cleaning the carb before rebuild. Other than that, I am getting to the point of diminishing returns.
