Hello, I have a Poulan Pro leaf blower, Model bvm200vs. Today while blowing leaves a string that was hanging from my jacket was sucked in the blower and it shut me down.
I am unsure of how to get to the string. the fin in larger than the hole.
Should I try to remove that side of the blower to get to the string? I don't see any other way.

In short, yes. The housing should split into 2 major pieces with a half-dozen screws. You should then be looking at the impeller wheel. The string may be in front of the wheel, or wound 'round the shaft behind the wheel. The wheel itself is removeable. The nut retaining it may be left-hand threaded. It will turn in the direction of engine rotation to loosen.

If the string's behind the blower wheel, be very careful not to damage the crank shaft seal when removing it. If the seal is damaged, replace it before reassembling. This seal is critical to good engine operation (it'll run lean without it).

Should be no big deal, though.

"This seal is critical to good engine operation (it'll run lean without it)."

And two-strokes DO NOT LIKE IT when they run lean... Especially the pistons...

thanks, appreciated

Jason, the propeller seemed to be tight on the shaft, my question if I need to remove it how could I do that?
I can see that the string is not in the front, so it must be behind.

There's an exploded diagram of the machine, will give you an idea how it comes apart.

The impeller is retained by a single nut. Be careful not to damage the impeller when removing the nut (if you haven't removed it already). The nut will remove in the direction of rotation of the engine... By the looks of it, it's right-hand (normal) thread.

If the nut is very tight, remove the sparkplug and stuff about as much rope into the plug hole as you can. This will lock the engine without doing damage, and allow you to reef onthe nut.

Once the nut's off, the impeller is "keyed" to the shaft by having a flat spot on the shaft and corresponding one ont he impeller. This means it won't turn on the shaft more than a couple degrees. Use penetrating lube and gently rock the impeller back and forth while pulling and it should come loose. if you do damage the impeller, it's impossibly cheap (under $4!).

I really appreciate you assisting me on this project. I planned to remove the screws so I could look behind the propeller, but what I thought was a phillips head or a flat screw head is not either one.
what is holding the parts together has a round hole, I have no idea what they are not star heads square heads. I'm at a standstill at this time.
I know my description of whatever they are is not very good but if you would have some idea would appreciate your input.

Terp, I don't know what to tell you. I'd think they'd be allen head (hex head) screws, but would be unsurprised to find torx (star) head.

Found a better IPL illustration, this one zoomable...

The same screw part numbers are used on various other machines (by googling screw part number hoping for a description), including chainsaws etc. I expect they are infact torx or allen.

Terpland...take a pic of it and help us out..picture's worth a thousand words...

If it's >> THIS ONE << then it looks like it's an allen head...



Thought - if someone previously used the wrong wrench, could be the screw is damaged and appears "round" instead of hex/allen.
