Alright, remember that 2-Stroke motors are meant to do 2 things:
Break down, then Frustrate you.
So, here we go: (Electrical)
Rotor Magnets, Magneto (ignition coil), Spark Plug Wire, Spark Plug, Spark Plug Ground (Cylinder Head).
In that order!
Check your "fire" from the Magneto:
1. Check your Kill Switch. In other words, leave everything normal, and unhook it. Did she start? Kill Switch it is! Kill Switch/Wire comes from the Magneto (single wire/ground) to the Switch itself. So check that wire AT the Magneto (Is it loose and grounding out? Is the Kill Switch grounding you out where it is, because of crud, junk, or because it is touching the block when it is not supposed to?)
2. Check your Spark Plug Wire. Easy, unook it from the plug, stick your finger in, give it a crank (non-MultiMeter way). Did you get shocked? Then it ain't your Plug Wire and Magneto!
With a Multi-/Volt Meter, simply hook her up, and check for juice WHEN you pull the rope. If you got juice, it ain't your Plug Wire or Magneto!
Checking Spark the "normal" way: Grab the Plug with a pair of insulated pliers, hold the plug end against the cylinder head, and pull your rope. Any Spark? What color?
3. STILL no fire. It leaves: Magneto and Plug Wire.
Luckily, they are both in the same place! Tear your blower down, and check to see if the Magneto has slipped out of place (gap is WAY out), or if the Plug Wire has worn to the point it is grounding you out. While you are there, check your Kill Switch wire, to see if she is grounding you out then and there.
4. STILL no fire. That means: Magneto Failing, or Magneto JUNK.
Buy another one, replace it! (Or steal one from another junk Blower/Weedeater. These things are fairly standard, and easy!)
Or, Bad Plug Wire. Meaning she has failed out on you.
Wait......that means: Replace your Magneto! Lucky the things are built together right?
I have tried all the above and then some, replaced the magneto and still no spark, new plug, no spark, are gap adjusted to .012 to .008 still no spark. Weed eater is made by Poulan, it's strange, they both have the same problems. Personally I believe they have design problems.
Plug for the BVM200 should be set to .025, per manual.

I have a new Poulan Prov leaf blower model BVM 200VS. I bought last Nov and used it at most 10 times.
It will not start. Removed the spark pug, the cylinder is wet. There is no spark. Changed sprak plugs,,still no spark. Suggestions?
Don't know if the problem has been solved.
Have you reset the gap of the magneto? Set the gap aprox. 0.010" or 2 sheet of the 8x10" regular paper thickness.
Loosen srews, insert the papers in the gap, drop the coil extract to the wheel, re-tighten the screw set, remove the papers. If the firing part are in good condition, they should produce a spark.
If no spart your magneto is bad or need ajusting you will have take the blower aprt to get to the magneto the spark plug wire leads to the magneto /use a peice of note book paper to ajust the gap..if that does not work the magneto is bad /buy a new blower not a poulan.

Ok. Good job on doing what you could, right off! The simplest things are the most overlooked, and the most unforgiving.
So, you know your plug is wet, so you got some fuel flow.
Now let's figure out the plug no-fire problem. (This is under the assumption you haven't beat on this blower with a sledge-hammer at one point. The whole "key-way" is fried thing.)
1. Grab ahold of that plug THEN crank away. One time will tell you yes or no on spark. No, I am not joking, and yes, it is better than staring at the end of a plug and wondering if your eyes are bad.
In fact, better than a cup of coffee......in a bad way.
2. Check your kill switch. It is either: Grounding, or Open (open like it should be, UNTIL you push it, click it, or slide it, whatever you got). One CHEAP and fast way: Unhook the kill switch.
Then crank away. No spark? Not the kill switch then!
3. Check your spark plug GROUND. Let's say you got some shocking results from grabbing onto that bad boy. NOW check where the plug meets the cylinder head when she is screwed down in there. Believe it or not.....if it is funky, she won't ground right!
Hence, no worky.
4. You got no spark at all.....STILL. Let's look over your Spark Plug WIRE. Is she wore through? Is SHE grounding out? Has she heat failed? Then do #5.
5. STILL no spark. Let's check the last 2 things......
Rotor Magnets, and Magneto (ignition coil).
IF you have a volt/multi-meter, hook her up to the plug wire. No juice = Bad Magneto, or Bad Plug Wire. SOME juice = Good Magneto, but Bad Plug Wire (in some mowers/weedeaters, etc., remember that the Magneto is where the kill switch hooks too.
See if it is somehow grounding you out, by being loose but still touching the cylinder, etc.)
6. Failing Magneto. This can happen, and it does. You get SOME juice, just not ENOUGH juice. 2-Strokes make a lot of heat, even Magneto's give up the ghost after a while, sometimes. In this case, find a replacement!

Poulan Pro BMV200LE. Leaf Blower.
No spark, replaced plug, still no spark. What would I have to replace?
Thanks,

Coil and module is one unit. You can buy coil on ebay for about 30 dollars. When putting new on roll piston to top center and put a business card between coil and the pickup on the crankshaft. Tighten screws and remove card. Put back together
