String Trimmers

I use my Poulan Pro string trimmer for household purposes only i.e. not for commercial, professional, rental or income producing purposes.
Does it appear that my string trimmer would be covered under the original warranty for this product for the problem listed below?
If the following problem can not be corrected, is there any way I can return this string trimmer or get a refund? I also purchased the edger attachment for this string trimmer which also cuts great when the string trimmer is working properly.

I purchased a Poulan Pro string trimmer Model # PP335 966062901 6/14/2011. I've had to bring it in to the repair shop twice already because it would not start. The problem was corrected the first time by adjusting the carburetor. The second time the problem was corrected by changing the spark plug which had become corroded apparently from the fuel mixture.
Yesterday the string trimmer started but died whenever I tried to cut with it. Both the air filter and spark plug were covered with gas/oil mixture. The 2 previous times I used the string trimmer, my clothes smelled strongly of the string trimmer fuel mixture-this had never happened previously.
My questions: Why is the gas/fuel mixture fouling the air filter and spark plug? Is there anything that can be done to permanently correct the problem? Why do my clothes smell like fuel mixture after using the Poulan Pro?
I love the way this stringtrimmer cuts when it's working but I don't want to have gas all over my clothes after I use it nor do I wish to keep returning to my authorized service dealer for repairs. Thanks for any info.

I recently chatted with a representative from Amazon.com, and he directed me to this site for a resolution, since I have a 2 year warranty on my Poulan Pro trimmer, which I recently had at a Poulan authorized service dealer, Groton Cycle Center, for over 6 weeks, after which time they were unable to obtain a coil, which they believed was the issue (would not start). I have a Poulan Pro 966774301 4 cycle string trimmer, model 132005400612, SN 132005400419, shipped on June 18, 2015. Your assistance will be greatly appreciated. Thank you, Jolene Perkins.

I have a Poulan Pro PPB335 trimmer and the recoil starter is the poorest design ever I have had to replace the spring (part # 545008013) 3 times and now the end of the crankshaft has broke off. I purchased this trimmer 4/2010 and it never work right from day one Walmart replaced it once but no longer carry this model. The reason I purchased this model was I could switch out the trimming head to other attachments that I purchased separately like the tiller. When I call the 800# they refer me back to the place of purchase. How do I get Poulan to stand behind their product?

My new Poulan Pro string trimmer/chainsaw starts fine in start position, but even after allowing engine to warm-up, it will lose power and stall when I place lever in "run" position and attempt to use trigger throttle control. This unit is only two weeks old, I can only use it in "start" lever position, please advise!

Thank you,
