Poulan Pro 31cc weedeater hard start, blue exhaust

I recently acquired a 31cc poulan pro weedeater, I got it because it was exactly like my craftsman I was trying to repair. It ran great at first so did not use it for parts. It did have the same issue I always had with my other 2 stroke weedeater, it hesitated and sometimes stalled when opening the throttle. Then one day it quit running. I found out I had a little too much oil in the gas, just enough to foul the plug and the exhaust was carboned up, so I bought a new plug, cleaned everything, replaced the fuel lines, decarboned the exhaust and reinstalled everything. Now I have the problem that it is hard to start and will not run without the choke on, but blows alot of blue exhaust, seems like too much oil, but I am certain it wasn't. the plug oil fouled again though, replaced it, and same problem, but if I kick off the choke it dies. It has good spark, and I have repaired these many times, but this has me baffled, as there is no damage inside the cylinders.

This worked for me but I had the problem with not reving up, but can't hurt to try. On the muffler there is a spark arrester screen pull it out and see if that doesn't cure the problem. I have a 33cc poulan weed eater runs like a champ........two-dogs

I thought the same, tried it, no luck. I tried seafoam too, trying a new plug again, it is obviously getting fuel so the carb is ok, my try my old one though

If it dies when you take the choke off, it's not getting enough fuel. The carb needs work.

I would think the same thing in most situations, however, it is obvious that it is getting fuel due to wet plugs and when I try to rev it up, I have to feather the throttle, but in a lean condition on a 2 stroke they tend to rev up higher, opposite of a 4 stroke. I just can't figure out why it is suddenly running rich, I am going to try swapping carbs with my old one, but it just has me confused, especially blowing exhaust like too much oil in the gas.
