Poulan Wild Thing and Wood Shark Saws try to run, but stall down.
Both saws have run well for years. Started to have carb problems with both. Rebuilt carbs on both saws, would run ok for awhile. Replaced fuel lines, new plugs never got any better. Purchased a new carb for both saws, thought they just had worn out carbs. With a new carb the Wild Thing run good for a few days. Now with a new carb they will both crank and try to run, but act like they are sucking air or have a crack in the case. Have the Wood Shark took a part, have not found anything. Cold they be sucking air at the base gaskets or at the bearings? Are they a rebuild kit? Would it cost more than the saws are worth?

Re: Poulan Wild Thing and Wood Shark Saws try to run, but...
They could be sucking gas from the base gasket, head gasket or the bearings. Also, Check your flywheel very wheel and your armuter, if either are rusty then they need some sand paper to help create spark. There are rebuild kits and they are cheap. I always tell my customers to fix there older machines cause the new ones are **** and they leak everywhere and if anything brakes they are REALLY expensive to repair. You can get a rebuild kit whole machine for about 65 dollars

If not already done replace the fuel filter in the tank, it is obviously fuel starvation, if no better increase the the fuel mixture on the H and L screws ( turn anti clockwise 1/4 turn on each to start with)
It is running lean, they always need to run a little on the rich side free running, once the engine is loaded it will then need the excess fuel, it runs ok without the bar and chain because there is no load, start by replacing the fuel filter in the fuel tank, check the fuel hose up to the carb for signs of fuel leakage, replace if reqired, if the carb has standard adjuster screws, increase the H screw by 1/4 turn out ( anto clockwise ) this will richen the mixture.
Get some sta-bil fuel stabilizer. add twice the amount recommended on the bottle for storage to your mixed gas. Empty out chainsaw tank and refill with the new mix. Rub for 2 minutes, then shut off. Remove cover over carb and spray inside carb, soaking it down good and cleaning all internal surfaces visible - allow to sit overnight. Next day Spray down carb with carb cleaner for about 15 seconds. Start saw, allowing 2 minutes to warm up and reduce choke. If saw stalls, restart and spray inside carb as it runs with choke on - keep motor at the highest rpms you can as you spray - spray in 2 second bursts, not allowing motor to stall from spray. If it stalls, change sparkplug and try again. You have varnish build up in the carb and are trying to remove it so the carb will work without the choke. This may take some time but it is the exact procedure I used for my Poulan Team Realtree last spring - I spent about an hour spraying and staring before it ran without the choke. Good luck!!
I own the Poulan Chain Saw the Wild Thing. Replaced the spark plug and fuel filter and made a fresh batch of gasoline mix and I am still having a hard time getting it started. I had the exact same problem last fall. Repair shop told me it was flooded. If this is the case how do I resolve the problem. I took the plug out and it was dry.
