So it spits and sputters. Has like 95+ compression. Piston not scored. I put gas in and pulled quire a few times. Spark plug hand tight. Noticed gas coming out at spark plug and exhaust. Pulled plug. Pulled start. Gas blew out constantly. Took carb covers off all looks fine needle seat looks fine.
Poulan 2150 flooding bad

Sounds like a seriously flooded engine, do a search on how to COMPLETELY clean it out and then do a pressure test on the carb, the inlet valve is probably not seating due to a internal carb problems such as control lever height, stiff diaphragm, gasket on wrong side, tip of the inlet valve bad or the valve seat needs cleaning, etc.
Compression way low...... Time to pressure test and find the leak or leaks!
You said compression is 95+, do you know high it will go if you keep pulling it over? If it will hit 110psi with a known accurate gauge, that's about the minimum for it to run but still too low for "like new" power.
Carb stuff looks fine. Engine was not flooded prior to trying to start it. My tester leaks a little i usually judge by how fast it goes over 90. Im pretty sure ive had weed wackers run at 90. On any 2 stroke i usually squirt gas in carb and hold throttle to see if it revs. Then i do the work to get it running right.
Dont know how to pressure test
Not the same model as your saw but the theory still applies....
Low compression will tell you "time for some rings and stuff" that doesn't address the flooding. Did it run fine yesterday or did someone give you a project saw yesterday. You want answers to to many unknowns. You can shortcut the carb testing from post #2 by putting in a a carb kit. do some utube vids on carb rebuilding/cleaning and what NOT TO DO. Post #2 and #4 are a Good start and cross referencing
your saw to Ebay listings or google should help get the right carb kit ordered or buy a cheap chinese carb ready to swap out and see what happens. if it works do NOT throw away the original carb but rebuild it as the cheapie is cheap for a reason.
