No start condition. Good spark, new plug, gap set at .030. fresh fuel/oil, cleaned carb, getting fuel to plug. Plug gets wet after a few pulls.Tried choke, no choke, throttle and no throttle starting. The most I can get it to do, is spit out of the carb throat.

I would suggest finding an inline checker so you can visualize the spark without getting shocked for damaging the plug boot.
If your carb is working then when you take out your spark plug it should be covered with fuel. This could be a sign of no spark or it might be a sign of a dirty air filter causing an extreme rich condition. Try starting the saw with a clean plug and no air filter in place to rule this out. If it is dry you either have a fuel line issue or a blocked exhaust. Chain saws have spark arresting screens on them that can load up with unburnt fuel and oil *(from a bad carb or blocked air filter) be safe and good luck!
Gap the plug at .030 What is most likely the main problem is whatever gas sat in the carb. Even with fresh gas there will be some old gas still in the float bowl. You may be able to drain the bowl and be OK but I have a feeling that the carb will need to come off and be disassembled and cleaned properly. You can try spraying carb cleaner (I dislike starting fluid as it is too volatile and carb cleaner does just as well in this instance) into the carb/intake. Remove the air filter, open the choke, and spray the carb cleaner in through that way if possible. You can actually keep an engine running by spraying with short bursts. Even by just spraying once you should be able to get the engine to start. If it does start but then will not stay running without spraying more into the engine then it is a carb problem.
Is your spark plug wet when you pull it out? If so then it may be fludding on you, If it's dry then your carb may be gunked up from old fuel setting in carb and lines it also can plug you fuel filter. after checking all these, check your compression and also take your spark plug out and look inside the hole at cylinder foe bad scores or scratches in the wall of the cylinder, you should also pull muffler off and check cylinder that way too, you may be low on compression. Another thing you could try is your air filter, is it plugged with sawdust, take off and try that , then try carb clean short blasts into carb and try to start, then work choke back and forth keeping it running to help **** some fresh gas through carb, all else fails pull carb and dissasemble and clean. Good Luck
First of all make sure the air filter is clean. Next I would dunp the gas out of the saw and put fresh gasoline oil mixture back in the fuel tank. Maybe a little condensation water got in the fuel you had in the tank.
Start with basic stuff first, drain the fuel tank and re fill with clean fuel oil mix, press the purge bulb ten or so times to pull the fresh fuel into the carb, now try again, if no better remove the spark plug and check for a spark ( make sure the ignition switch is on ) no spark try a new plug, still no spark check for wires shorting out, if ok replace the ignition unit, if it has a good spark is the plug getting wet with fuel, if not it may have a blockage in the carb, this will require a carb re build, if the plug is wet remove the muffler and check the condition of the piston through the exhaust port, any damage here and the saw will require a re build and possible new cylinder and or piston.
Have you any compression? If not, pour a few ounces of motoroil in the spark plug hole to place some oil on top of the piston and let it soak for a day or so. Fit an old spark plug and check compression. It should be good now. Turn the engine over a few times to blow the excess oil out and fit a new plug. After checking the petrol and oils is mixing OK and the carb is "wet", try starting again.
Make sure the gear box has fresh oil and any hydraulics have fresh fluid. Hope you get it going.
I would recommend a serious carburetor cleaning or even installing a new rebuild kit after the machine setting up for so long. The spark problem must be checked for either the (magneto to flywheel air gap) or the condition of the electrical points and condensor on it (if this older model has them)
check that fule is getting into the engine and you have a good clean spark plug with a good spark on it and the air filter is clean
try tipping a cap full of fult (2 stroke mix) into the carb throte right into the engine then try to start it up,,if it spluters into life and stops the carb jets are blocked up or no fule is getting to the card
