Re: i need to remove the flywheel on a 288 husqvarna...
You need a rope with nods on it ,put it on the sparkplug gauge to block the piston in the cilinder,after that try to unlock the clutsch and the flyweel.Then disassembly the engine and change the seals.

the coil is on the flywheel side of unit. remove the recoil cover and you will see the flywheel and coil. your have to remove the ground wire from shut off switch and two bolts holding coil in place. when installing new coil you need to leave a 10 thousand air gap between the coil leg and the flywheel magnet for proper operation
If you have good fuel and a good spark it may be a mechanical issue, remove the muffler and check the condition of the piston face through the open exhaust port, any signs of damage or scuffing and it will need to come aprt to assess the damage, if all looks good it may be a crank seal leaking, the 36 was prone to blowing the seal behind the flywheel, also check the flywheel key in the flywheel has not sheared knocking the ignition timing out.
This souds much like an air leak, if the engine is pulling air somewhere other than the carb it will lean the mixture and increase the idle speed, you are looking for a leaking gasget or crankshaft seal, this is no so easy without proper tools to do a pressure test, you will have to start changing parts in the hope you will find the cause, start with the impulse pipe on the carb mounting block, and the rubber induction hose, if not there remove the clutch and sprocket, behind the oil pump will be the crank seal, it may have come out of the bearing i have seen this happen, to get to the other crank seal you will need to remove the flywheel.
Could be a massive air leak, possibly the crank seal has fallen out, or the cylinder base gasket has blown out, remove the flywheel and check the crank seal behind, remove the clutch, sprocket and oil pump and inspect the crank seal on this side,if they have fallen out, or are very wet, replace them, there are kits available to blank off the inlet and exhaust so as to put a pressure into the crankcase to quickly show where the leak is.
The 41 was quite prone to blowing the crank seal on the flywheel side, remove the flywheel and check, at the same time check the flywheel key has not sheared, behind the carb fixing plate is a rubber induction tube, make sure this has not split, als check the impulse seal underneath the induction tube.
If there is a good spark and there is good fuel at the plug the only reason it wont fire or do somthing is if the ignition timing is out, this can happen if the alloy flywheel key has sheard, remove the flywheel and check, unfortunatly if the key has gone it is a new flywheel.
