You will have to hold the flywheel for removing the clutch. It may require removing the blower housing.
I use an impact wrench which loosens the bolt w/o holding the flywheel.
It's 99% a regular bolt (turn ccw to remove) since left hand threads cost more to buy the bolt and tap the hole and small engine stuff is made as cheaply as possible.

Not likely carb because both cylinders would act the same; not likely coil because both cylinders fire together, however could be wire/boot from coil, plug or low compression/valve adjustment. Premium fuel works miracles on small engines; try a couple of gallons, it will increase horsepower. Check compression and compare to good cylinder, if close, suspect plug or boot. If compression low, hope that valve adjustment will normalize. Good Luck

turn the crank shaft and watch the relationship between the piston position and the cam followers. As the piston nears top dead centre you will see the exhaust cam follower start to move down and the inlet cam follower start to rise up. This will create a rocking motion of the cam followers at top dead centre. This is known as valve overlap assemble the motor in this position. Ensure the valve clearance is backed right off Turn the crank shaft one full revolution and you now have the compression stroke . This places the piston again on TDC and it is at this position you adjust the valve clearance. Check that clearance for the tappets as most engines run .010" and .012"tappet clearance. If the head is fitted last place the push rods in the cam followers if you cannot see the cam followers and it does the same job. When the top of the push rods reach the overlap situation it is just an extension of the cam followers.

this allmost allwways means a bad head gasket if this happens , and most head gasket failures are from overheated blocks meaning a warped head face
but on rare occasions it could allso be a bad valve stem seal
