Try pulling out the choke a little, if it stops backfiring the mixture is too lean, check the intake
pipes at the cyl head and also the plastic runners to the carb for leaks.

possibly a commpression test might throw a little more light on the situation ,that will eliminate alot of speculation, and make it easier

these are common for doing this ,if you dont want to pull it down and hone the cyl. then i would use a heavier oil say 20w/50and that will probabley solve your problem

SOURCE: how do set valve lash
Turn the motor until the piston is at TDC. Look through the spark plug hole. piston to top of the cylinder. Then set them like you would any OHC rocker arm. BE very careful with the exhaust valve adjustment. There is like a mini disc on top of the valve stem spring keeper. If you get it too loose on a vertical engine it can drop out and it will take you forever to find the little bugger!
Below is only a recommendation....
I don't know how many hours that are on this engine your working on but... I would recommend you hand lap the valves with grinding compound if you know it has high engine hours. It will make it easier to start and have more power. The exhaust valves on these engines get very noteable black gunk buildup in the seat to the point you can not see the "valve to seat" mating ring on the valve head. The heads are not hard to remove... (One at a time) just time consuming. It can be a chore getting the valve push rods aligned with the engine horizontal. Most of the time and I know good Mechs don't like to hear this.. you can reuse the cyl head gasket on this model due to the design. Once in a while they break not very often.
The valve springs have keyhole locks on the keeper.
Thanks for using FixYa,

The crankshaft should have a marked "tooth" either with a "dot" or a "-"mark, the camshaft will also have a corresponding dot or dash. By rotating the crankshaft, align the marks on the crankshaft & the camshaft so that they are directly opposite each other. Drop the camshaft into place and the engine is now "timed"--if the marks are not exactly opposite one another, lift the camshaft (just enough to disengage the gear teeth) and try again, being "one tooth" out can make a huge difference--so take your time and make sure the "marks" are directly opposite each other.

Set No. 1 cylinder at 1/4" past TDC (Top Dead Center) on compression stroke. Gap both valves at .005". Gap is set with the engine being cold. Do the same for the other cylinder. Be sure to lock the adjusters back in place.
