Timing on all Briggs & Stratton small engines is set at the factory and non-adjustable. It is determined by the placement of the armature (coil) and position of flywheel on crankshaft. Unless the crankshaft is bent or the flywheel key is sheared (both are possible after an impact or sudden stoppage), timing is perfect. Rough running is likely an intake or mechanical problem.
10 thou
How many horse power is 342cc
It can have anywhere from say 10 to 20 hp but is around 10 stock
Try 32 thousands, to start, depends on how much compression the engine has at this point.
There is not such conversion of displacement to HP. You have what is basically a 17 cu. in engine and that would seem to be and 8 to 10 HP engine in an OHV configuration.
Most Briggs and Stratton (B&S) engines of that size can have the spark plug gapped to 0.030" What I truly recommend is that you visit the Briggs and Stratton web site and download the engine owner's manual. You will need the Model Number, Type Number and maybe the Date Code. This information will be used to obtain the appropriate Owner's Manual. You can also obtain the IPL (Illustrated Parts List) for your particular engine. The web site is www.briggsandstratton.com - and you can take a look around for the manuals.
During the summer a 30 weight oil is all that is recommended. During winter operation a 10W-30 oil is reccomended.

it may not have one. If it does it will be located on the fuel line between the fuel tank and the carburetor.
Check wires for insulation cracks. Buy an electronic (solid state) ignition conversion from Stens for $10 and install (instructions come w/kit). This will bypass old and unreliable condensor and point ignition system.
The gap is 0.30. It is on the owners manual ? 10-28-08 That sounds like a spark plug gap. Other specs: Armature air gap: .008-.012 Valve/tappet: .004-.006 intake AND exhaust, cold.
