Hi edmeyers70

run engine to tdc compression stroke with plug out, and then set the piston 1/4 " past tdc on power stroke , then set the valve clearance at this piston position to ( off the top of my head about 0.003" inlet and 0.005" ex )

think these engines are briggs ohv single vertical


if you get model and type codes from your engine plate eg 351777-0112-e1

write yours down

here is web site

www.briggsandstratton.com

also www.partstree,com
go to briggs engine brand , select your engine series and then type code
parts diagrams will open up

Check your valve adjustment first as these uses a decompressor that on the camshaft itself.

Now while checking the valve clearances as you go past TDC of the compression stroke there should a little bump on the intake valve when the decompressor is working. If this bump is not there and the valves are set correctly then the decompressor has failed and requires the cam to be replaced.

Need valve clearance on Briggs eng. Mod. 407777


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.

I need to know the over head vave setting for the intake and exhaust on a 17.5hp Briggs & Stratton vertical shaft, single stroke lawn mower.

set piston to tdc compression stroke then run it down the bore a 1/4 inch

set the tappetts to inlet the bottom valve ( alloy push rod ) to a tightish 0.004" and set the
ex valve the top one ( steel push rod ) to 0.005"

setting at 1/4 pst tdc eliminates decompressor from upsetting valve clearance seting

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.
