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,

Hi and welcome to FixYa I am Kelly,

First off parts source:
http://www.partstree.com/parts/?lc=briggs_and_stratton&mn=406777-0128-E1&dn=29860008H

Next engine service manual:
http://www.mymowerparts.com/pdf/Briggs_&_Stratton_Service_and_Repair_Manuals_Spec_Charts/273521%20Twin%20Cylinder%20OHV%20BRIGGS%20&%20STRATTON.pdf
Governor and controls is in section 4 page 34 (begin) though page 40 (end)

This should be what you need to correct the problem. Just make sure that one of the pieces of the carb had not fallen off of the throtle control.. (butterfly x 2) They are mounted with screws onto the throttle shaft and if one comes off.... all the adjustments on the governor have to be un-done....

Thanks for choosing FixYa,
Kelly
