I need the valve lash clearance specs

0.15mm +-.02 intake. (.006 in)
0.20mm +-.02 exhaust (.008 in)

for specifics, you really need the maker of the engine and not the supplier of the generator. They tend to be Briggs and Stratton or Honda. There are some videos that may help, but Engine make and model will get you the manual for the power plant.

If this is your non-inverter model, the 'maintenance' section is lacking in any real information. The engine 'Service Manual' is what you need, but for that you need the make and model. Briggs and Stratton have a page of valve settings

No exact model given so we take best guess.

Hi!
You need to adjust your valve lash clearances to: Intake: 0.015" (0.381mm) Exhaust: 0.015-0.020" (0.4-0.5mm) (Try smallest setting first.

Edited for clarity and moved from Cars to Generators.

Valve clearance goes by the engine, not by the generator maker. They are usually Briggs and Stratton, Honda or Kawasaki.

Hi!

You need to adjust your valve lash clearances to:
Intake: 0.015" (0.381mm)
Exhaust: 0.015-0.020" (0.4-0.5mm) (Try smallest setting first. If still not running right, change clearance to 0.020".)

if you cannot get the specs from on line or from a service agent , generally the following apply:-
water cooled engines
inlet hot .010"--exhaust hot .012"
for air cooled engines inlet hot .012"-- exhaust hot .014"

Use the name plate information on the engine to identify the make and model of the engine. You shuld then be able to look up the engine specs on-line.

There is a specific procedure for setting valve clearance . I highly recommend getting a repair manual for the correct specs & procedure. The engine must be at TDC with the #1 cylinder on the compression stroke , that will allow you to adjust ONLY certain valves , then you have to turn the engine one turn to TDC again only now #1 will be on the exhaust stroke & the rest of the valves can be adjusted . it's important that you know the difference between the two !
