Honda EM3500S generator won't start

[dkell00]

My generator won't start so I've done the following which has not helped. I replaced the plug, changed the oil making sure it's full, drained and replaced the fuel including draining the carb bow. I pulled plug and made sure it has spark and then sprayed some starter fluid, then tired gas but still wont start. Seemed to fire a few times but did not start. put finger over plug hole and seems to have compression. Could spark be too weak or not sparking under compression. any ideas

check the valve clearance.

intake clearance is 0.006 inches

exhaust clearance is 0.008 inches

if you use metric gages,

it is .15mm intake and .20mm exhaust.

Thanks for your response as you put me on the right track. When I removed the valve cover I discovered one of the bolts holding the rocker arm was broken so I will order a new one from Honda. Can you please tell me exactly how to adjust the valves once I replace the rocker arm.
