Yamaha G16 Quit Running

[cwinkslinger]

My Yamaha G16 has run fine forever..then it quit running and won't start. I have good spark, fuel enough to wet the plug and sufficient compression. Won't hit a lick....HELLLP!!!

did ya try a new plug, somethings they'll spark when checked but won't fire in the cylinder.

Is there too much gas?
Are you using the choke each time you try? If you are, try with out.
Or you could go to my favorite next step. Let it sit a while give it a shot of starting fluid and see if you can get it started.

thanks guys, but the new plug didn't help nor did the starting fluid...a brief rumble but not to actually run..what controlls the timing?

 

[COPB]

Most would say "good compression." You have spark and gas. Timing is seldom a problem. What do you say, Nubs?

 

[COPB]

Could be your valves need to be set.

 

[Nubs]

Well a known compression number will give you a good idea of whats goin' on. anything under a 120 lbs and there is a problem somewhere, checking the valve clearance should be done once a yr on older units

Sure hate to say this...but I figured it out...broken cable to the governor. Finally noticed that the carb lever wasn't moving...DUH!!! Thanks for the suggestions though and I do appreciate it.
