Can not start suzuki df6 2014

[kuralex]

Hi guys, I have the Suzuki df6 2014 outboard motor. Last time When I was on water, the water stops coming out and engine shut down. Seems like the motor was overheating. Before shut down it was working less than 1 minute. Now I can't start motor. I checked the spark. I replaced spark plug, ignition unit, cleaned carburetor. No luck. Could you advice what to check next?

Thanks,
Alex

Hi
if it turns over by hand ok, I would be doing a compression test before anything else. Good luck

Yes, Thanks. I was thinking about compression test as well. But when I am pulling, I feel good tension. The motor is trying to start, but seems like the problem is earlier ignition because when I pull recoil starter It snaps back. Weird. As I know this motor does not have adjustment ignition.

Ok. Maybe still worth a compression test. The tension might be bad news and perhaps caused by damage internally. A damaged piston and rings scraping on the cylinder would cause tension. Maybe a bit drastic, but be good just to rule out the worst.

Seems like I found the problem. The valve push rod goes out from guide. As a result, the exhaust valve was closed constantly and motor could not start. From my perspective it’s design flaw of Suzuki.

Hi guys, Maybe you have manual for valve clearance adjustment. Thanks, Alex

You say the engine overheated and seized and it's a DESIGN flaw?!!

Valve Lash (TDC Compression Stroke):

IN: 0.13 - 0.17 mm (0.005 - 0.007 in.)
EX: 0.13 - 0.17 mm (0.005 - 0.007 in.)
