Stihl 661 Magnum Flooding Issues

[Mad3400]

Any updates on what the cause was?
I got the same problem with a new 661. First tank and a half it ran great, now it won't start and is completely flooded.

Were you trying to start it from cold?

Is it the Standard Carb or M-Tronic version?

Yes, cold start with M-tronic.
Tried new fuel mixes from different jerrycans to make sure it's not a fuel related issue, took the spark plug and filter off overnight to make sure it dries well, but same issue this morning .

Are you using the Decompression Button?
