I would try and replacing the spark plug. The fitted plug is an NGK BM6. I wonder if this is the correct type but can't find the type in the B&S Part List. Which is the correct plug for the motor 220707 code 120411 please?

Thank you very much

I fitted a plug NGK B4-LM (THE "2" was not available). The behaviour is the same, if a little less cahotic. Starts well, good at low RPM, not possible increasing the speed or loading.
What else can I do/test?
Thanks

Sandro,

You need your own posting instead of hi-jacking someone else'.

It creates confusion when following these posts.

I agree. I posted my problem in this thread regarding same object thinking that shearing experience could be useful. Moreover in other forums it happened to me to be told: "Why do you open a new thread while already there is another on the same subject?. Please post in that one".
Anyway, an admin could move my posts from this thread to a new one, mine only. I would carry on on that one.
