Hi all,
Since last year I've noticed stuttering on the low revs - up to 3/4 000 rpm. When i keep the revs at around 2,500 rpm the engine sounds nearly like an old two stroke.
I've searched for similar threads on this forum, followed the advice there and I've:
- replaced plug caps
- checked spark plugs
- balanced carbs (Autumn)
- I've added some carb cleaner to the fuel (Profi Fuel Max) - didn't seem to help much
I think that there are two possibilities left - either the HT leads (and coils) need replacing or the jets are clogged.
Do you know how can I check whether the HT leads are faulty, and what should I use for cleaning carbs (once I open them up).
Or maybe you have some other ideas ?
Thanks
