Well, the Clacton dealer agreed with Tripp Batts that it's running fine. However they said it's a 4 stroke running on 2 stroke mix, whilst TB said it's a 2 stroke with valves. No difference there then
A mechanic friend of mine says it's running s###e, so not sure what to do now.

Thanks Tomtop.
I'm working in clacton tomorrow, there is a Stihl dealer there, I'll get their opinion on how it's running. They might think it's typical for the model.

Hum, it seems that Tripp Batts are saying its fine by running it up with no attachment fixed, whilst I'm running it with the strimmer head. Surely the engine needs a load on it to say its fine?

Would I be right in assuming that if max revs are not achieved before WOT it needs leaning out? Conversely, if max revs come in well before WOT it needs to be richer?

Thanks BBB. Ill pass that on to Tripp Batts. I was surprised at the exhaust note produced by the machine. As you say, a lot different to my other 2 strokes.

I put the premix Ultra in, but the shop was happy to sell the red stuff for it. When these things are running right do they rev freely? Mine seems to choke above half throttle. I would say it was running rich, but there is no sign of smoke, and the dealer says its fine. Yeah right!
-
Tomtop, does yours rev for the full range of the throttle?

Forgot to say that I have been uber careful running it in but it still runs crap above half throttle.

Hi all,
Just got a brand new KM130 from a Suffolk Stihl dealer. I've used the premixed fuel recommended for the machine and I'm not impressed. It's ok up to half throttle but above that there is no appreciable increase in revs up to full throttle, it's destinctly unhappy and there is an increase in the machines vibration level. I took it back for the dealer for them to have a look at and they say it's running fine. Really? Is this true? What would be the point in having a throttle that is only good for 50% of its travel? I would really appreciate your thoughts.

Hi Tomtop, I live on the Suffolk/Essex border. I'd be more than happy to pop up to Norfolk to determine if I'm right or wrong. After around an hours use I can't feel my hands, unlike my ancient Dynamac (yeh, I know), which even after 12 years use is silky smooth in comparison.
