Runs better at sea level

Considering how often you might use it, it may be better to pay á garage who could set it accurately using a gas analyser?

I had a flexi drive one. I find it hard to get a feel for how the screws were moving and after a couple of uses the flexi shaft broke away from the head. I sent it back and invested in a bevel gear drive unit.

The gear drive unit works much better and is worth the extra investment. The Motion Pro one looks very good and good value, I've got other tools from them and they've always impressed me with the design and quality. The slimmer angle drive head looks much more compact compared to mine. Might be time to upgrade

JD good point. Shops here seem to not like to deal with carbs; at least that has been my experience.

I got a speedo gear and a cable from a Sprint on ebay so back on the road.
