Tuning, you may have to retard the ignition and increase the gas flow.
It will use more gas, but it is cheaper :-)

Its normal to loose approx 10% power with duel fuel conversions, if you
have lost more than 10% I suspect it running too lean.
Take it back to whoever did the conversion and get it checked asap.

Don't do that :)

Retarding the timing will only make it worse unless it's got way too much
advance now, and you'd notice that on petrol if it did.

Tuning gas systems is like tuning anything else in that there's different
types of systems than each have their own peculiarities and need special
attention to suit. There shouldn't be anything other than a mildy noticable
power difference between gas & petrol on a dual fuel system, but if there is
then you need to get it back to the gas fitter and have them tune it
*properly*.

That's what you paid them for.
