Yes CO my chemistry was never up to much.

I'll try it richer and see what I get.

enlightened us thusly:

At idle I was getting about 1 to 1.2 % co2. Reducing to 0.5-0.6 ish when
running
the engine at 2-3000. rpm.

I'm a bit uncertain here due to the fact I've had conflicting quotes on
what
to tune the co2 to for LPG.

What C02 do you suggest?

I assume you mean CO. 0.5-0.6 shouldn't be far out. You might want it a
touch richer (i.e. higher CO figure) at 3000, but it shouldn't be far off.
Try it a tad richer and see what happens.

if it's a bit rich, you get the thing where it fires initially and then
conks again - if you have a switch with an "off" position, you can try
turning it off while cranking, and see if it fires again. They mostly
seem
to need a bit more throttle and a bit more cranking than a petrol carb.
