I'd love to be able to check HC but I have no idea about these machines, I would have no clue what I was buying, how do you even know if this machine works and is acurate?

As far as I Iknow if you turn up for MOT on LPG it doesn't have to be tested

Hi,

[quote="itchyfeet"]personally I put the vehicle in on petrol.
because it;s easy to get a carb to pass much harder to get the lpg right and mine does not pass on.

This is not a criticism. If it would not pass on lpg then does it not indicate that it is 'out of tune' and therefore costing money and possibly causing damage. Maybe I'm wrong.
I put mine in on lpg 'cos that is what I run on and the MoT result tells me it is set right. It is the only indication I have.
When the CO figure was too high a couple of years back the van was running fine so I assumed all was ok.
Running, wrongly, on petrol I can pick up on by looking at the plugs etc

Machines like the Gunson are never going to be as good as the full size professional ones but I can't afford a professional one, or have the space, so a Gunson, or similar, will have to do. There have been quite a few 'quotes' on the web that say the owners Gunson readings are the same as the MoT ones.

Some of my MoT certs. give HCC readings others do not.
