Paolo,

Sorry bout that dude, my opinion is offensive.
Overkill indeed SGi to carb but there will always be some out of many for personal reasons.

regarding this:
[quote=leatherman;1103813]Any reaction from installers who are active in this forum but are not in the list?

Not to put anyone on the spot. Just want to know why.

Are there unreasonable requirements from govt agencies? Issues with product/service standards? etc...

I'm not an installer but backreading the thread you'll notice that one of the accredited or certified gives a crappy aftersales service, probably means their tank may be strong but the system sucks.

However, it would be nice for the leading contenders here that they'd get certified too, it would cost them money for such.
