Thread: Mounting LPG converter

Currently it is mounted in the vertical plane and upright but I'm moving things around a bit.

Thanks.

And what brand of lpg converter is it? Impco type converters don't mind being laid down, complex ones are best mounted vertically with the plane of the diaphragm parallel to the engine. Some units are fussier than others. If there is a drain plug that is a sign that it should be mounted so it's at the bottom.
The lock-off and filter unit can be fitted upright or sideways but preferably not upside down (coil at the bottom).

What convertor ? not that it matters !! They should be mounted Vertically , and facing front to Back , with the Vapor hose as high as possible . If your using a positive convertor . make sure you can acess the Idle mixture and sensitivity screws .

Bee Utey , even negative convertors(Impco . Nolfs , OHG , and B2's ) will still suffer the problems of Horizontal mounting that a positive convertor does . Seen many negative convertors stuff up , especially B2's when used with those crappy GRA throttle bodies .

For sure, but it seems to be quite common to mount Impco's flat. I wouldn't do it myself but they at least are tolerant of this as the idle is controlled at the mixer. I don't actually like Impco and its clones but that's another matter.

It is a Landi Converter. Not the Landi Renzo.

I have been googling and it seems that it should be mounted vertically. But also with the diaphragm lengthways in order for it to not be affected by acceleration and braking.
That is how it was mounted before I pulled it out too.

That certainly narrows the options!

I'll have a look for a drain.

Was always under the impression that B2's should be mounted horizontal, when in big HP installations, what's wrong with gas research carbs? I used one on a blown 3.9 rover, worked a treat, far better than any other mixer I've used......once correctly tuned

If they are vertical in the GRA the mixtures will wander a bit.
In a "conventional" setup it is usually preferable for the converter to be vertical and in the direction of travel.

Just for gas research stuff, learn something new every day

The model appears to be 'TIPO LSE 98'.

I've tried to get info on it before with no luck.

Just looked and there is a drain hole on the bottom.
