    hi all, are there any LPG experts out here? particularly regarding non sequential systems fitted via carb to a dodge/ford/chevy V8 ?

    thanks
    John

    Hi John.

    Mine's a Tartarini.

    Just waiting for a brand new Edelbrock Carb and New Electronic distributor before I get mine set up.:thumb:

    I have noticed they are mainly Impco if converted in the States.Was yours converted Stateside Olley?

    Nearly bought an IMPCO complete lpg conversion, but this was a full conversion involving the removal of the carb and no bi-fuel switching.

    Good kit though.

    lpg+pic+2.jpg (image)

    is mine...

    seems a tiny gap for air to come through and mix with gas, when switched to LPG..

    also there is a (manifold) vacuum switch that seems to be wired backwards, this controls vac to mixer..

    supposed to be full vac to mixer on petrol, allowing the mixer plate to rise and open completely = full air into engine and then on LPG the vac should be cut off, allowing a much smaller amount of air in..

    getting my head around it :)

    maybe more to follow..

    Hi AD no it was converted by Logical near Northampton, got ripped off, didn't research it enough at the time, all fuel injection engines should be multipoint, but by fitting a gas carb he saved money. Still live and learn.:Angry:

    Hi John I believe that RPI that Alan mentions are at Horsford near Norwich. There is also another good firm in the area who converted my Hurricane a couple of years ago, they are JAYMIC at Cromer.

    dunno ;) its much harder trying to look into the carb while its fitted, very tough.. (I keep checking me butterflies are behaving):Rofl1:

    spoke to my lpg chap and he confirmed a question I had about manifold vacuum controlling airflow into the mixer... so should be able to sort that,..

    thanks for pics Ginge, yet again a different set up. :)
