...an update on this old post of mine, in case anyone's interested: Turns out the box mounted on the firewall is supplying voltage to the solenoid in front of the vaporizer as follows: when the ignition key is turned, it opens the solenoid to allow for priming (first clicking sound). You could crank...

The idle mixture should be set by turning the idle mixture screw in or outwards for the maximum idle rpm Just noticed this and it reminded me of a question I've had for a while: Should the idle mixture screw be adjusted to the max idle rpm when the engine is cold or when it's warm - I find that the...

Hi Rob, I got my LPG setup from Torquegas in Australia - http://www.torquegas.com/ - not sure how far that is from where you are, but the guy there, Ron Flanigan, was very helpful. I have a Technocarb, open loop on a 400 smallblock - I also have the same flow going to both sides of the mixer, from a...

...Bear with us, there are a lot of lurkers on this forum who read but never post, and those are the ones we are trying to help, and since we never learn of their results, we have to try and catch them on the front end. Fwiw, here's one (lurker) ;-) I, too, am following this thread with interest. I...

fwiw, I got it all from TorqueGas in Australia Update: Figured out the black plastic box under the converter is the primer. It has a screw on it for what I think is for adjusting the mixture (lean/rich) for priming (i.e. how much fuel it uses for priming). It seems the rectangular box mounted on the...

Is the primer is what you can see directly mounted to the left of the converter? (2nd picture further above) If so, it says "TYPE 07-LPG-MAX W.P.3 MPa AGA 5135" (see writing on the brass part in 2nd picture above). The leaflet that came with it says it's an "Airod Series 07 Direct mount Gas Solenoid...

PS: Just out of curiosity - is the vaporizer appropriate for the mixer & engine; or to rephrase: would it be worthwhile having 2 vaporizers? (the mixer is fed by 2 hoses, with a Y coming from the one mixer, as you can see in the engine bay picture below).

It's been over 2 months now and I have never had the issue of the primer not priming properly again (as described earlier) so far, but I have finally gotten around to taking some pictures. My car is a '73 Chevy Impala wagon, 400 sb with Edelbrock Performer heads & intake manifold and Technocarb mixe...

Thanks, sorry I probably didn't explain right. Cranking/starting is totally fine. The "clack - faint sucking noise for 2-3 seconds - another clack" is when I turn the key to the ACC position (I think that's what it's called), i.e. before I crank it. When I turn the key to the last position (i.e. sta...

Hi all, after years of completely trouble-free motoring, lately when I start, it sometimes doesn't behave as usual. Here's what's happening normally: When I turn the key, there's a "clack" noise (sounds like a relay), then you can hear a faint sucking noise for about 2-3 seconds and then another "cl...

[*][webbew]If you are trying to estimate gasoline economy on an energy basis compared to propane, you would divide by 0.726 rather than multiply. That is, your 16-17mpg (US) average economy on propane would get more like 22.0-23.4 mpg on gasoline. I would expect a station wagon with a 400 CID engine...

No, unfortunately I don't know the revs - I do know that when gently accelerating, it shifts into 4th around 75 kph. One day I'll get around to going to a dyno and seeing what's what, but right now, I'm preparing for a bit of a visual makeover - a few minor rust spot repairs and a complete repaint.
