yes, it all would be interesting to try, have a vehicle run on LPG, but i live here in northwest montana, and so it wouldn't be really practical.

another thing: as far as fuel economy goes.

now, right now, things are not as good as they can be on the car and the shocks need to be replaced (they are actually so shot that they are kinda frozen in one position and rarely move up or down unless under great movement, never at all for little bumps). also, there is a fairly 'large but not so big that it can't wait till spring' amount of rust on the car. little electronic and cosmetic stuff, but right now i'm working on mechanical, which is probably the most importaint thing.

i am running a weber DGV carb on a TWM intake (no idea of its origin, except i think the company is German) and an original exhaust manifold that has the intake half cut off, presumably with an oxy-acetylene torch. i adjusted the idle mixture screw to about two turns out and finally got the idle setting constant after adjusting a too-short throttle linkage. now the tranny (auto) doesn't shift as early as it used to, thus (i know it does for a fact) lowering my fuel economy tremendously because i've ran low on fuel several times when i've tried to make the thing go over 60 for any period of time. the car doesn't seem to like to have the engine 'screaming' like that, and neither do i. the head has recently been redone, about 3000 miles ago, as well as the carb rebuilt between 200 and 400 miles. the jets have not been changed at all. i think they are the biggest ones that came in the set, being a 065 and a 135 for the idle and the main, respectivly. i could be wrong on the main number. might be closer to 155 but i'm not wading through snow out to the glovebox to find out. i think the jet set is paired with the carb cause i got it and the manifold setup from my 142 which is now 'decommissioned' as well as the jet set which i got out of the other unused spare tire well. the wrapping was moldy so i assume it had been there a while, likly the age of the carb.i am assuming both, or i know the jet set at least, came from IPD. anyway, what can i do to improve fuel consumption as well as possibly prevent the engine from losing vacume so suddenly when i stomp on the gas, a condition which i was instructed on by Jeremy of IPD? (this loss of vacume causes the engine to bog down and some times pop out like its running lean when its actually running rich, it just doesn't have enough vacume to suck any gas into the cylenders)

thanks for your imput up to this point, btw everyone. i learn more every time i come on to the brickboard.
