Tb42 duel fuel carby issues

[Bigcol]

I've had 4 cars that were Gas powered
MK with 2.8L petrol gas
AUII dedicated Gas
GQ 4.2L carby petrol gas
GU 4.2L Diesel Gas

I do like it , but not the cost to get it fitted
lucky, all my cars were already fitted before I brought them

when I brought the MK - Gas was $0.21 per Liter
used to cost $22.00 to fill the 80L tank, and used to do about 400Kms in it per week

oooohhhh
nice and red................

now, you see this here Valve -
Attachment 60343
this controls the amount of Gas going into your Carby
for some strange reason, that I could never work out, whenever the bonnet is open, people like to play with it
twist it in, or out

and then the car runs crappy

when you get it tuned, good idea to put a nice little mark on it and the pipe
so if anyone DOES play with it, at least you can get it back again

Yeah, I bought one of those power valves to fit in. Then realized it's too small for the LPG hose I have.
It's still sitting in the car. I can't use that power valve without any mods to it, and can't find a power valve to suit the
the Impco 300A mixer hose diameter.
Can you guys point me to the right direction where to find a one?

with that "flash lube" bottle near the fire wall

sewing machine oil is just as good, and cheaper

Hey BigCol,
How do you get "flash lube" or sewing machine oil to mix with LPG?

its setup to "dribble" into the intake
mine was on a fitting drilled and tapped into the manifold
I think it was
1 drop per 55 seconds
or something like that, cannot remember off hand

Yeah, but what is the mechanism you use for that timing?
Where do you get it from?
Thanx

works on the Vacuum from the inlet manifold

As well as an upper cylinder
lubricant, I thought the
flash lube also had a lead
replacement that was first
designed to coat the
the valves in pre-unleaded
engines. I suppose it
isn't as crucial in an
unleaded engine though
as the valves are already
hardened.

Hi Dom,

I suspect the IMPCO 300a has a power valve built in see item 3

If you are using a ring mixer - then you need a power valve
