Thanking you for the photos .... It clears up so many questions
All your parts "look's the goods" ... I could make some comments on some of the choices, But will leave that for another time
Mathew ... So what you are saying is ...
ON GAS ... the car drives like a dream and has plenty of power
..... BUT....
ON PETROL .... it runs like a Dog
Right .... Now onto this business about the Vacuum advance ....
Your saying that "Nothing happens when you suck on the Vacuum advance hose"
The below will help you get the idea of what is suppose to happen, when the vacuum unit works properly .....
Now take the Dizzy cap off
In this picture you can see the "METAL base plate" under the black cover (under the rotor)
(Under the rotor ... is a 8 sided star cog on the shaft ... then under the cog is THE metal base plate)
DO NOT DISMANTLE the dizzy ... you should be able to "just" see a "bit of" the plate looking through that gap ... as per the photo

.... Suck on the vacuum hose and watch the Dizzy base plate move .... YOU SHOULD BE ABLE TO SEE IT MOVE
You should feel the vacuum on your tongue and it should hold vacuum .... if you release it Quickly and allow air in, you should hear a clunk, as the metal dizzy plate is sprung back into position
If all you can do is suck & suck ... and all you get is air ..... then it is CUPUT
So, in short ... something is happening... and it is either
1: Just sucks air (Cuput vacuum advance unit)
2: Vacuum advance moves that metal plate, as you suck out the air (Works great)
3: I sucked out the air, till I could not get no more, but the plate doesn't move at all (Jambed)
Now for your spark plugs ....
Your using .... NGK BPR6ES ..... Which I believe is suited for Gas and is correct
.... But like most items .... If you have given them a Flooding of petrol, then these plugs can foul up & break down .... "Replace them" is the only fix for that
Now for your TPS ... which is a black button screwed to the "front side" of the butterfly, and has a cable of wires going to a plug ... the wires are coloured / Red / Green & black ..... If your car Idles fine .... gas or petrol ... then theres a good chance that all is well .... However, A faulty TPS will give you "ECU farts" .... You have to test it with a Multi meter to find this out ... More on that later
Now for the big ticket Item ..... If you could clarify ....
You ran the car out of Petrol .... Drove it for a while .... Then Immediately after you filled it up with petrol, it started Farting all the Time, ... and it really only "Farts about" on Petrol ever since
Is this Correct???
