Bill,



You can download the ISSUU document from this URL.  If the link gets

corrupted do a keyword search for VEBUKA.com and paste the URL for the ISSUU

document into the Vebuka processor.



http://vebuka.com/download.php?documentId=170617143810-565a4e2359816bdffb6bba1f445031cc&count=392&title=undefined&ck=f



Save as PDF.  I'm not sure if you need PDF Pro to do this.  I have it and

was able to download/save the file easily.  The resulting document ended up

having every even page blank so I just reprinted the odd-only pages to Adobe

Acrobat to get rid of the blank pages.  Later versions of Acrobat Pro (I

have X) let you delete blank pages from within Inflight.



It's a 100+MB pdf file so email is not an option.  Time permitting I could

post it to my FTP site and send a download link.

I would rather start from 10 BTDC than from TDC :-)

An interesting thought but the vacuum advance plays some role too right?



Hmmmmmmmm!

Here is my thought about vacuum retard on the distributor.  I wouldn't mind

hearing from others to concur or tell me where my thought process isn't

correct.  The vacuum port from the Zenith Stromberg carburetor that feeds the

vacuum retard gives vacuum pressure at idle.  Then I think (tell me if I am

wrong) the vacuum goes away as soon as the throttle is open even a little.  So

as soon as you step on the throttle you get an immediate advance.

(de-retarded, un-retarded)  With the centrifugal advance weights in the

distributor, you don't get advance till the engine RPM increases.  So the

vacuum retard actually gives a quicker advance into the power position for the

spark when stepping on the gas pedal than the centrifugal weights alone.

If this came on rather suddenly I suspect you may have suffered a diaphragm or O-ring failure in the FASD.  A quick way to check it is to plug the air intake.  There is a small port in the air cleaner that provides air to the FASD (it gets the fuel from one of the carburetors).  I have experienced this in a local club member's car which was running overly rich.  I plugged the port and it smoothed right out.  This is a quick, easy test to narrow down the search for the problem.

Hello again triumph enthusiasts!  Working on the mixture issue and I was

wondering if there is a trick to it.  i have turned both carbs left and

right but not sure what I am doing.  Things are sounding better but not to

where it was prior.  So any tricks to the trade or does the back carb and

the front carb differ in some way?  If there is a method please advise.

thanks

Bruce

Third question at this time is ...  does this system fire the injectors with

12 volts?  many systems use a base voltage of 5 and 12  gives me a little

concern?



 Well, there's a resistor pack in the FI harness (attached to the firewall) between the ECU and the injectors.  I don't know the values but that probably indicates that the injectors do not see 12 volts.

No oil pressure switch on the injected cars?





 



 No, its function is performed by the switch in the air flow meter, which cuts power to the fuel pump when the engine stops running and the afm flap closes.

Well, there is an oil pressure switch, but only for the idiot light.  1

wire.
