Ken, Had a similar story with my rally car. It is an L18 and has not been modified other than carbs (SU's), extractors and elec. dizzy. I found mine would run really crap until I revved the rings off it and then would be OK. I have been running Optimax for the 4-5 months and the thing is so much happier. Idles better and non pinging, hesitation, whatever. Part throttle response is good. The only problem was I had to replace fuel filter (twice) as the Optimax has a cleaning agent which removed all the crap from the fuel lines and tank. --- "Ken Abraham" <[EMAIL PROTECTED]> > wrote: > > > ><DIV><FONT size=2>List Members,</FONT></DIV> ><DIV><FONT size=2>I have discovered the reason for my rough running >L20.</FONT></DIV> ><DIV><FONT size=2>Lead Replacement Petrol.</FONT></DIV> ><DIV><FONT size=2>On part throttle openings when the vacuum advance is working >it runs poorly, but when you WOT it the vacuum advance ceases to advance >and the engine 'comes alive'.</FONT></DIV> ><DIV><FONT size=2>Strangely, it doesn't 'ping' it just misfires.</FONT></DIV> ><DIV><FONT size=2>Modified engines should probably not drink LRP even for >commuting.</FONT></DIV> ><DIV><FONT size=2>What are your experiences?</FONT></DIV> ><DIV><FONT size=2>Regards,</FONT></DIV> ><DIV><FONT size=2>Nick</FONT></DIV> ><DIV><FONT size=2> </FONT></DIV> > _____________________________________________________________ Get Your free Ozdat Email Account ---> http://www.ozdat.com --membersozdat------------------------------------------------------- OZDAT Mailing List Please Note:- Send (un)subscribe requests to [EMAIL PROTECTED] Send submissions to [EMAIL PROTECTED] No unauthorised redistribution of this email http://www.ozdat.com/ozdatonline/index.htm http://www.ozdat.com/ozdatonline/listindex.html http://www.mail-archive.com/[email protected]/ ---------------------------------------------------------------------
