It didn’t like it. It inhibited the flow so, say, whilst booting the car up a steep hill it would stutter and virtually stop. I couldn’t believe it at first, new element and all, but the car ran fine after I removed it. (Never did really work that one out…..the Jag probably had a very similar SU so why was it fitted there?)<o:p></o:p></p><p class=MsoNormal><o:p> </o:p></p><p class=MsoNormal>Another time, I had running problems, similar to the ones which Brian describes, which fooled me for quite a while. The car was up on a ramp for it’s annual MOT when I noticed that I’d managed to nearly squash my fuel line flat. The carbs could fill up at low revs so the car could perform for a little while, but then demand would outstrip supply…….<o:p></o:p></p><p class=MsoNormal>(But no puddle of fuel.) (MOT…..annual, legally required test of car’s roadworthiness. Recently dropped for cars over a certain age. So, no more MOT for the 3000. Strange for a Government to cut back on rules and regulations. And I quite liked have a second opinion.)<o:p></o:p></p><p class=MsoNormal><o:p> </o:p></p><p class=MsoNormal>Another general point….I’ve just been replacing fuel pump points. I took the pump body apart, just to check, and there was zero crud in there. Likewise, last time I checked, none in the carbs. I put that down to having an aluminium tank. Of course, there may be a massive build up of crap in the tank’s filter which will defeat me when I get too complacent….<o:p></o:p></p><p class=MsoNormal>Simon<o:p></o:p></p><p class=MsoNormal><o:p> </o:p></p><div><div style='border:none;border-top:solid #E1E1E1 1.0pt;padding:3.0pt 0cm 0cm 0cm'><p class=MsoNormal><b><span lang=EN-US style='mso-fareast-language:EN-GB'>From:</span></b><span lang=EN-US style='mso-fareast-language:EN-GB'> Healeys <healeys-bounces@autox.team.net> <b>On Behalf Of </b>Patrick & Caroline Quinn<br><b>Sent:</b> 30 May 2020 00:06<br><b>To:</b> 'Brian Drab' <bgdrab@redzone.ca>; healeys@autox.team.net<br><b>Subject:</b> Re: [Healeys] Running Problem and assistance from the list<o:p></o:p></span></p></div></div><p class=MsoNormal><o:p> </o:p></p><p class=MsoNormal><span lang=EN-AU style='font-family:"Times New Roman",serif'>Hello Brian<o:p></o:p></span></p><p class=MsoNormal><span lang=EN-AU style='font-family:"Times New Roman",serif'><o:p> </o:p></span></p><p class=MsoNormal><span lang=EN-AU style='font-family:"Times New Roman",serif'>Some years back the BN3 started to run poorly, not inconsistent to the symptoms you have described.<o:p></o:p></span></p><p class=MsoNormal><span lang=EN-AU style='font-family:"Times New Roman",serif'><o:p> </o:p></span></p><p class=MsoNormal><span lang=EN-AU style='font-family:"Times New Roman",serif'>After much trial and error I was getting nowhere. <o:p></o:p></span></p><p class=MsoNormal><span lang=EN-AU style='font-family:"Times New Roman",serif'><o:p> </o:p></span></p><p class=MsoNormal><span lang=EN-AU style='font-family:"Times New Roman",serif'>It then occurred to me to go back to how it was when the car left the DHMC, and I removed the inline fuel filter.

I did not blow trough the pumps. Next time I’ll remember to remove the gas cap though. It sounded like I could have blown up the gas tank (I didn’t). I had checked the needles on the vacuum pistons and they were solid in them. The only thing I have not done yet is to blow out the passages between float ball and the carb body. The quantity of fuel coming out of the line at the carbs when the ignition was turned on was quite significant. There was no air nor was there any debris in the fuel .<o:p></o:p></span></p><p class=MsoNormal><span lang=EN-CA>I have repaired cars that had identical running problems and in my mind it was a fuel starvation or delivery problem.

There has to be a solution, all I have to do is find it!<o:p></o:p></span></p><p class=MsoNormal><span lang=EN-CA>Thanks all.<o:p></o:p></span></p><p class=MsoNormal><span lang=EN-CA>Brian Drab<o:p></o:p></span></p><p class=MsoNormal><span lang=EN-CA><o:p> </o:p></span></p><div id=DAB4FAD8-2DD7-40BB-A1B8-4E2AA1F9FDF2><p class=MsoNormal><span lang=EN-AU style='mso-fareast-language:EN-GB'><o:p> </o:p></span></p><table class=MsoNormalTable border=1 cellspacing=3 cellpadding=0 style='border:none;border-top:solid #D3D4DE 1.0pt'><tr><td width=55 style='width:41.25pt;border:none;padding:9.75pt .75pt .75pt .75pt'><p class=MsoNormal><a href="https://www.avast.com/sig-email?utm_medium=email&utm_source=link&utm_campaign=sig-email&utm_content=emailclient" target="_blank"><span style='mso-fareast-language:EN-GB;text-decoration:none'><img border=0 width=46 height=29 style='width:.4791in;height:.3055in' id="_x0000_i1025" src="https://ipmcdn.avast.com/images/icons/icon-envelope-tick-round-orange-animated-no-repeat-v1.gif"></span></a><span style='mso-fareast-language:EN-GB'><o:p></o:p></span></p></td><td width=470 style='width:352.5pt;border:none;padding:9.0pt .75pt .75pt .75pt'><p class=MsoNormal style='line-height:13.5pt'><span style='font-size:10.0pt;font-family:"Arial",sans-serif;color:#41424E;mso-fareast-language:EN-GB'>Virus-free. <a href="https://www.avast.com/sig-email?utm_medium=email&utm_source=link&utm_campaign=sig-email&utm_content=emailclient" target="_blank"><span style='color:#4453EA'>www.avast.com</span></a> <o:p></o:p></span></p></td></tr></table><p class=MsoNormal><span style='mso-fareast-language:EN-GB'><o:p> </o:p></span></p></div></div></body></html>
