After I blip the throttle the idle stabilizes; I think with a manifold leak the idle would drop again, but it doesn't. I think this could be due to:</div><div aria-label="Compose body"><br></div><div aria-label="Compose body">1) on a warm day, especially, the cylinders 'load up' with unburned fuel and start running too rich</div><div aria-label="Compose body">2) letting the throttles 'slam shut' causes the idle to 'overshoot' to the downside. This is why some cars have 'dashpots' to cushion the lever that operates the throttle(s) when you lift off the gas pedal (I've known cars that would stall if the dashpot wasn't functioning)</div><div aria-label="Compose body">3) idle may be set a tad low to begin with (though, at first, our car seemed to have the 'HD disease;' i.e. the 'choke' springs weren't strong enough to return to normal idle, causing high idle)</div><div aria-label="Compose body"><br></div><div aria-label="Compose body">Anyone got any other causes/solutions?</div><div aria-label="Compose body"><br></div><div aria-label="Compose body">Bob</div><div><br></div><div style="color:#000;font-weight:normal;font-style:normal;text-decoration:none;font-family:Helvetica,Arial,sans-serif;font-size:12pt;" data-mce-style="color: #000; font-weight: normal; font-style: normal; text-decoration: none; font-family: Helvetica,Arial,sans-serif; font-size: 12pt;"><div class="gmail_extra"><div class="gmail_quote"><blockquote class="gmail_quote" style="margin:0 0 0 .8ex;border-left:1px #ccc solid;padding-left:1ex" data-mce-style="margin: 0 0 0 .8ex; border-left: 1px #ccc solid; padding-left: 1ex;"><div><div style="font-family:Arial;font-size:12pt;color:#000000" data-mce-style="font-family: Arial; font-size: 12pt; color: #000000;"><div><div class="h5"><div style="color:#000;font-weight:normal;font-style:normal;text-decoration:none;font-family:Helvetica,Arial,sans-serif;font-size:12pt" data-mce-style="color: #000; font-weight: normal; font-style: normal; text-decoration: none; font-family: Helvetica,Arial,sans-serif; font-size: 12pt;"><div class="gmail_extra"><div class="gmail_quote"><blockquote class="gmail_quote" style="margin:0 0 0 .8ex;border-left:1px #ccc solid;padding-left:1ex" data-mce-style="margin: 0 0 0 .8ex; border-left: 1px #ccc solid; padding-left: 1ex;"><div><div style="font-family:Arial;font-size:12pt;color:#000000" data-mce-style="font-family: Arial; font-size: 12pt; color: #000000;"><div style="color:#000;font-weight:normal;font-style:normal;text-decoration:none;font-family:Helvetica,Arial,sans-serif;font-size:12pt" data-mce-style="color: #000; font-weight: normal; font-style: normal; text-decoration: none; font-family: Helvetica,Arial,sans-serif; font-size: 12pt;"><br><b>Subject: </b>[Healeys] car dies at idle<div><div><br><div><br></div><div dir="ltr">Now that I seem to have sorted the ignition issue I have another problem. After driving the car for a while and I stop at a light, my car begins to drop rpms and will then die if I do not blip the gas. Rebuilt carb, and distributor, new plugs and ignition bits. Could a manifold leak cause this? 3 AM thoughts on the problem. I'm going to try the brake fluid spray on the manifold trick to see if the engine changes sounds while idling.<div>Cheers<br clear="all"><div><div><div dir="ltr"><div><div dir="ltr"><div><div dir="ltr"><div><div dir="ltr"><div dir="ltr">Ira Erbs<div>Portland,OR</div><div><span style="font-family:'Times New Roman',serif" data-mce-style="font-family: 'Times New Roman',serif;"> _______ _______</span><br style="font-family:'Times New Roman',serif" data-mce-style="font-family: 'Times New Roman',serif;"><span style="font-family:'Times New Roman',serif" data-mce-style="font-family: 'Times New Roman',serif;"> (______ \____1959 BN4____/ _______)</span><br style="font-family:'Times New Roman',serif" data-mce-style="font-family: 'Times New Roman',serif;"><span style="font-family:'Times New Roman',serif" data-mce-style="font-family: 'Times New Roman',serif;"> (_________________________)</span></div><div> BT7 engine and disk brakes</div><div><strong style="margin:0px;padding:0px;border:0px;outline:0px;font-size:14px;vertical-align:baseline;background:rgb(0,0,0);color:rgb(255,255,255);font-family:sans-serif" data-mce-style="margin: 0px; padding: 0px; border: 0px; outline: 0px; font-size: 14px; vertical-align: baseline; background: #000000; color: #ffffff; font-family: sans-serif;">Aerodynamics are for people who can’t build engines.</strong><span style="color:rgb(255,255,255);font-family:sans-serif;font-size:14px;background-color:rgb(0,0,0)" data-mce-style="color: #ffffff; font-family: sans-serif; font-size: 14px; background-color: #000000;"> – </span><em style="margin:0px;padding:0px;border:0px;outline:0px;font-size:14px;vertical-align:baseline;background:rgb(0,0,0);color:rgb(255,255,255);font-family:sans-serif" data-mce-style="margin: 0px; padding: 0px; border: 0px; outline: 0px; font-size: 14px; vertical-align: baseline; background: #000000; color: #ffffff; font-family: sans-serif;">Enzo Ferrari</em><br></div><div>Please excuse random auto corrects and misspelled words</div></div></div></div></div></div></div></div></div></div></div></div></div><br></div></div>_______________________________________________<br><div><br></div><div><br></div></div><div><br></div></div></div></blockquote></div><br></div></div><div><br></div></div></div></div></div></blockquote></div><br></div></div><div><br></div></div></body></html>
