I did not say crank them up tight. I wrote, ?But split washers, even two stacked, are much more stiff than a Thackeray washer, and they don't provide the degree of compliance needed to let the soft mount do it's job.? I?ll stand by that statement. And unlike you, I made no assumptions, or comments, about how tightly you cranked them up.twincamman wrote:what ever !!!!--think about it !!!! --YOU DONT CRANK THEM UP TIGHT --GEEEEZ you think like a Chevy guy -ed
Esprit2 wrote:Lotus' unique mount was die-cast metal and had a tapered, funnel-shaped bore which extended slightly to one side, forming a lip. The mount is to be installed with the funnel pointing toward the engine (large diameter toward carb / small diameter toward engine). There are some strange, complicated flow dynamics inside an intake manifold, including reverse flow. The lip is a dam meant to inhibit a reversion wave from reaching the carb and messing with the calibration. The funnel & lip may look restrictive to the eye, but the net result is really an improvement in flow and mixture control. It was a Lotus innovation.
