Mikey UC Posted April 30, 2003 Share Posted April 30, 2003 There was a time not so long ago that I had my Webers set up pretty much to my likings, however since then I have fiddled… Previously when I lifted off the accelerator the car made oodles of lovely popping and banging noises and the revs dropped away quickly. Post fiddle however the engine now feels smoother, the fuel economy has increased (I made it from Bath to Reading on half a tank) but there are no pops / bangs and the revs take longer drop when lifting off (before some corners I was able to just lift off to reduce speed, now I have to break). I have checked the throttle return spring and this seems to snap shut as well as it ever did. Can altering the idle mixture and/or carburettor balance have an effect on revs not dropping, and where have my pops and bangs gone? – No self respecting x-flow should be without them. Thanks for any help Mikey Link to comment Share on other sites More sharing options...
Smegnoguk Posted April 30, 2003 Share Posted April 30, 2003 I've been trying to get rid of my pops and bangs! Is that where I am going wrong? Link to comment Share on other sites More sharing options...
chrisb Posted April 30, 2003 Share Posted April 30, 2003 I've just had a dry sump kit fitted to my x-flow. The carbs had to come off to do this. (Twin 45 Webers) Took it out at the week-end, and yes, it pulls better from low revs, idle's nicely, but its stopped popping and banging on the over-run ☹️ I would also like to know what has affected this. I really miss driving it at night, and lighting the dry stone walls up with fire as I pop and bang my way down the country lanes.

aclucas Posted April 30, 2003 Share Posted April 30, 2003 If anyone has any spare pops and bangs, I'll take them. My K is very anemic in that respect ☹️ Alan N7CTR 1.8VVC Link to comment Share on other sites More sharing options...
I reply to every thread Posted April 30, 2003 Share Posted April 30, 2003 Chrisb - You've probably cured the air leaks that you had before so don't get the bangs. My VX creates dull booms on the overrun together with a flame about a foot long. Wash it without a plastic sheet over the engine & you get a bang display that gets the neighbours calling the Environmental Health Dept. Link to comment Share on other sites More sharing options...
