morph Posted August 9, 2005 Report Share Posted August 9, 2005 I have just received a shiny manual choke conversion (Holley genuine part) for my Holley 4 barrel. Unfortunately the instructions are in clear English but I only understand clear pictures!!! Their is a perplexing array of nice brass bits which form the linkage. Would anyone be kind enough to email a few snaps of theirs so that I can get a rough idea of the layout. Please, please ,please............. Cheers Morph Quote Link to post Share on other sites
Cinnobar Posted August 11, 2005 Report Share Posted August 11, 2005 Why bother with a choke? Most I know with a 4 barrel do a few pumps with the ignition switched on and off it goes. Mine needs nursing for 10 seconds or so after starting and then it keeps going. Jim Quote Link to post Share on other sites
malcolm Posted August 11, 2005 Report Share Posted August 11, 2005 Agreed! I've still got the rather odd Holley electric choke, but I never use it. Malcolm. Quote Link to post Share on other sites
martynharrison Posted August 11, 2005 Report Share Posted August 11, 2005 Er... if memory serves, isn't this to do with converting the secondaries from vacuum (automatic) to manual operation? I.e. nothing to do with cold starting? Could be wrong. Here are some pictures of my carb, if they aren't high enough quality or missing the relevant part, I can try again later. holley holley holley holley holley Quote Link to post Share on other sites
morph Posted August 11, 2005 Author Report Share Posted August 11, 2005 Martyn, thanks very much for the photos. Interesting to see that a few people have retained the autochoke. When I spoke to Simon at S&S he heartily recommended a manual choke conversion. He also pointed out that some people have their Holley on back to front. Looking at the pix makes me feel I may have to go to the garage for a quick look!!!! (I didn't fit it!!!) Morph Quote Link to post Share on other sites
morph Posted August 11, 2005 Author Report Share Posted August 11, 2005 Phew, The Holley was on the right way around!!! Martyn, you seem to have a complete central heating system on the back of your rocker covers, what's its purpose??? Morph Quote Link to post Share on other sites
martynharrison Posted August 11, 2005 Report Share Posted August 11, 2005 Breather system. It's actually just a foot or two of pipework costing, oh, about a quid or three, and the crankcase blows gas through it so that, unlike before, the rubber hose can't kink and block it and the engine start coughing at relatively low revs when trying to overtake up hills as a surprise. I'd guess most engines don't need that, but mine is doing lots of blowby. I have a version two, and three, in the pipeline (ouch). V2 has the junction the other way round so the second rocker cover is joining the main flow, and v3 is a twin pipe. But I think this is all mainly because my engine needs replacing. :laugh: Quote Link to post Share on other sites
