lambo262 Report post Posted October 22, 2013 Well with that massive and imprecise throttle linkage (6 carbs)...you have wear problems as well. I set-up a countach just for kicks when it was 9 years old with maybe 10K miles on the odo. All the carbs drew the same...and guess what 200 miles later (2) were out because of linkage wear. So...again I would make sure that all the linkage elements, bell cranks etc. were like "new" Paul I don't just travel at low speed, but Albert is completely right. I get my carbs tuned at least once a year by Roberto Grimaldi at Grimaldi Engineering. It makes a big difference to the enjoyment of the car when the carbs are just right, especially when driving in traffic. Grimaldi also tunes them with just a screwdriver and his ears.

Then you can tune the carbs, but just when you are sure the likages are perfect. 1) rebuild the carbs 2) linkage service 3) carbs tuning 4) bye-bye, K-Jetronic... Ciao.

Six double barrel carbs well tuned performing together are a very pleasant and exciting music, arent't they?

ken qv Report post Posted December 14, 2013 Well maybe it's time i have mine done or learn how... it's been 6 years and still no issues with them so twice a year sounds nuts. Quote Share this post Link to post Share on other sites More sharing options...

ken qv Report post Posted December 25, 2013 Have you guys seen one of these yet? a neighbor used it on his Jalpa to tune carbs and said it worked very well. He did it himself! Quote Share this post Link to post Share on other sites More sharing options...

Fortis Report post Posted December 31, 2013 I watched yesterday the Wheeler Dealers Lamborghini Urraco episode, they had an expert in tuning carbs, quite a nice explanation of the process and the tools used. http://cf.cdn.vid.ly/r9s3m5/mp4.mp4 The tuning starts at 14:30 min Quote Share this post Link to post Share on other sites More sharing options...

Albert-LP Report post Posted December 31, 2013 What are carbs? Those things which aren't good in your diet if you are trying to lose weight?? Wrong.

Redlambo Report post Posted December 31, 2013 huh... Anyway, this Ken the hand held synchometers are easy to use on the 44DCNF downdraft carbureted Countachs. However when it comes to using them on the 45DCOE side draft carbureted Countachs they are almost impossible to use. Just changing the air filters in a side draft Countach is a major pain in the ass as you need to remove the air horns from all the carburetors in order to remove the filters.

Albert-LP Report post Posted December 31, 2013 I saw Salvioli using a thing like that when my engine was started on the dyno after the rebuild without the airfilters and the airbox covers. He told me it was "an american made device" that simplified a lot the carbs tuning. But then i had to go to the specialist to tune better them... I do not know how you could use it with the DCOE with the airbox on and even with the DCNF you should tune them without the airbox (i suppose) so maybe you would have to tune them again with the airbox on and without that device. Correct? ciao Quote Share this post Link to post Share on other sites More sharing options...
ken qv Report post Posted December 31, 2013 Hello Vic my friend... i hope you and your red monster are both well. The device i am holding there belongs to a neighbor of mine with a Jalpa so all that makes sense now. He said it was Very easy to use and helped his car a lot i just didn't think of sidedraft vs. downdraft access. Maybe I should pick one up.

Hey Ken, Things are getting better here as I am almost caught up on home improvement / renovation projects. I feel like a worn out, heavy set, broke version of Bob Vila. LOL As far as the synchrometers go they are inexpensive around $40.00 dollars. I have one however I have never used it as I have not had the time to disassemble the entire air cleaner assembly to access the carbs.

ken qv Report post Posted December 31, 2013 Thank You so much Fortis for that Awesome video link!.. i have a friend with a Urraco and i will say that the tuning part of the video is cool but you are ripping yourself off if you don't watch the entire thing. Excellent! Quote Share this post Link to post Share on other sites More sharing options...
