  1. i sold my oldtimer car that was equipped with this carburators. I still have a Dyno JetKit, new, not used, with set of DCO plugs. If somebody is interrested please let me know.
  2. 1.6 i think my setup is not as it should
  3. is there some kind of compare list when it comes to jet's ? i would like to compare my 1.6 setup with others.
  4. both can be done, it is not neccecery. I use a little reservoir because my headlamps are also vacuum powered. I use a festo switch to switch the pump on and off. switch
  5. i used a second hand vacuum brakem pump for that purpose, one like this
  6. what kind of electric fuel pump others are using with this carburators ? what maximum pressure could i use ? thanks.
  7. hi, it has been a while, last season i drove the car like it was, because i just wanted to drive and not have the car on the ramp all the time. Now the new season is there, just drove the car again first time this year, liked it a lot ! AFR gauge still jumps to 19 all of a sudden. Last year G-Duax said it could be i am sucking the carbs dry. Before i gonna reroute the fuel lines and maybe upgrade to a higher volume fuel pump. i would expect the cat not running smooth when the carbs are dry and i push the throttle ? or am i wrong ?
  8. today i got the DCO500 plugs, they are little ! maybe i should have checked before, it seems that my carbs are a bit different from the carbs on page 63, seems i only have a pilot air jet ?? any sugestions ? No time left today to look into the DynoJet kit, hope that will fit :confused:
  9. okay, should't i notice that in behavior ? engine seems to run fine at those moments, can push the throttle, car speeds up. runs smooth.......
  10. Got my DynoJet kit, hope to have some time these weeks to expiriment with it. Do i understand it right that i could use the DCO500 plugs if i expirience a sudden jump to value 19 if i drive a continous speed ? When i drive the highway for example 120 kmh for a longer time suddenly the afr goes to 19. i have to slow down or play the throttle to get i back to normal. than values stay right for a time an suddenly jumps to 19 again. thanks
  11. would this be the kind of DynoJet we are talking about ? http://www.ebay.com/itm/Dynojet-Research-4165-Jet-Kit-Stage-1-/141698008085?hash=item20fddc0415:m:mZ9YJSNM4I4EgeuL0fJUNhA&vxp=mtr just tested WOT, readings change depending RPM. At low RPM AFR 11+ going up to between 3000 and 4000 RPM between 12 to 13 AFR
  12. Thanks for all response ! Have some work to do. Thanks pointing me to page 63, i missed that post completely. Gonna try one of those DynoJet kit's, i check if it is availeble in Europe or find a way to not double the price while shipping. With last modifications to my inlet manifold i made vacuum tubes that i use for vacuum to my MegaJolt, also use it to calibrate my carbs using a CarbTune Pro. Now that i can use my CarTune and have a AFR gauge i can really get into it. Never looked at timing really, car runs fine. I gonna get into this now that i can measure the effect on combustion. Right now i am glad to have mostly safe values on cruise and idle. Gonna try WOT and post my readings. thanks !
  13. thanks for the reply ! yes, you are correct about the 19 and 12.8 situations. sorry for my rusty English. after adjusting #8, first al way in and then 5 turns out, mij idle is now about 12.5 so this is much better. I can turn it a little back in. At WOT i have to check, i am not at home right now, gonna test it this weekend. I have to check if the needles are ajustable, if not do you know what needles i should buy (on ebay) that fits these carbs ? If i understand you correct; - if WOT is about 14.7 than adjust needles, - if WOT is far high or low than first change #14 main jet Idle is now quite okay with little open throttle is still get readings 19, after giving more throttle a steady 12.8 on highway or when i drive city traffics values are jumping up and down. To get better values on little open throttle do i have to place a bigger #16 pilot jet ? thanks again !
  14. hi, I do not own a Datsun, i do have a motor carb setup on my Matra Murena 1.6. Hope you don't mind a ask a question about this setup. did read a whole lot of information in this topic, because i'm not very familiar with carburator setup adjustment i want to ask some questions before i going to adjust the wrong way and damage something. Like i said i own a Matra Murena 1.6, it is a 1982 4 cilinder car with a Mikuni (Yamaha) 5LV1 37mm carbs. Ignition is by MegaJolt with MAP. I bought this car a couple of years ago, the motor carbs where allready there, also was a custom made airfilter box mounted. Last years i did some modification, i replaced the airfilter box with open filters. Mounted MegaJolt etc etc. This car is just a nice drive, it has a nice sound and good looks. It is not a race car, and that is how i like it. I just drive it for fun and i want it to be healthy. Because i did have backfire's i wanted to check the fuel mixture and mounted a ASPX Wideband AFR gauge. Now that i know that values are not as it should be, i want to fix it. When the car runs idle or when i open the throttle just a little my AFR reads 19. When i drive on the highway about 120 km/h (3500 rpm) the values are steady around 12.8, when i push the pedal it goes down a bit, when i let loose the pedal it goes up a bit. Reading this topic i think i might get the 12.8 value a bit more to 14 if i lower the needle a bit (should i or is 12.8 not a problem?) What should i do about the 19 value ? Is this something i have to adjust with jet's inside the carbs or should i be corrected with pilot air jet screw ? thanks for youre help !
