@ micra king
well first of all sir its because k11s are import cars here in our place and its pretty hard to get spare parts. second my throttleboddy was acting up since my maf sensors are down for the count.. third need more flow and finaly, efi tuners are a very rare breed here since the technology to tune ECUs are for people with VERY deep pockets xD |

Well done you getting it up and running fast. Looks like the carbs could do with a full rebuild and clean to make sure your getting the best performance.

nice one aki ;-), i think most variable venturi carbs like those use the profile of the needle rather than jetsize for the metering/air fuel ratio (akin to the old SU carbs, which used 1 jet size and hundreds of different needle shapes) and the acceleration enrichment is controlled by the rate at which the dashpot is allowed to lift eh

@turbo
yes sir my k11 was already converted to left hand drive when i bought it. @frank i will keep that in mind sir and will check the needle settings too. thnx for the tip. @micra king yes i will be doing that sir.. im still under testing stage right now but i will do a full rebuild and cleaning when everything is set.. even planning to buff them up to make em shine :) |

@SFJ
im not really concerned on fuel economy since im after the performance improvements.. and yes sound of the exhaust is different compared when it was still efi @sportsclassic im using stock ignition system sir.. will be changing to coil packs soon with msd when i save up some more cash xD.. and yes i changed the fuel pump since the stock one had too much psi |

update:
right now im forced to chage to headers since the intake did a lot of improvements but the current exhaust is stock.. the engine is choking when i get the rev upto 4k due to over restrictive exhaust manifold..its like when you need to sneeze but there are a lot of booger on your nose that's clogging up the air flow :D will post pics soon.. |

lol found the problem.. the timing was too far advanced and had to turn it down a bit.. now running under 155 jets and working fine.. better throttle response compared to the EFI. |

maybe it sounds like that cause my mufler is directly below the driver seat. no more pipe extension to the rear.. its just headers, a couple of feet of pipe, then muffler.

@LonePhantom
thanks..i did get lots of power and instant throttle response compared to the efi. @sportsclassic well all sensors connected to the throttle body were removed since they are of no use anymore.. the only things connected to the ecu is the dizzy.. but will change it soon when we find some replacement dizzy that doesn't need the ecu to run it.. and maybe put an MSD so that i could play some more with the fueling.. |

your ecu might need the t/p/s signal to give you the right ignition curve eh frank |

been having trouble since got the heads ported and shaved.. major improvements on the 3000 upto 7200 rpm.. BUT.. engine stalling if running the car below 3000 rpm.. hesitating and sounds like coughing.. but when i rev up the engine upto 3000 rpm and above, engine goes wild even outran my buds 1.2L honda hatchback last night with my rpms all out to 7200.. sad thing is undrivable in traffic bcoz engine dies if running it under 3000 rpm.. |

thanks for the tip sir.. will be checking on that as soon is i get home.. currently out of town and be back maybe by monday.. will also be checking the idle jets too maybe they are the ones causing the problems.. oh by the way, just to confirm, the timing chain count for cg10 is 9,7,11 right? thanks in advance |

update:
took some time looking for the problem.. timing chain was fine.. new set of spark plugs, new set of high tension wires.. and found it at last! ..dizzy was f*cked up and had to be fixed.. my bud had to change what he called "condenser". all is well now but engine running a little lean since the port and shave, i guess more jet tuning have to be done.. anyways will post vid with the new rhythm of the engine when i get a chance.. |
