Hi all i have got my l20 running again with some side draft 40 mikuni,s. My car war running well with a 32/36 dvga weber and extractors timing was spot on. I have since fitted headers and the side drafts as mentioned and it idles ok, sounds a little rough haven't stuffed a round with them to much yet. Getting to the point, when i go to rev it up it splutters a bit, flames and pops it has revved up on occasion but Ive shut it down as i am still sorting out linkages (jamming). My thoughts it could be damaged mixture needles or do i need to play with jets.... have thought of buying a rebuild kit.... anyone had experience with these carb's ? |

Get your linkages sorted first. Use a center pull cable & set them up similar to the old factory alfa carbs. You cannot reliably tune side draught carbs until the carbs are synchronised perfectly. For some years now I have refused to tune side draughts using levers & rods. They will NOT stay in tune. |

As Baz said get them close as possible in sync set the timming make sure the jet blocks are tighten down as they can back out due to vibration. I have Mikunis and I love them. Find a toyota RG guy he'll know how to tune them up better. main 130 air 160 should be close enough to get running |

Backfiring and popping is usually a lean mixture |

That's true, but poor sync will give the same effect.

http://www.rmcarburetors.net/index.htm get in contact with him, and you'll get the best setup available. No Questions asked. If I get back to Goolwa and find the linkage kit I'll sell you the one I had made years ago but only used for a few weeks until I rolled the car. Cheers Jordan |
