Justin: Jamie just said what I was about to say to you. HAIKAL'S NIKKI CARBY IS NOT A GEMINI NIKKI, AND NOT THE SAME AS YOUR NIKKI CARBY. From what everyone has told me today, NOBODY MAKES AN AFTERMARKET FILTER FOR THIS CARBY. A few of the shops I went to today have Gemini filters off the shelf, but like I said, this isn't a Gemini carb.

 

go to the wreckers and get a filter housing off an 808?

 

Went to 2 wreckers today, couldn't find any old Mazdas (well, not an 808 or a 1600 or anything that had a carby that looked like the one we have anyway).

try ausrotary. you could also probably get one off mazdajon who writes the japanese restorer, or he could point you in the direction of someone who can get you one

If efforts to make up a simple housing don't work (after all already have the bits to make it fit on the carby), will go in search of an original 808 or 1600 housing...

Also should probably add that with the Mazda Nikki carby, didn't need to use a spacer under the carby, or shave the manifold. Just bent the spring return tab on the throttle linkage inwards and it cleared everything :( And, didn't have to drill out the throttle linkage either, the throttle cable fit straight in!

if there's something you can rest the filter on, like there's the throat lip on a K aisan carby, you can just make two round flats of metal, cut a hole in the middle of one, and use long bolts and some nuts to hold it together. just make it to suit any filter you find at supercheap, maybe the stock corolla one so you don't forget the part number :(

 

can provide dodgy diagram if required

No, nothing to rest filter on, but current idea in head resembles your idea :( And yes, planning to use stock Corolla filter. Now, if only I had a Milo tin lid or something, that would be perfect :D

haikal should have one from his last exhaust tip :(

Strangely enough, he doesn't! He's only got these dinky little ones, no fun... Maybe I can use his baking tray, but then he won't be able to bake cakes anymore, and that's no fun :(

A few hours of mucking around, and...

 

 

:)

 

Now I just need to do something about the vent in the tappet cover...

 

The car runs SO MUCH BETTER now, starts easier and everything too. Only problem is it runs on a bit after you turn it off, not entirely sure why. Probably fuel mixtures all wrong.

hey, fook.....the looks identical to the carbs all the datsun "L" series used, like from a 510, 610, 710, truck, etc

give that a try.....

Nick: No, no fuel solenoid. In fact, this carby has virtually nothing on it. It has 1 input (fuel), throttle cable and choke. And that's it. :)

Damn Auto choke BS

The only time my auto choke ever gave me a problem was after last skidpan when it jammed shut and would not open, Nothing wrong with an auto choke when its working properly, I get in my car, turn the key and drive..

maybe richen the idle? retard the ignition a bit? vacuum leak? adjust valve clearances? decoke cylinder head?

Could be a vacuum leak I suppose, although I've got new gaskets through the whole carb. Didn't use any gasket goo though, I ran out. Valves sound ok, they sound better than Pinky ever sounded. But could check them to see if they're actually adjusted right. I think ignition is set at +10 or +12 or something, I forget.

 

How do you richen just the idle? Turning the mixture screw seems to change the mixture on throttle, but the idle doesn't actually seem to change (up or down). So... an overly rich mixture can cause it to run on?

So... an overly rich mixture can cause it to run on?

 

not really. more a symptom of a lean idle.

 

is the idle speed screw wound in much, or just touching the throttle linkage? how many turns in is the idle speed screw from just touching the linkage? also the idle mixture screw, how many turns out from just seating?

 

how badly does the car runon?

 

what are the sparkplugs like? condition? heatrange not to hot?
