I was running a set of the 260Z carbs ( I got them free - no surprises) on my C210, and they went like the clappers, until I ran the car low on fuel and fouled them up.

A lot of the complaints about these carbies are they are a pig to tune (many carbie places won't even touch them!), and they suffer from vapor lock issues when things get hot. My theory is due to the bigger grill the under-bonnet temperature of the C210 may be lower than that of the 260Z, so this may be less of an issue for you.

I don't expect anyone to back me up with this, they are a generally much hated carby, but if you already have them, give them a go. Worst case you'll have wasted a few hours and will have to put the single carb back on...

By the way, they do bolt straight up, but from memory you will need to modify your linkage and block off a few loose hoses. Actually, now that I think about it, getting them on and off was a bit of a pain.

Finally, if you have the 240Z carbies, then I wouldn't hesitate to get them on there; all the fun, with potentially far less grief.

Yep, those look like the 240 carbies.

It should run better, and more economically, because the twin manifold allows the engine to breath a bit easier.There should be a small cogged wheel on the underside of the carby that allows adjustment of the fuel jet for setting mixture. The 260 carbs didn't have that adjustment.

    • Oh and I lost my headlight washer jet cover!
    • Ok, so I got myself some X1 wheels really cheap to try out, they're a bit different and I like them but they're really narrow (18x8) they are available in staggered 18x8/9 also but really hard to find.  I kinda dig them, but not as much as the F10 19's I usually run, so these go into the wheel pile.   As I mentioned in another thread, I got a new exhaust. It's an off-the-shelf stainless one that fits OH-KAY. I don't love the tips size and how far they come out the back, I think I might cut the tips off and replace with some smaller (~3") ones that don't extend as far. It sounds really good though, I'm not sure if its just in my head but the car feels a little quicker, more responsive.    I fitted an eBay special front lip. Surprisingly it fit perfectly and all holes lined up. Its a little rickety but I haven't put any double sided tape on yet, I want to clean the front bar up where it has scraped the road a lot and fil in the number plate holes (or, get body coloured wrap to cover them - is this a thing?  I'm not sure if I'll leave it gloss or pain it matte. I really like it though, I don't particularly like the front bar without it, I don't really like the M-Sport and to get anything else is just too expensive. That said, I might need a new one now anyway as I dropped the car onto the jack after forgetting to put ramps under the front wheels. It bent a lot and while it did go back to normal after I got the car off the jack, I do fear I have not done it any favours.   Lastly, my headlights died. Different problems in each. They have gotten much dimmer over the past year or so, I put new (uber expensive) OSRAM bulbs in them but to no avail. One of them pointed at the ground and the other just kinda did its own thing with light working sometimes. Yeah, check this 18 year old BMW headlight wire. I reckon I know why they were stuffed.       BTW, the yellow and black is the power to the Xenons. Yikes. I hunted around an researched my options here. I would have loved to just get a replacement harness but not a thing. My car has adaptive headlights, that is they rotate left and right with the steering wheel. Good condition used adaptive xenons were over $700 each, non adaptive were around $400 each, but I couldn't help but think that they're all around 18 years old now, surely they'd have the same problems. So I looked at newer LCI headlights but they were even more expensive and I couldn't confirm that they'd be plug and play with lots of people having lots of opinions so not worth the risk.  I ended up getting brand new Chinese headlights from MARS. They're very close to OEM with only the angel eyes being a bit different. I didnt want crazy turn signals or sharp DRL's or anything. Not my bag.  They're not adaptive, I thought thats a feature I wouldn't really miss. So I coded that out.  The lights are awesome, they look so nice and they take so many years off the car. The angel eyes look great and the headlight brightness is ridiculous. I was so used to the old ones, I didn't realise just how bad they were. The new ones use the OEM bulbs, Xenon ballast and leveller motor which I was happier with. The only issue with them is that the rear cover is held on by SEVEN screws. This will be a nightmare to get to and open when I need to change bulbs.  
    • Now that you mention it I can see those too. More subtle. The lighting and low resolution makes it hard to assess super well what's going on but what is visible is bad enough to pull the motor.
    • I feel like this is due an update
    • Yeah, I wasn't giving two f**ks for the ring running around the bore. I was looking at the vertical scratches running up and down across the hatch marks.
