Thanks mate!

Good question re the device with the pulley dd. I still have no idea. I mistakenly thought is was an A/C compressor at first, but mainly because I can't think what else it could be. It might go some of the way to explaining why the previous owner had it. I know he didn't have electricity running to his workshop (he lived on a rural property) so it could be something to do with his machine shop equipment.

The motor has actually now been sold. Just locally through word of mouth in the end. Can I cancel the ad somehow? My first time advertising on the forum.

Cheers everyone.

I have an A12 for sale. Block number 174994E. The condition is unknown. I found it while helping a family friend clean out her late husband's shed/workshop. He was a mechanic who ran a small machine shop in his later years. It looks like the motor was being set up to run a generator or water pump. I really do not know unfortunately. I couldn't see any signs of how he was going to cool the motor, so I don't imagine he had it running as he wanted before passing away. It was stored outside, but under cover. The motor is bolted to a custom support frame that sits freely on a dolly. Both support frame and dolly will go with the motor. Handy to push it around the workshop for the next few years until you find a use for it!

Air cleaner housing and distributor cap are missing, but otherwise seems complete.

Full disclosure, I am just passing motor on for the widow. I thought I'd firstly show it to the Datsun forum which has been so handy for me over the years. It's not currently advertised anywhere else.

I am in Woodend, Victoria, Australia.

Price is a tough one. I'm really just trying to get a few dollars for the widow. So please make an offer. I'm thinking a couple of hundred or so. It's negotiable. Hoping for a quick-ish sale, but it will depend on interest. Happy to PM photos if you like.

Cheers.

Hi, I've just acquired a complete A12 that has a compressor attached if you're still interested? Happy to get some pictures for you when I grab a minute. I'm in Victoria. Cheers, Stuart

Hey,

I'm looking to upgrade my fairly stock a12 with the purchase of an a14 or a15 head. Keen to hear from anyone who might want to sell an a14/15 complete engine or just head alone. Preferably in Victoria, Australia but happy to pay for postage or sort out delivery to Vic, postcode 3442.

Thanks

Is there any rough limit to how far static advance can be though (just out of interest) before it may have a detrimental effect to engine at low speed? Probably no reason to set it too far advanced unless you're compensating for a malfunctioning mechanical advance mechanism or something, but would you anticipate any problems setting it a long way from spec? Perhaps all is good as long as it's not knocking anywhere in the rev range??

Yeah mate, all good :) I guess I'm interested in knowing what static timing and total advance people are using. And what revs they are getting total advance at. Having said that, I should go and read the wiki entry for this first. I'm sure there's something there...

Thanks for the threads. Informative as usual!

Thinking of just using a pertronix ignitor kit now for ease of purchase and installation. Preliminary investigation seems to suggest they're considerably cheaper to buy from the U.S but I'll look around.

Re: dizzy weights, I filed a little bit off my weights (where they hit the stop) to allow a few more degrees total advance after I read that a few more degrees total may be beneficial. It was years and years ago though (when I knew even less than I know now...so not much!) and I didn't give much thought to how it affected the progression of advance. Anyway, would be interested to see what curves people are using for different stages of engine tune.

I was just wondering how people have gone about drilling the hole through the E15 distributor shaft to install the a12 drive gear. Fairly important to drill directly through centre of shaft i'm assuming. Best done by a machine shop? Perhaps you just use a decent drill press and holding jig/clamp?

Also, do you have to provide a new roll pin or can you use the old one?

Cheers.

Yeah as supafatto mentioned, the float bowl should be towards the front of the engine. Best to set it up this way as it avoids the fuel washing up against the float bowl wall furthest away from main jets under acceleration. This has the effect of locally lowering the fuel level in float chamber over main jets which causes a lean mixture. If you set it up with float bowl to the front (as suggested), the fuel will wash up against float chamber wall over jets causing a local increase in fuel level over main jets instead. Arguably this makes for a richer mixture, but it's better than lean!

See pm too....
