Not to dissuade you from putting back a 13B,

but it sounds like that motor might actually be ressurectable... From what you've described, I'd suspect the ignition switch. I've had one fail on me in such a manner that it was impossible to get the engine running unless one held it at a point in between the starting and running positions, just shy of grinding the starter... what a pain! Then there's a host of other funky electrical possibilities... Check all your wiring!
Still, it's pretty common for a motor to get flooded out, 'load up', and refuse to start as a result--even if everything else has been remedied and made proper (!)
The cure: A quick little push/ cautious tow down the street to a speed of 20-30 mph, followed by a pop of the clutch into second (with the functioning ignition in the 'run' position, of course...)...
Try pulling and cleaning those plugs with a little B-12 Chemtool and a wire brush. Check the fuel filter for crap, and the carb for fuel delivery. Check the dizzy cap/rotor for quantity of wear/corrosion, and if needed, use a pocket knife to scrape the contacts carefully clean. (Believe it or not, done right this can work wonders!) Of course, it helps if you have electronic ignition--as long as it's not that screwed-up remote-mount-igniter cross-trigger-hell version!
Last but not least, remember to check for your basic, garden-variety vacuum leak... depending on how much of the stock BS is still on that 12A--or how well/poorly the removed BS was/wasn't capped off... you get the picture!
Oh yeah, almost forgot--you do indeed need a strong battery... and very clean connects...(check/clean those grounds!) Nothing like paint, rust, dirt, and corrosion to add resistance...

Ha, Ha, Ha,...

Duh, I never tried an auto parts store for the fuse. I asked a Mazda parts depot, LOL.

Go figure...

No biggie Klaus, I got it running.
I cahrged the nattery and just didnt gas it up and started right up.
i idleed it for about 45 min just to let this enginebrreath for a while before I kill it.
I can easily rebuild an port the motor but why.
Like I said the 12a is a POS compared to a 13b.
Carbs are dinosaurs.
I apppreciate the advice but im set on a 13b.
Im in no rush. I have other vehicles so this can take as long as it needs to.

That's the only sane way to do this, I'm convinced.

I know what you're saying re: 12a v. 13b and carburation v. EFI but really its hard to speak in absolutes.

There are all-motor (NA) 12a's running in the low 10s. In most forms of racing, carbs when tuned to purpose, perform just as well as EFI.

That said if I wanted big performance with as little trouble as possible I would street port my 13b and add an the camden 5 or 7 inch supercharger with intercooler, holley 4 barrel and intake with RB header and high-flow exhaust.

Figure that's probably good for 250-300 hp and a gob of torque building right from idle. Once tuned that toque curve would look a more like a flat line. And tuning in a holley isn't that hard, and they're a piece of cake to rebuild.

You could build close to 400 horse with a single REW setup probably, but at probably double the price, a LOT of electronics and considerably more fabrication. All in all probably double or triple the overhead. Plus a lot more to worry about.

I flip flop all the time in my REPU fantasies, but just goes to show you there's lots of options. I think about a 13bt like Dan's too. Figure a haltech or something would let you tune for a little better fuel econcomy to go with the power but then there's at least another 500 bucks to beef up the cooling system, etc.

I dunno. There's options galore tho, and the more different configurations out there the better as far as I'm concerned. I love seeing ppl do new stuff.

Right now I'm leaning towards an intercooled supercharged setup to keep things simple under the hood while giving me more power than I really need. Plus I figure it'd be about half the price at least, which sadly is a big factor.

But then I'm at least a year or two away from worrying about that :)

I will most likely duplicate what I did with my rx7.
I have all the componets I need minus the block.
I have the tranny, Intercooler, turbos, radiator, manifolds, ECU, wire loom, and ,motor mounts.
I would need the front cover off a tII appearently.

Not that I am looking to break 10 seconds in my repu but I would like to get it set up with something I am familiar with.

I believe the only reason you would want a TII front cover is for the oil return lines from the turbo. Personally I think it would be easier to tap a new nipple in the 12a or GSL-SE front cover and not have to deal with fabbing new motor mounts. I considered doing a TII conversion in my REPU when I replaced the motor, but time constraints from a work related move forced me to go the carb route.

Merry Christmas, everyone!

12A's don't belong in REPU's. That being said, I wouldn't turn away a running or rebuildable 12A core... could always go in something else...! As to the varying modern intake, etc. options: I'm just so far behind the times/underfunded that I don't even know much about 'em, beyond carbs, which I'm fairly familiar with...
Not that a supercharged/injected/ported 13B wouldn't make me that much more gleeful a target for speed traps...!
I'll keep on dreamin' until that day comes.
(Anyone else wanna build a motorcycle around a 12A, just for the adrenaline factor?) :)

Klaus you can have this 12a after I rebuild and port it.

Are you serious???

That would be MOST kind and generous of you, Dave! Might have to trade you something back for such a gift...
Still, I wouldn't be putting it in a REPU... but it'd be one step farther down the path to wankel nirvana!
How can we all work together more closely, despite the 'Continental Divide'?
We could do great things, under one roof... the whole lot of us!
