Sat for 10 years
So my rex sat for 10 years before it was started up recently. and ive noticed now that it is harder to start up than usual (possibly because of cold weather, 30 degrees), i have to have somebody working the gas and choke in the engine bay when starting it up to get it running, but once its running, it will stay running. do i need to get a tune up done to rex? and if so, should i look for a rotary specialist in my area?

1. Drain and replace all critical fluids: oil, coolant, brake fluid. I need to replace the clutch master cylinder so that will get new Dot 3 as well.
2. Replace the plugs, distributor cap, rotor, coils and the plug wires.
3. Drain and replace the gas.
4. Rebuild the carb although that's probably a little compulsive. A good cleaning should suffice.
5. Grease all the fittings.
I think that a 6 pack of Yuengling Lager is a good pairing for this job.
If you don't feel comfortable doing this yourself, then by all means take it to a specialist and have them do this which basically is a major tune up.
Good luck!

If the plugs are wet, then the carb could be set too rich. You might want to try leaning it to see what happens.

"Leaning" refers to adjusting the fuel/air mixture so that you are delivering less fuel as a ratio of fuel/air to the engine. When a carb is running "rich" it is delivering more fuel and when running "lean" it is delivering less fuel. I'm just getting back into working on my RX-7 so I'm not real familiar "yet" with tuning the carb.

you don't wanna warm the motor up too much before driving, especially with the choke, all you're doing is putting gas in the oil

A Haynes manual would be a good investment and will walk you through the steps. As rxtasy3 said, it's important to clean the gunk out so when you pull the carb, it's a good idea to soak it in a tub of carb cleaner before you begin the rebuild. Just wear rubber gloves, that stuff is very corrosive and toxic.
Or, just take it to a local Mazda tech who can easily do the job.

Damn! I had a 81 that sat for too long too. Like what the other guys said. Go through the car make sure everything is good and rebuild the carb. Buy yourself a manual for the carb, do some ******* RESEARCH and you'll be set! Its annoying when members start threads about stupid ****. Everything besides info on the carb is in the FAQ section. Good Luck with your carb and hopefully you'll gain some common sense along the way bro. I dont mean to sound like a *****, but this subject has been beaten to death so its frustrating when every thread is the same questions...

I went to Ebay punched in mikuni got over 505 items. Including carbs, jets, rebuild kits and a manual. On youtube theres a few videos on them but nothing useful. Installer67 has a thread with a bunch of info on webers, it will at least help you understand how 2 barrels work and the diagrams might be useful to you. All this info only took me 3 minutes to gather. Now you have no excuse if it seems like too much like other members have stated just pay someone else to perform the work. Good Luck

"its a mikuni." That's a carb. And I don't mean pasta.

he doesn't know what model of carb it is. I think he knows its a mikuni. but I don't know **** about those carbs. maybe there's only 1 mikuni carb, and they got big just off that 1 bad *** carb IDK. but you don't need to insult the guy. I've abused substances and have had my share of short term memory. and I understood what he was saying. his grammar isn't the best, but who's is. certainly not mine.

The main issue here is that you don't seem to be doing much proactively to get the information that you need. It took about 5 seconds for me to locate the Mikuni factory web site. From there, you can find out all kinds of info about the carb, parts and availability. As a last resort, send them a direct message asking for help. We're not talking rocket science here, just common sense.
Finally, grammar does matter.
