Just curious of your experiences, how'd you do it, results, what nots!



I'm still dealing with a flooded motor...

 

Yup! I did when I was trying to dial in the stand alone MAP-idle when I first installed it (rich)

pull out a leading plug(s) and squirt about an once and then turn it over...It will smoke like a bitch probably and you will have to get new plugs. Chances are there fouled and thats the reason its not starting... You might get it started just by getting new plugs.

 

New plugs, good starter, used a fresh different battery from a diff car, it's got spark on the leading, got gas (you should see the vapors coming out of the exhaust)...



Did you have any luck with the simple unflooding or did you just use ATF first?

 

We started with the simple, then complex methods at rx7.com.. they work

Yep, I have to all the time.

Why don't you get a tow around the block in 2nd gear if you are afraid of the atf?

 

Not afraid of the ATF, just haven't gone to the store to get it yet!

Just curious as to peoples experiences so that I can gauge if I'm screwing something up...

 

I've always been able to deflood a rotary by flooring the gas pedal, and pulling the EGI fuse. I've never had to pull the plugs, even on my 88 S4 that had low compression.

 

It doesn't have to be ATF. A heavy motor oil, like 20W50, will also do the job.

 

I have only used oil or ATF to unflood a motor when it is spinning fast. You can hear it sound like the starter is spinning on a gear, but the motor is turning. That kind of fast.

99% of the time I have tried to start a flooded FC, you can just hold the gas pedal all the way down.

 

That describes the sound! Another question, do you all turn the motor over by hand and inject ATF in each housing trying to get each face of the rotors or just into one and it'll work?

 

when i did it i just puled the injector and ign. fuses and turned the motor over a few times after i put the atf in. put the fuses back. fired right up. make quite a stink tho.

 

pulled trailing plugs, cranked over by hand with a little squirt into each combustion chamber/rotor face.

Then put the plugs back in and cranked it up on the first try.

 

 

A bit simpler way than above.

The bodyshot next to Mazcare in Atlanta hired some dum@$$ who moved my car 5 feet & turned it off without full warmup. That's the "I got 0 compression, the engine just goes wrrrrrrrrrr instead of chug chug chug when craking" only ATF will fix this problem" type of flooding.

A pump can, ATF, & rubber hose is what I used. I think most rotaries have a nipple on the intake manifold you can hook up to. Here's the one on a 2nd gen highlighted in Redish Pink:



6-9 pumps, 8-12 sec of cranking and she starts right up.

 

Used the ATF just about every spring since 1993 ('89TII). After the car sat for the winter and if I neglected to start it up every couple of weeks, the engine would just spin, not flooded, but low compression. As soon as I turned the starter I could tell by the speed in which the engine turned over. No resistance. Could have been weak springs, but after a little atf, put plugs in and it would fire right up. Heavy smoke, then it would be fine. Even had compression tested and it was fine. Did put a new engine in 2002 (160,000 miles). Compression was over the minimum, but it was time. I injected the atf into the chambers with a medical syringe.
