Angry Whats up with Rx-7 flooding???

I have 84 gsl an 87 N/A and a 10th Annivesary. I dont have a problem with the first gen flooding just the 87 N/A; when its warm it is a bit hard to crank back and my 10th AE, which is rebuilt now with 3000 miles on it, will not start back when it has warmed up at all. I have a fuel cut switch but I want know why it wont just start without the switch? I hear alot about this but what is the common cause for this chronic Rx-7 plague? I want to correct this problem.

As scott mentioned it is mostly caused by leaky injectors (remember that the injectors fire 3 times a cycle in a rotary, as well as almost no one ever gets them cleaned and keeps the fuel filter and fuel tank clean) or low compression.

Is it safe to use injector-cleaner, or should I disassemble the little bastards and clean them manually

If there is a flooding problem the only real answer is to have the injectors professionally cleaned.

If they are not leaking, there are a couple of people that suggest using double or triple the mix in the fuel tank injector cleaners occasionally.

I see nothing wrong with occasionally using a double strength of fuel injector cleaner as long as the cleaner does not sit in the tank for too long.

I am going to do a compression test. If that turns out ok I am going to send my injectors to Rc engineering to have them cleaned and to hopefully fix the problem.
