Backfiring is a sign your running out of gas. You need to check fuel pressure to confirm. This is the first step. It could be another issue but without testing components its all just a guess

My 1985 mazda rx 7 1.1 gets glowing hot where exhust comes out of the motor , replaced exhust pipe and muffler but didn't help have any suggestions


Hi,
Check the ignition timing.
Make sure the fuel you are using is specified for engine use.
Last one will be to check the catalytic converter if it still open.

Hope that helps!

Tip

To that one guy saying its never normal for a motor to burn or use oil and its...


Believe it or not, it is normal for these engines to use about a quart every 2000 even when they are essentially new. Note that I said, "use", not "burn". The combination of higher compression and operating temperatures causes oil to pass through the engine. You might notice your tail pipes have a good coating on the inside. I managed to slow the process by converting to Mobil 1 0W40. I get much better performance and I only use a quart every 3500-4000.

1985 rx7 13b will not hold idle


A large rubber hose feeds air to the large block with "RE-EGI" cast into it. Between that intake hose and the RE-EGI block, called the dynamic chamber, is the throttle valve. You can adjust the idle speed by adjusting a screw in the top of the throttle valve to 800 rpm.

Mazda rx 7 rebuilt kit clutch master cylinder.


crack the bleeder nipple on the slave cyl and get some one to slowly push the pedal see if any fluid shoots out if not you may have killed the new seal in the master cyl.
it sounds like you did every thing right its just that old cylinders get were in them and if you don't hone them out and put a new sleeve in them quite often you will rip the new seal apart on the first pump of the pedal.
any way check for presser and let me no
