if it is spinning over as if there is no compression ( really fast) then remove the plugs and squirt oil in the chambers as you turn the crankshaft. This will seal the rotor seals and give compression.
replace the fuel as it may be stale. fill the float bowl by pouring fuel into the balance pipe in the throat of the carby (When the air filter is off you will see a pipe in the middle of the carby throat point up-- balance tube). Check that the fuel pump is operational.
your tuning is too low,try adjust your carbs tosired point,check fuel filter.if its blog drain it with gas thoroughly then fitted back,start the engine,revs at 1- 5 rpm.if theres no changes, bring your car to your nearest spare parts guys .they will help you out.
Look for restrictions in the intake air and exhaust systems. Check fuel pressure and delivery (fuel filter/pump). Check the ignition system as well. If the engine has a lot of miles, you may be experiencing combustion seal wear. These are amazing engines when they work correctly! Good luck!
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.
Last week my 323 89' Mazda stop working as I was driving it in middle of the street, I pushed to the side. it would not start, the starter sounded ok, but the car just didnt start, I checked the fuses, gas pump, and all seemed to be ok, finally with the help of a friend we found out that the ignition rotor at the distributor wasnt working we then replace it with a new one from autozone , is about 5 dollars, now it works just fine, big problem easy solution.
Nothing wrong with that - some cars are programmed that way. The Mazda RX7 would go to 3000RPM to help get the catalytic converters up to temperature as a way to pass cold-start emissions standards. Don't sweat it.
rx7`s should rev to 3000 when started cold then it should settle to 750 to 1000 after about 30 to 60 seconds. mine suffers a similar problem. so far I have been told various answers, mostly involving the bac valve, lambda sensor, air flow meter, etc. try starting of by adjusting the idle adjust screw (on top of the throttle body under plastic cover) this may be all it is. I have not had time to do mine. Its been fine otherwise and idles fine after a few minutes. mine is non turbo 87.
