my car will start up cold but when its hot it wont start unless I push it
its an 83 rx7 with 12a street port rb heads and exhaust I just rebuilt the carb a couple weeks ago

any ideas?

 

yeah rebuild the engine. Test your compression when hot and u will see what I mean.

 

I had this problem when I first bought my 7. Turns out the battery was garbage. Have yours load tested to see if it's the culprit. Good luck.

 

I bought a brand new battery

 

Have you adjusted the idle?

 

i can make it idle fine i dont think thats the problem tho

 

My GSL has a hard time starting hot, but it just takes a bit longer to get going, but it does start eventually, sometimes it takes up to 5 times of turning to get it to start but the carb is crap so that could be why. Are you sure it can't start while it's hot? Have you tried multiple times before pushing it?

 

I try about 3 times I usualy dont like to put to much load on the battery I dont want to kill it, I will test 5 or 6 times to start it

 

Do you have hot start assist?

 

Rotaries that have hot start issues either have a rich issue, flooding, or low compression...

 

thats also why they have a hot start assist

 

no I dont have hot start assist so I hooked up the cable to the hot start assist and had a friend pull the cable while i started it still didnt work

 

Start by checking your timing. If that's good, then pull the cover off the air cleaner and see if you have fuel pooling up on the butterflies.

 

Don't know what your problem is then, since you said you rebuilt the carb. My carb is in horrible condition and i need to rectify that, so i don't know what you need to do, maybe your ignition coils or plugs and wires? If all those are new then i wouldn't know, i'm not a mechanic.
