Angry rebuild problems

ok here we go. i just rebuilt my 86 n/a with all new seals including milled out rotors. so i have 3mm apex and an agressive street port. I also removed the 5th and 6th port sleeves when i put it together. I now have every thing together and the damn thing will not start. yet it will turn over alllllllllllllllllll day long, and flood every time you turn the key more then once. i have actually had it started for a record of 1min and 30 sec but i had to stop giving it gas and the exhaust manifold was glowing red hot. I followed rx7.coms unflooding procedures to the tee. and i repeated about 30 times including getting new spark plugs, battery, and 20w-50 oil cause the other **** was gasoline soaked. i also have good compression, i am at a total loss can anyone help me out.

you have to pop start her. Fresh rebuilds dnt generally have very good compression until the seals are broken in, so the cranking motor probably isnt turning it fast enough to build the compression needed.

The exhaust should not be glowing red hot after only 1min and 30 seconds. If that is true then something is seriously wrong.

Since this is a car won't start, then i suggest you start with the basics. Make sure the injectors are not leeking, change the fuel filters. check the spark. Check for vac leeks. There are several reason for a car to not start. Start searching the thread and good luck!

if the turbo is glowing red after a short while of time your timing is most likely not correct fix your timing and from there issue with starting it dont go down a hill get a friend to pull you around the neighborhood in a truck and sit there popping it in gear every now and then but make shure you fix the timing before any of that

yeah, sounds like the timing is retarded.

don't push start the car yet, correct the timing, unflood the motor (pull out plugs, pull egi fuse or disconnect fuel pump, crank til it stops putting out a mist of fuel) and put some marvels mystery oil in the combustion chambers through the plug holes, it will help build compression when cranking after the flooding has washed the lube away, just a capful per rotor is enough. easiest way i've found to get a flooded rotary started.

how do you do the timing without the car on?

restab the CAS and set it in the middle of the adjustment slot, that brings you very close. if your cas is correct and your still running red hot, pull the plugs and do a compression check.

I disagree with those that say "pull" your car around becasue the compression is weak on fresh rebuilds - its total bs if the rebuild was done right. if you have to "wear" in parts something is out of spec in the first place - usually a rotor housing.

Okay, first of all you SHOULD be addressing the glowing exhaust manifold problem before pull starting it (as a few people suggested).

To elaborate on what Mr. Gadget was saying, rotate the main pulley until the yellow mark is lined up with the timing mark on the water housing. Pull out the CAS, and adjust the dot on the driven gear with the arrow on the CAS Shaft housing. Put it back in, be careful to keep it lined up, the gear teeth like to move. Your car should now be timed close enough to run.

Another possiblitiy for a glowing exhaust manifold, AND the reason it's not starting right: Are your cats clogged? You may want (need?) to remove the Cats if they're clogged up, thaat could be the reason you're not getting it to start..
