I've tried , searched, and tried. My car is flooded and won't start. Old school 4 port 13b with holley carb. I have pulled the plugs and cranked the engine over, put the plugs back in and it still wont start. I tried to compression start it on a hill.

What should I keep doing?

What has worked for you?

Is it trying to fire at all? If it's that hard to start I'd check compression while you have the plugs out if you have a gauge. A cheap piston engine gauge works just fine, hold the relief button down and anything above 80-90psi is good enough, 100-120psi is great, watch for any big difference between rotor faces too.

If you don't have one already an on/off switch for the fuel pump is a great thing to have, and you should never flood it again. I turn off the pump a few seconds before I shut off the car, and dont turn it on until after it starts. Sometimes I'll shut off the pump and let the bowls empty for a cheap/lazy turbo timer

Pull the plugs, turn off the fuel pump, pour some oil down the carb and crank for about 10seconds. Put the plugs back in, maybe a bit more oil down the carb and it should fire right up.

 

First of all, confirm that you still have spark at the plugs. If you do, then pour an ounce or so of Seafoam down the carb and try again. Oil or ATF will work too, but that has a high potential to foul your plugs, while the Seafoam actually cleans them off for you. Works like a charm 99% of the time...

I pulled each of the trailing wires and they have spark. I tried starting fluid too, but that didn't do it. I will try a little seafoam and let you know.

Pull the plugs, spray with brake cleaner, blow dry. Wet plugs will not arc across the electrodes. Juice bypasses them through the wet fuel. Starter fluid strips the oil film from the housings and apex seals thereby reducing compression making the engine even harder to start.

 

Also, is your timing on?

 

I almost got it started yesterday. I put some seaform down the secondaries and spun the engine for a bit. I pulled the plugs spun the engine for a while . Then I put new autolite 2526 plugs in and tried to start it. It was gettng some combustion but not enough to stat it. Gave it two pumps of gas on the accelerator, some combution but not enough... Doing it again today.

 

I finally got it started.
I used starting fluid about 5 different starting attemps with out any combustion. Then there was a little bit of fire for another 5 tries that put some heat in the engine. I sprayed starting fluid one more time, gave the engine 4 little bumps to the get the fluid vapors in all the rotor chambers, two pumps on the holley carb. Gasoline either seafom and oil smoke for a minute before it cleared up.
Runs like a champ!!!

 

I tried Autolite plugs the first time I ever gave my car a tuneup. Ran like crap until I replaced them with NGKs. Never again....
