Hey, I think I flooded my 7... how do i safetly deflood her?
and if that doesn't work? How do I do a compression check? i know to pull the plugs, but do i pull them all out or can i just pull the front rotor plugs and then the rear? Thanks,
Tim

Pull all of the plugs out, then turn the motor over for a bit to get the excess gas out. Replace the plugs and dump a couple of ounces of MMO down the carb and start her up. This is the simplified version, but has worked for me in the past. After you get her running, change your oil because it will be contaminated with gas (not good).

I have found that 20w-50 oil works better than the MMO. The oil is thicker and builds compression better.

To check the compression using a standard comp. tester: install it on the leading plug (bottom), make sure the ignition system is disconnected, either remove the schrader valve from the comp. tester or clamp the pressure release valve open (I use a small pair of vice grips for this), then turn the engine over with the starter while watching the bounces of the gauges needle. Three steady bounces above 90 is what you are looking for. Uneven bounces or all bounces below 90 spells trouble. you have to watch closesly because the bounces are fast. Do this for both the front and rear rotor.

Good Luck.

I don't think I ever flooded my SA very badly. When I first got it I didn't know that when the engine is warm do *not* pull the choke when starting it or it can/will flood.

Anyway I've had luck with the following two methods:

Method A)
0) Make sure you're in neutral.
1) Push the choke in all the way.
2) Push the gas pedal all the way to the floor and try to start the car.
3) If/When the engine starts take your foot off the gas right away.

This method works by allowing as much air into the chambers as possible .

Method B)
0) Turn the key to 'off'.
1) Pull out the fuse that supplies power to the fuel pump. This is a 20 Amp fuse. It is in slot number 10. When you take this fuse out and turn the key to 'on' (but not start) you won't be able to hear the fuel pump "clicking" near the rear driver's side wheel.
2) Turn the key to start the car for about 5 seconds. It shouldn't start.
3) You might want to wait 10-20 seconds and do step 2 again. The reason for waiting is to avoid overheating your starter motor.
4) Now turn the key back to 'off'.
5) Replace the fuse.
6) Try starting like normal.

This works by keeping fuel out of the chambers while the engine cranks to push the fuel out.

I've never had to take the spark plugs out but I've heard of people doing that. If you do that try to put some rags in the engine compartment to soak up the fuel.

just crank it over as you poor tablespoons of 2 stroke oil down the carb. If it's really bad that's the only thing that'll work with out pulling it.

well, i might be too late... now the engine wont turn over(like its stuck) I duno what to do, i think what i did was i supper flooded it and it displaced all the oil and made an Apex Seal Stick... What Do I Do? Smelled the dipstick and smelled like alota gas...

If you want a VALID compression test, you don't want to put anything in the motor (oil, MMO, etc.)
