Hello All,

I'm a new 2nd gen owner (1st time with a rotary). I've experienced and read the articles on flooding/unflooding and have a few questions which I hope you could answer for me.

I've had the car for 2 months now with the same plugs that came with the car.

1) Is it time to change the probably fouled plugs since I've had to "unflood" (fuse pull technique) 3-5 times already?
2) I make sure to avoid the "short start", non-warmup scenario (drive at least 30 mins before turning engine off), and still experience flooding the next morning (probably floods once every 2-3 days ). Is this most likely related to the fouled plugs?
3) Would any ignition kits such as a MSD or a Jacobs, help with the frequency or help prevent the flooding condition?

Thanks in advance,
Jay

 

1 Change the plugs anyway they are probably older than you want to have in the car.

2 5minutes of running is sufficient for my car and two others so I don't see why more htan 5 minutes should be the norm for warm engine. If you get flooding anyways the next day start looking at your fuel injectors to be he problem. They could be sticking or leaking fuel over night making it flood. This could only be hurting it more with fouled plugs.
3 I would suppose that more spark would help but this is just on oppinion not facts because if the plugs are already soaked they probably won't fire well or at all.

PS- I would get a cut off switch and look at cruzing performance or RC engineering type of places to have your injectors cleaned proffesionally. If the problem still persists then you probably have compression problems.

 

As you may have noted when you searched under Flooding, many folks claim the plugs should be changed. I never quite understood the necessity for that. Fouling occurs when the plug tip becomes so saturated that a spark is shorted or or drowned ineffective. In that case they should be removed and dried/cleaned before the unflooding procedure is done. However, if the unflood procedure is effective without removing and drying then the plugs are obviously dried by the combustion. There is some merit in removing and cleaning the plug tip if you want right temp and removal of carbon ash.

Now, should you replace with new plugs? Since you have had it 2 months and prolly don't know when they were changed last do the car a favor and do it. Check the plug wires while you are at it.

 

Thanks for all the info.

I've been planning to change the plugs regardless, but before I go the injector route, I'd like to do a compression test (might as well anyway, the plugs are out).

Does anyone have what the compression #'s should be?

Thanks again,
Jay
