Wet spark plugs

Ok, so my spark plugs keep getting wet with gas. I only get about a crank or two before the get wet again. I was drying them out fully too. Am i getting too much fuel or do i just need new spark plugs?

Pull the fuse and crank the engine with the plugs out to clean out chambers. If plugs are old, buy some new ones and try them. You can trythe old plugs by drying off the trailing plugs, then dry and hit the leading plugs (on the end) with a propane tourch to heat them up and burn off any residue gas, put them in then give it a try. Hopefully you didn't lose compression, but if you find you did, you need to go everything again, plus put fluid into the chamber eg oil, atf.

Congratulations on the correct usage of the word "too".

You're getting flooded and maybe at this point after trying several times it's really bad. Does it sound like it's spinning too fast?

I think you may need to employ the severe flooding techniques. Take the plugs out and the two engine fuses and crank it over 'til all of the excess fuel is expelled. That's the first step.

Thats what i'v been doing, pulling the plugs and drying them off with a torch. And i'v also been unflooding the engine every time i pull the plugs. My problem is that after i unflood it, dry the plugs, put them back in, and start her up i only get about 2-3 cranks before my plugs get wet again. Then i have to do it all over. Should the plugs be getting wet that fast?

BTW: I just rebuilt the engine.

is there a way to set how much gas your injectors let in when you start your car?? I don't think there dirty, Cause i cleaned them when i was doing my rebuild. Its gotta be something else.

If its a fresh rebuild, its going to happen. I probably went through $100 in plugs during my break in period. Rebuilds are very low compression and therefore flood very easily. Do the advanced unflooding, and squirt some oil in for good measure. It will probably happen again, just be patient with it.

A fouled plug is hard to "See". I never figured out just what part of the plug was fouled. I used to race 125s and those things would foul a plug in no time. Put two plugs that have the same hours on them with one fouled and one not you may not be able to tell the difference.


there is the obvious black oily plugs but save that discussion for another day.
