Two things, first after winching out of a swamp I tryed to use my front brakes and they were soft. I pumped them and they get firm and work. I don't think they are full of mud but maybe? Or do they just need adjusting, or new brakes? Before I went and rode they were fine then all the sudden this happend. The other thing is what is my spark plug gap supposed to me.

Dont know about the spark plug gap, but your brakes probably have mud and water in them. Honda's drums are notorious for leaking and allowing water and mud to infiltrate. You probably need to give them a thorough cleaning and reseal the drum. Or, if you have the money, Xtreme ATV Products makes are wonderful front disc conversion kit. I use these, and let me tell ya, even with the pads completely shot, they still stop.

Thanks, any tips on this little job? Just get the drum off and clean it out real good? What about resealing it, just stick it back on? Thanks though, I'm glad nothing is tore up.

Jack up the front, check the wheel bearing. (If that's bad, you're wasting your time with the brakes until that's fixed). Grab the tire at the 12 o'clock and 6 o'clock position and attempt to tilt it in and out. Stick your head around towards the front, and watch the outer CV joint cup. If it wiggles like it's loose, and you think that tightening the big nut in the center of the wheel would snug it up, don't. That is a bad wheel bearing.
If that's good, knock the wheel off, find two 8mm bolts that hold the drum on, and then that comes off.
Clean inside of it, taking care that the O ring (squished into a not very O shape) is in good condition. If there's rust or crud around path where the shoes rub, clean it with fine sandpaper (220 ish), but do it lightly. You really don't want to take off a layer, just what's on top of the metal. Clean the shoes well, and if they're not that great, some very light attention with the same sandpaper helps them a great deal as well. I don't believe that there's asbesdos in them at all, but I still would avoid the dust. There are two wheel cylinders, one for each shoe. One end of each has an adjuster wheel, and an arrow cast into the assembly to indicate what direction tightens the shoe against the drum. This would be the time to familiarize yourself with it. Before reinstalling the drum, pack the groove between the seal lips, but be sure none gets to the inside of the brake drum. Then install the drum. Remove the red rubber plug, and roll the drum around until you find the first adjuster. Adjust the shoe outward using a screwdriver (follow the arrow) until the shoe just causes drag. Tip- You can't really tell over the drag caused by the differential, so if you use the 3/8 inch or so "slop" where the drum will move freely forward and back, it's easier to tell). Once you just barely feel drag, back up (against the arrow) one click. Then go to the other adjuster and set that one. Then go to the other wheel and do the whole thing over again. It can be a bit trying until you get the hang of getting just the right adjustment on each shoe. If by chance you find the instructions from an owners manual or service manual, it'll pretty much say the same thing, except for the counting of clicks. They say tighten until you feel resistance then back up three clicks. Maybe (possibly) when it was showroom new, but won't work after it isn't new. With new shoes and drums you still won't get any brakes that way.

Sorry, forgot the last question.
.030 to .040 inch is the spec. Anywhere in the range is fine, but if you're fussy shoot for .032 to .035 inches.

Check the link in my post above. High lifter also makes a conversion for both front and rear. Xtreme products *should* have one shortly.
