sucking water.... need some thoughts

[timsyfz]

Here is my predicament. We went out for a really good ride yesterday, but we ran into a little snag. We had to cross a few puddles, and naturally we got a little wet.. After about 6 miles or so my sons Blaster started to have issues idling when we would stop, and then just suddenly stalled out..

We investigated quickly to find that his air cleaner nut vibrated off, and he had some water in his carb. Since then we have had a hard time kick starting it, and when we finally would kick it started it was weak sounding until you throttled it, and once we got it running it ran strong. Once we would stop he would fight to keep it idling until we turned the idle screw up a few turns.

My biggest concern of course is if he wiped out the compression in the motor.. My second concern although not as serious is maybe he just sucked some dirt in his carb, and a good cleaning would help us out.

We looked at the spark plug, and it looked normal, and the way it ran after this seemed to have a decent power still, but I haven't had the time to look at it yet.

I am just hoping for a bit of direction of where I should look for issues...

Tomorrows plan: Take off, and clean carb. I will also be putting a compression test on it (whats the compression suppose to be on these?)

Thanks
Tim

yes go through carb first, and then take the reeds out and check them for damage and dirt also, then compression should be over 100 psi, 120 - 150 psi is about normal, but anything under 100 you need top end rebuild, if it took water into the engine then its probally sitting in the bottom end, i would also drain tranny oil and replace, it takes .74 quarts (3/4 quart)! Hope this helps!

i personally dont think water would blow it up unless u tried to run it while it was submerged..what didnt burn off is probably in bottom end or condensed in the carb bowl..like a dumbass i have no airbox lid and i was washing mine all up till i realized that i had no lid and looked into only see about 6 inches of water in my filter box i had to pull it to get it to start it ran like sh*t for about a few days now it runs like it use too..

u shouldnt have to drain the trans fluid, the bottom crank area is sealed off from the tranny area, if u have water in ur trans case, u have bad crank seals

you may want to pull off your flywheel cover too. Sometimes water will get into there and cause problems

I would think you sucked in dirt with your water. Dosnt take much to plug the idle circuit. We all know how well you can adjust the stock air idle screw

Well yesterday I took the carb off... Cleaned it, and proceeded to take the reed cage off, and low-and-behold I found the lost air filter nut. Also I found anothe rnut, and a bolt from the air box lid in the reed cage.. The reeds were a little beat up, but not too bad however I went over to the other engine that came with this quad, and found a prize ! ! In that top end I found another reed cage... It was a Vforce cage with Carbon fiber reeds... Hmm I thought I may as well slap these in there. Well the beast still has trouble starting, but once she fires she sounds throatier, and has alot more snap... I still need to check the compression, and try to figure out why she starts so hard since she never did before the incident.


Thanks for the input guys.. I will keep troubleshooting.

Oh, and now the things idles wonderfully ! ! !

man, i wish i could randomly find some v-force reeds. lol

Well after alot of clean-up I am pleased to say that apparently he did not damage the motor. The thing starts on 1st kick as it used to, it has th epower as always, and the compression is still good.

Thanks for all the input, and all the help. I am pleased that all that came out of this deal is finding those new reeds, and I got to spend some quality time with his carburetor.
