mud in the engine?
 

Planted my OS .15LA in the mud. No damage just have to clean it up.

I did not turn it over, I removed the engine, took off the muffler and carb and dropped it in a tub of fuel.

I did see dirt when I took the carb off. should I disassemble more? what next?

Openning it or not is up to you:

Take it all apart, including the carb and first clean it with soapy water, rince and then go with the glow fuel soak. The later will remove the water that remains. Make sure you get the ports in the carb clean also. I've got a couple ultrasonic cleaners that just do wonders for getting the curd out of the tight spots. Ikeep it low on fluid and use some big mouth jars, like salsa comes in, and put the parts and glow fuel in the jar, then suspend the jar in the USfluid. The glass will transfer close to 100%of the enegery through the jar into the glow fuel and contain all of the crud the washes loose. I wouldn't suggest buying a US for just this, but if you are going to be flying a lot, sooner or later it time for new bearings and a good cleaning even without the mud baths and the USis a great addition. I pulled the regulator apart on an O.S120 SII yesterday. the screen was really loaded. I rinsed it with denatured acohol, still not looking good. I used a brush and got a bit more off it. I finally put a half oz of glow fuel in one of the little cups I use for epoxy and droped the screen and hit it for about 15 seconds in the US and it came out looking like new.

I know you just pasted the link.....but that is just waay overkill.....a Hairdryer!!
Steve, once the carb is removed and everything soaking you can see if any dirt went into the intake on the crankshaft, which likely didnt happen,, I would remove the backplate to check, but I doubt you'll find anything....pull the head or at least the plug,,and turn the engine over ((under fuel (soaking)) slowly....dont get squirted by the fuel!!!!!... put it back together oil it up and fix that model, its finally getting warm out!!!...you did good.....Rog

Lastly, CP uses a mason jar,fill it with fuel, alcohol, almost anything, and duct tape it to an orbital sander (this is a poor mans ultrasonic cleaner) stick it in the vise and go walk the dog

Mud in your engine? Is that the same thing as "mud in your tire"? ("My Cousin Vinnie") :D

RE: mud in the engine?
 

AH!!!! what a movie

RE: mud in the engine?
 

It probably works just a well also. I'm not sure I would leave the room with it running though, or for that matter Iwouldn't bother to tape it down, just hold it to the rubber pad for a short time. It doesn't take much to get the dirt mobile again.

Camp,,CP's been around a while and comes up with all kinds of stuff....made a foam wing cutter out of a stick of wood, a light dimmer, a banjo string, and a battery charger!!......if it was me and the engine hit the mud that day, I would pull the carb, backplate,glowplug, and stick it in a jar of rubbing alcohol (way cheaper than fuel) and shake the stink out of it for 5 minutes and turn the crank over under running hot water (well I might pull the head, but I didnt when it happened to me) going into the cylinder,,,,I just revived a bunch of old .049's by setting them in a quart of rubbing alcohol...engines are dirty anyway, ....then oil it all down/up inside and out and run it as soon as possible.....Rog

I like to hose the whole mess off outside and take a stiff bristle brush to get the grass out of all the nooks and crannies....then proceed inside to the kitchen sink.
These OS LA engines break down like a nicely fitted handgun.
I've broken a couple crankcases...a hairline crack developes from the backplate forward past the mounting lug.

[Rog..I'm too cheap to use a battery charger, I use 120 volts through a $7 light dimmer.] [8D]

RE: mud in the engine?
 

That is a lucid, intelligent, well thought-out objection. Overruled.

(Sorry...just could NOT help it.)

From the referred article:
"Warm soap and water may also be used, but each piece must be dried with the hair dryer as it is cleaned to prevent surface rust. Do not use alcohol as it attracts water and can form surface rust before the piece can be dried."[sm=bananahead.gif]
Besides, you should take a shower after you finish the cleaning:)

"These two yutes..." A definite classic.

As for the mud, it has happened to me and I kind of take it on a case by case basis. Sometimes the mud ingestion seems to be superficial so a good spraying out with an aerosol cleaner gets it done. Other times I've seen it more serious and it is better to play it safe and disassemble to engine.

RE: mud in the engine?
 

If you are a crappy flier and can't hit the runway in a month of Sundays, a can of brake cleaner goes a long ways in doing a quick field cleaning of an engine. Just stay downwind of everybody when spraying.

RE: mud in the engine?
 

Yeah sorry, I only got to page 2 when I gave up bothering with that article......I face planted an OS .40LA and .15LA, cleaned them as stated and they are both fine...If I drove my motorcycle into the ocean by accident, I would have a little more concern,,Steve took what I (no pic of the engine) consider common sense moves to save/clean his engine...and I did state to oil it all up and run asap...Rog

Have you been watching me fly or something?:D

Everytime I see the title "MUD IN THE MOTOR", I start hearing it sung to the music of ....

Smoke on the water !!!!

RE: mud in the engine?
 

Take your engine to pieces and drop every thing in a tub of petrol, let it soak in for a while and then clean piece by piece with a fine tooth brush or paint brush untill you have it back in good clean condition and then put it back together.

RE: mud in the engine?
 

This is what I would do. It would nag me to think there might be something in there that I missed. 2 Strokes are easy to break down and put back together.

RE: mud in the engine?
 

HI THIS is my procedure Works great for years for two stroke glo-pull the back plate and the head dirt only gets up to the head sometimes-back flush the engine from the back plate-slowly turning the engine-be sure the crank is open to the carb to allow the water to flush the carb-with a flash light and Q-tips get EVER speck of dirt out of the crankcase and the piston and sleeve -spray down with WD-40- do the above again-check all for specks of dirt again -the wd-40 will oil the engine and absorb any moisture one speck of dirt will do damage to an ABC engine-ringed engines will handle a speck betterput it back together and you are ready to run it - no need to use fuel the stuff is expensive ENJOY REGARDS TONY

RE: mud in the engine?
 

I can probably have that engine tore down cleaned and runing within 40 minutes. Easy peasy lemon squeezy of an engine to take apart.

If the liner isnt glued in with castor that is, then give me 45 minutes . http://www.rcuniverse.com/forum/js/f...wink_smile.gif
