Engine Trouble NEED HELP!
 
I was out running my truck and the neck of carb came off and i got a bunch of dirt in the engine what do i have to do to clean it out. can i just spray alot of wd-40 in it and drain it out or do i have to tear down the motor and clean it all out. what do you guys think i should do?

A tear down would be the best thing to do. I got sand in one of my engines and couldnt remove the conrod from the crankshaft so I opened it up as much as I could and flushed it out. I must have flushed about half a liter of fuel through it. I never did get everything out, I could still hear a little grinding. 6 gallons later and it runs great, cant say that will be the case for you though, thats why I say a complete tear down would be the best.

Pull off the cooling head, usually 4 screws, remove backplate and starter. Now you can push the cylinder sleeve up and out. Now remove piston and con rod(sleeve must be out first). OH! Before all that, remove clutch and flywheel and split cone! After removing piston and rod, just push firmly on crankshaft from the end that flywheel goes on and it will slide out the back. Now you can flush/rinse all the crap out from the bearings left in the case, and oil them up. Do the same with other components, and reassemble. Be carefull when removing the head as there are thin shims that are easy to loose or bend. Also when putting the sleeve back in, make sure it is aligned with pin in case. Remember, when putting back together that the piston and rod go in before the sleeve. It is very simple really, just kinda scarey the first time you do it.

The above is all stated very well. I agree. Follow this and you will be well served.

Thanks guys. it was a pain but i did it. its running once again. whats the best way to keep the air filter from falling off again? is there any clamps or anything that would be tighter than a twist tie.

This is what I do, its so solid you can lift the whole truck by the air filter.
