Help, dirt got in my engine
I was out running my RC8 yesterday, all was well for about 2 tanks. Then it started flaming out and I could not get it to stay started. I have an issue with my carb neck (new carb on the way) so I thought this was the problem. Well I just took my air filter off and this is what I found
How much damage can this do? What's the best way of cleaning it? I don't have the tools to take the bearings out.

A good place to start would be to pull the engine apart and look at the piston and sleeve to see if they damaged. You could try cleaning out the bearings and if they still feel smooth they should be alright.
To remove bearing you only need heat and a wooden spoon or dowel.

Please post back with info on how the dirt got in there, or at least how that much of it was able to get in there. I'm just curious and want to learn from it.

I would take it apart and flush it out really well with denatured alcohol. If you see scratches on the liner and/or piston you will probably have to replace those. If you don't want to take the bearings out you could leave them in but be sure to clean them out really well. If do a search on the web I am sure you can find an article on taking the engine apart. It isn't really all that complicated. Before you put it all back together make sure to dry the alcohol out and oil everything up real good with some light oil. Maybe you will get lucky and not have any damage but you can't really tell till yo tear it apart.
edit: I see you beat me to it. Do you see any scratches on the liner?

The engine still has great compression.

From the pics it looks like you might have gotten away with it, but its hard to say. When you put it back together make sure you clean out the air filter and make sure it seals well onto the carby and filter.

That is definitely a good sign.

If your gonna use brake cleaner make sure you avoid getting it on any of the o-rings or other seals. After-run oil is fine to re0oil with, its what i use, but wait untill the engine has dried out before re-oiling

OK, I cleaned it with both plastic safe contact cleaner and denatured alcohol, blasted it real good with my air compressor then lubed the shit out of it with after run oil. Worked it around really good by hand. Everything feels smooth, no grittiness or anything. Keeping my fingers crossed
