I have a sirio .18 in my tmaxx with bb pipe it did run real good till the air filter come off.
I was running in sand and it stalled so I started it back up and run it some more, well it stalled 3 more times before I checked it and the air filter was gone now it stalls all the time but only when it idles.

I check the piston and sleeve and it looks good.
I changed the plug
I check the carb it looks good

What do I check next?
 
make sure u take the engine COMPLETLY apart and clean it because a grain of sand can mess up the whole engine

I would do what he said. You need to tear that sucker completely apart and rinse it out with fuel/alchohol/whatever. You need to take everything apart including the carb. Clean it piece by piece, lube it, put it back together and see what happens.

Tough luck man.
 
i will be suprised if ur engine will still run. even the finest dig on the piston/ sleeve will screw it up. take a air compressor turned down and blow the whole engine out while its apart. remember to check the bearings, clean them, whatever to make sure there is no dirt in them. then re assemble the engine with ARO(after run oil).

I hit a gopher hole once with the ST, I cut the gophermound in half, and the whole engine was buried with no air filter. Tore it down, it runs fine.

I also put my savage in a creek twice allowing mud insde. A complee tear down and it runs fine again and again.

Just dont run it. Tear it don completely clean it, and you should be good to go. as long as no huge peices got caught between the P/s
