I took my jato 3.3 out to the local sand pit, ran a few tanks through it, all of a sudden it wouldn't stay running. So i cleaned it out pretty good there was sand in the air cleaner, in the carburetor, and some on top of the piston. I cleaned it all up removed all the sand, changed the glowplug, and it will not start and it seems like i have no compression. Any Ideas ??? all are welcome thanks

aparently, i'm really not a 3.3 fan no more. i removed the 3.3 in my jato, revo, and 4-tec, and put in more durable engines. i'm finding many problems with them. the 2.5/2.5r are the only long lasting engines. with your problem not starting...check to see if your heat sink is nice and tight on the crank case. see if the fly wheel isnt tight, put in a brand new glow plug. and i think you've destroyed your engine. getting sand throught the carb and into the engine. not the best thing to happen to any motor. if the things i've listed above don't work, and it's still not starting, you probably messed the engine up. (hopefully not)

i got dirt in my engine on accident and i took it all apart, lube it up and it started up and its still working fine after that.

i was running mine on sand once, and it hit something and fliped over and i saw something fall off so i thought it might be the air filter because it always falls off when i flip it over, i saw that it was off and stoped the engine straight away and pulled the pullstart gently and i could feel (and hear) that there was sand in the engine, or at least in the pull start so i took it home, took the engine out and took it apart completely and cleaned it with water intill i couldnt feel any more sand in it when i turned the crankshaft. then i put it back together and tried to start it (to clean the water out of the engine) and once i got it running (it took a while) it worked just like it did before. and there wasnt just a little bit of sand in the engine, it was all on top of the piston, inside the crank case in the groove thing for the con rod to go in and in the bearings. also in your sig you say you have a custom air intake, do you mean a custom air filter? do you think that might have caused your problem or not?

I am sorry guys but if an engine runs with sand on its internals for any length of time, there is no way this engine runs like before after cleaning. Even if the difference is not noticeable in the early days, such an engine will not last long. :(
Proudpapa2005, if it seems like you have no compression, I am afraid this is probably correct. A new piston/sleeve/conrod set could restore performance for a while but the crankshaft and the bearings are also very likely to be damaged. The ultimate remedy would be a new engine.
Donít let your air filter to dry for any moment and clean and lube it as often as you can. Better yet, more often (and more meticulously).;)

If you don't have compression, sorry but the engine is toast. If you were still getting compression you'd want to take it apart and run water all through it and make sure you get all of the sand out, then run WD-40 through it to get ALL of the water out.
