your fuel line needs to be changed .. those lines get clogged up after awhile .. garantee you if you change the fuel line it will work ( about 3 bucks )
I have a revo 3.3 as well, and I change my line atleast once a year.

you can try it but I dont think it will help if it was the fuel line it would not start at all if it did start it would run real lean as it would be sucking air in the the fuel. run it till it stalls and see how much compression it has.

I'm willing to bet it's a worn piston/sleeve. Notro engines becomre real finicky if not impossible to keep tuned when they wear out. Usually, thats the reason why the owners sell them, they get frustrated. Sleeves can wear out fast, in less than half a gallon, if they are run to hot.

I ran it for about 10 mins with no problem, I turned hard and the truck flipped over and stalled. The engine would not start again. I hope I didn't burn up the engine!! If I have to replace the piston and sleeve I'm guessing I'll have to brake the engine in again.

Wondering how long can expect an engine to run before a rebuild and about how much to replace piston and sleeve?

Hot engines are allways hard to start. The fuel vaporizes real easy in a hot engine, and then it doesnt want to ignite. When they stall, you usually have to prime the heck outa them while cranking. Randomly plug the exhaust outlet with your finger while cranking to push fuel into the engine. It'f the dreaded Flame out of racers. watch for the HOT exhaust pipe though/. They sell litle rubber exhaust deflectors made of silicone rubber, they get the erxhaust away from the car more and you dont burn your fingers. The elec start engines are tough to start, try starting a pull start engine when its hot... LOL. Thats why when I was into racing, I most allways had a starter box. They spin the engine at a fast speed. Pretty hard with a Savage though. Also, you can open throttle all the way, crank over a bit, to let cool air into the engine. be hanging on to the car. It may fire and GO.
