It is rovan 36. It did suck in some dust/dirt. I ordered a new complete 2 ring top end and a single ring piston and ring....if it the correct size I will have a kit small enough to do comp test on these motors tonight....we have a few of them and my oldest son is experimenting with building his own with porting and polishing and so on..... his first build the skirt cracked on the Piston he's currently running his second building it's running very strongi would go through everything. tank breather ok? servos moving normally, adjusted properly? air leak somewhere? air leak on lines? air filter clogged? gaskets ok? the plugs ngk not no name brand? motor suck in dust from anywhere? (this will have eaten your piston and cylinder) try running with the choke on? nice consistent white/blue spark? head clogged with grass and overheated and died? both carbs don't have leaks on the throttle shaft? the hpi baja motor manual is a must have. it's not the oil that did it, that's good oil, and smokeless still smokes in my expierence. if you do everything you can think of (and you know what you're talking about if you have snap on tools and racing engines) and no improvement i'd start thinking about a new piston and cylinder. i've had several top ends go on me for whatever reason. 36cc, is it a rovan? welcome to the world of gas engines, is why i run electric now. gas is cooler, but has extra 10 systems that can go wrong and are hard to diagnose lol.
