Main thing is does it have compression? Should have a definitive "thump" when it turns over. A worn sleeve will loose compression, and they run/start terrible. I have sleeve resozers that can extend the life of the Sleeves, but they are not all that expensive to change. They are a wear item. If oyu run lean, or to hot, it's hard on the sleeves.

The engine does have compression. I pulled the carb and everything seems fine. I put it all back together primed the fuel line and still nothing. This is very frustrating but a good way to learn about the damned thing! Not sure what to do now.

What are you using to start it? pull start or other method?

If the motor is shot I think I have a spare, Traxxas does have a engine replacement plan where you exchange your old for new at reasonable prices.

How are you priming it? They need exhaust pressure to pressurize the fuel tank. The pressure in the fuel tank then pushes the fuel to the carb. Put finger over the end of the exhaust when first starting, to build pressure in the tank. See the hose coming from the exhaust pipe to the tank. Also, that can get pinched,. or cut/worn and you wont presurize. it can take a bit, to get fuel into the engine.

I got it to start! but it still needs work. Turns out the battery in the ezstart wasen't charging properly and couldn't turn over the engine fast enough. Had to charge the battery 3 times to get a good charge. also found a broken engine mount, brake caliper, bent steering arm, missing fuel line clip.....

But I got it to start and it only took me 2 days! How I manage to keep a reef tank is beyond me sometimes.

I know it is obvious but it is worth repeating.

After handling fuels remember to WASH YOUR HANDS THOROUGHLY before you put them into your tank.

RC tining is a tricky thing. When you lean them out to much, they seem to run AWESOME. but thats usualy to lean. Heat is a big enemy of Nitro engines. I try to run mine around 230F at the glow plug. Best tool to get is a little InfraRed Temp gun. Point it at the top of the glow plug, so it reads its temp. Need to allways tuneit.Weather conditions, temperature, Humidity, all effect these engines. Even throughout the day, can change its tune. Get used to tuning, and it will be easy

Hehehe, wait until you hit something with it and count the broken parts

I'd swear almost every time I take my truck out it's at least 20-30$. Last time I caught the front right tire on a big enough tree; broke the upper and lower a-arms, bent the dog bone, and broke the steer servo saver

The problem is for every part you break, there is an 'upgraded' better part that always costs more

damn these expensive hobbies.....
