Ten Tips to Get That Engine Running

Ten Tips to Get That Engine Running

Nitro engines aren’t a plug and play deal like brushless power and because of that, time needs to be spent tuning and trouble shooting them in order to enjoy your time with them. These engines are very simple machines and don’t require much to run. If it’s getting air, fuel and spark, the engine will fire. But things don’t always go smoothly and there will be times where you have to figure out what the engine is asking for in order for it to run correctly. These 10 tips are here to help you end the frustration and start up ...

  1. ENGINE WON’T TURN OVER : could also be caused by the piston being stuck top dead center (often on brand new engine), usally fixed by turning the flywheel with a flathead screwdriver which will move the piston. If piston is stuck horribly you can remove the glow plug first.

    Thanks for the tips Kevin!!!

    1. i just got a new red cat shockwave
      and it cranks over until i put the glow plug igniter on then it sticks. when i pull the igniter off it starts to crank over again
      what should i do

  2. I HAVE A NEW DYNIMITE .21 NITRO MOTOR IT IS NEW AND STICKS AT TDC I CAN’T TURN IT OVER EVEN WITH THE PLUG OUT, ON MY STARTER BOX, IT WILL BARELLY TURN OVER PAST TDC WITH A SCREW DRIVER AGAINST THE FLYWHEEL.

    1. try a thicker gasket, is there one? you are mechanically hitting tdc , it wont wear off.

  3. Try taking off the heat sink head and pull out the piston sleeve then put a few drops of oil on it and in the chamber then slowly pull it over.

    1. gee, you could pull the glow plug and drop oil in.

  4. The same thing happened to my Baja 33cc

  5. i have an older t maxx. It had been sitting in the garage for about 3 years or so up on the shelf. the other day i had the bug to get it going again. i cleaned out the fuel tank, put in a new glow plug made sure the engine would spin freely. i ran the electric start for about 3 minutes before it started up. after it started up it ran (rather sluggish) around the yard for about 2 minutes. It died on me and now i can`t get it to fire. The motor turns over with the electric start but will not fire. i can hear the compression with the electric start turning. I removed the fuel line from carb and pushed the primer on the tank a few times to make sure fuel was flowing and it was. i tried adjusting the carb with no luck. i`m stumped!!

    1. I have the same problem…..i have to tap the electric start over and over and then it gets some compression up, then it will fire after probably 5 min……glad to hear someone else is having this problem…not glad for your frustrations of course but now we can work together!!

      1. could be poor seal compression cause it went lean and scored piston. you’ll only get fuel seal cold.
        turning over for several minutes means either bad glow battery or plug, you are relying on catalytic compression to get it started.

  6. when I remove my glow the engine stop why

    1. not hot enough on its own, better nitro or lean it.

  7. i trying fire up my .15 motor won’t i put nirto in carb it not make try start but smell burn fums but no fire up how many turn needle supposed be?

    1. start better richer than leaner, then adjust. try screw flush with housing.

  8. Hi there I have a nitro car dirt car and it wont start can u help me ?

  9. MY CAR WAS RUNNING FINE THEN I TURNED IT OFF NOW EVERY TIME I PUT THE BUMP STARTER IN AND TRY TO START IT IT MAKES NO SOUND OR NO TRY TO START WHAT MAY THIS BE

    1. Addam, you’ve got mail! 🙂

    2. my new car dragged the clutch nut, it over heated and destroyed itself, would not turn over, check the nut, it is like a ratchet, turns motor one way, spins free other. if you are unlucky, it will be inside the motor, lucky outside between starter and back plate. $10 ebay.

  10. you forget a broken con rod, wouldnt turn over, broke the pull start. made my own. can’t beat electric starters, they start any motor, unless you had the head off and might have got it cocked and loses compression. it’s too easy to do. i’ve skinned my fingers yanking on the damn pull starters.
    if you die when you take the glow starter off, its not running hot enough, lean it. or higher nitro, or wrong temp glow plug for your fuel.

  11. adam, what about the clutch nut? had one go, no turn over.

  12. Hi there me and a friend recently bought a sledgehammer s50 each and there being a complete pig to set up. Does anyone know they basic needle settings, and ill go from there.

    1. Not sure where to start with that one Baz but the best place to start is probably with a call to Thunder Tiger.

  13. Hey I bought a 1/8 scale gas nitro rc not long ago. I broke it in right now after running a few more times the front drive shaft broke. I don’t no how it did cause I didn’t run it hard at all. While I fixed that I put a electronic starter on it. Now try 2 work with me I don’t no the names of the parts. Anyway when I put the new starter on it wouldn’t turn so I took the top of the engine where the glow plug goes off. The big piece on the top notch the flat plate that the glow plug sits in was still on but not screwed in so I tried the starter again next it turned but the plate pushed up now the cylinder inside came up but not out.I pushed it all back down now put it back together. I couldn’t get the car 2 start. So I took most of the engine apart from the top down and towards the starter. I didn’t mess with the clutch area. I cleaned and oiled it now got the car to start. It didn’t have the power it should. I looked at the clutch shoes not a spring was broken. I put it in the shop now they fixed it. They couldn’t get the Power right. I don’t no what all they really did but I hope you can give me some advice on what the problem might be. thank you for your time sincerely Mike Norris

  14. i also have a 1983 gold edition thunder tiger silver fox car, works great but does anyone know where to find vintage parts for it
    other than ebay/kijiji.
