I was driving my Thunder Tiger EB4-S2 today when I noticed some smoke coming from the Clutch and flywheel area and a huge power loss, Upon further inspection I took the body off and saw that my fuel pipe had a small leak directly above it which was causing fuel to leak onto the clutch area. I changed all the fuel lines, turned on the engine and it doesnt repond at all, I give it full throttle and nothing happens, it stays at idle and the flywheel does spin but the clutch doesnt whats wrong.

Just to be clear this is not my fault, I gave it to my lhs yesterday and they probably did this!

dsales, I can't see this being a problem with your clutch mate. If you're giving it full throttle and nothing happens, i.e. engine doesn't rev up, it could be a problem with either your receiver, servo, linkage or most likely the battery.

If your engine does rev up when you give it throttle but the clutch doesn't engage, take the clutch apart and have a look at it. If the shoes are all worn out, you'll need to be changing those out.

Good luck

Thanks for the help tommygun, it was both the throttle linkage and the clutch shoe, clutch shoe was worn and the throttle linkange was loose, just tightened up the hex screw and changed the clutch and its good as new.

While ive made this thread, i will say another problem my buggy has, the fuel tank is allowed to move to make room for the servo to go to full throttle, but when the servo is at full throttle, it pushes the fuel tank back and makes it touch the exhaust which is melting it, is there anything i can do which will stop this, maybe some foil around the fuel tank?

If the end of the linkage that is touching the tank is spare, just cut it off. Or try to reposition the hex nuts in such a fashion that at full throw, they don't touch the tank.

Alternatively, check the throttle limiter on your transmitter. If you give it full throttle, while looking down the carb hole, it should only pull it out far enough to ensure a fully opened carb/throttle hole. Any more and you may burn the throttle servo out prematurely as the signal it's being sent is trying to push the servo further than is physically possible.

That movement you see in the tank is there for a reason, but not to allow the throttle linkage to push it around. It's so that the tank can take the bumps, slams and normal motion and vibration that occur during normal driving / racing.

I can not imagine a car manufacturer spending the time and money on R&D to develop, construct, market and sell ANY type of car that doesn't allow such important functions like throttle / break linkage to move freely and in an un-obstructive fashion.

One more thing you can try if all else fails, use a longer pipe brace to position the pipe a bit further away from the tank.

You'd be surprised... the ofna's I had all did the same thing... the tank was just far enough away from the pipe to not melt(not that I could start the dam things in the first place) but testing the radio as made me come to that conclusion... also broken servo gears because it's quite some load that the tank puts on the servo...

In the manual it tells you to cut the excess off so it doesn't hit the tank.
