Default Kyosho Rampage GP-10





Hi,
So I found this RC at my job and decided to restore it.
After some research online I figured it out that this is a Kyosho Rampage GP-10 from late 1980's,
if it is not please correct me.
I'm new to the RC world and obviously I will need some help to fix it and that is why I'm here
The only mechanical experience that I have is from fixing my scooter/vespa??!.
The front tires, the rubber is dry and cracking, the rear tires are in good condition.
The remote control doesn't look like that it is working and I don't know if the servos are in good shape also.
Battery holder is nasty and i found a cheap one online that I'm going to order.
On/off switch is full of rust will have to replace it.
Air Filter and Body are missing.
The engine was stuck and the pull start was broken and also stuck.
I have cleaned and lubed the engine and all the other parts and it looks like that everything is good.
I purchase a beginners kit that included a glow plug igniter, tested the glow plug and it looks good.
I'm waiting for a new pull start that I have purchased to test the engine.
After engine is tested and it is working I will proceed for the rest of the restoration if the engine does
not work, or I'm not able to put it working, this project will stop there

Here are some pictures of how this is going





Does anybody have an idea how to remove these stains?




Cracked front tire.










Head of the cylinder has 1x small crack.




1st part of the starter assembly arrived today. I'm replacing all the parts for the starter.

Default It runs :)

Here are the rest of the parts of the set of starter assembly









I wanted to try it to see if the engine would start and after a few pulls and with some fuel on the piston
the engine fired up for a couple of seconds and just died again.
I didn't screw correctly the part that is highlighted on the image below, that unscrewed by itself and the engine shut off.
That is already screwed in tight now
The hoses for the fuel deposit were loose on the ends, I had to cut them a little bit so they could get stuck on the connections. Also missing
the hose the connects to the exhaust.
When I have the new hoses I'll give it another go.

Need some help here.
So, I pump some gas into the carburetor I pull the pull start and the engine turns on.
The engine will shut off after it takes all the gas from the carburetor.
If I pump again it will turn on, but again it is until it drains the gas that is in the carburetor.
Any ideas of what this could be?

Engine was dripping some old brown fuel from the crankshaft spot.
When I cleaned up the engine I wasn't able to take the crankshaft out so I decided to take engine and carburetor apart again and left them
submerse with nitro fuel inside a small jar for one day.
Now I was able to take the crankshaft apart and clean up the rest of the engine.
Engine is already assembled and I'm going to try it out tomorrow.
I also removed the stains from the frame. (Check pictures).

After

Looking good for sure! As far as the gas problem, make sure there's no air leaks at all from the fuel tank, through the tubing and into the carb. If there is a fuel leak it won't pull from the tank. Verify the o-rings, fuel tubing, carb seal, etc.

Thanks for the feedbacks,
Air leaks should be the issue. The engine works for sure.
I got new tubing and tested out the car after the engine clean up.
It worked for a couple of seconds and went off again.
At least is not leaking from the crankshaft area no more.
The carburetor is little bit bent, and I don't know if that is what is causing the issue.
I'm also thinking it could be the fuel tank.
I've made a deal for a similar car that is missing a lot of parts, but engine is complete with the carburetor and with a similar fuel tank.
Hopefully they are good.
Will update when the parts arrive.

The parts have arrived, tried the fuel tank first and that was it.
Now it stays on, but I have to tweak the carburetor, sounds like it is on high RPMs on idle.
Also got the servo tester and looks like the servos are working good

Yes, they are expensive.
I can only find 1 auction for the original front tires, $24 + $19 shipping from Spain.
For the first runs I'm about to get some cheap off brand tires, then to sit on the shelve maybe I'll get the original ones
