Just got an FG Monster Beetle!

[Gamefan]

I bought new spark plugs and still not starting. Not sure what to try now. Should I take the motor apart and go through it piece by piece?

 

[Gamefan]

So my choke only moves a little bit. Could that be the issue? Right now it is down at 6 o'clock. It only moves a little and not to 9 o'clock.

 

[t2boats]

Yep it should sweep through 90° so did you test the spark plug against a metal part? You can rest it so it touches the engine itself with it still plugged in to the ignition lead, pull the chord a few times and look closely you should hopefully see the tiny spark.

 

[t2boats]

Can you post a pic up of the choke at 6 o'clock and to where it travels to.

 

[Gamefan]

Yep give me a moment

 

[t2boats]

with the choke being on all the time it's flooding the combustion chamber, and why you're getting alot of fuel out the top when the plug's not there.

 

[Gamefan]

Here it is at 6 o'clock.

Here is it moved.

 

[Gamefan]

It barely moves. Should I remove the carburetor and then make sure it moves properly? How can I correct this? There was a lot of spewing fuel when I tried to start it without the spark plug.

 

[t2boats]

Yeah that'll be the amount of fuel thrown in by the carbs' choke. Yep, take it off and have a quick shufty yourself, ya never know the problem may come jumping out at ya

 

[t2boats]

Daft question but, it doesn't want to go the other way does it? And how far along the shaft does the black lever go?

 

[Gamefan]

Sweet! Thank you T2Boats! As always, excellent help and advice! I will take it apart tomorrow and make sure it moves 90 degrees and then put it back.

 

[Gamefan]

It does not. It stops after that little movement going toward the front of the car. I know it does not move 90 degrees.

 

[t2boats]

Wondering if perhaps the joint between the carb is filter is restricting its movement, as there's nothing really in the way to prevent it, it's in its own little space.

 

[Gamefan]

I will remove the filter and then see what happens. Since the carb is full of fuel, I cannot remove it this evening. I will have to wait until tomorrow morning when I take it outside. No space in the garage to work on it yet.

 

[t2boats]

At first I thought my choke levers on my RC's sit at 90° to what yours does, but I'm wrong. Just to check the orientation of your pix, you're taking the photo looking down on the engine/carb? Your throttle bar is 180° opposite to mine. The rod actuates my carb levers from below the arm sticking out the carb, yours operates it from the top side of the carb, so that must mean you've had to reverse the servo at some point when setting things up. Anyway, I'm quite interested to see what you find when you pull that carb off!

 

[Gamefan]

I think we got it! I removed the filter and carb. The picture I showed you never really opened the carb, so it was always closed. Now it opens and the movement is a fill 90 degrees. I can literally see it open now to full and close fully.

 

[Gamefan]

As for the servos, I never changed them, since this is an RTR, I so far have charged everything and today tried to start the engine.

 

[t2boats]

At least you know the carbs' choke and throttle butterflies are free to move. When you refit the carb/filter, see if you can see what the gasket is going inbetween them as you offer it up and begin to screw them together.

 

[Gamefan]

I am able to start the engine now. The idle seems weir to me. It is going from low to high over and over. What do I need to adjust?

 

[Gamefan]

When I accelerate it goes no where and then cut off. Sorry for all the questions. Just trying to learn all I can.

Thank you!
