Hello everyone
Im new here and new to 1/5 scale buggy's

I've bought a FS racing 1/5 petrol buggy
I've mixed the fuel at 40ml oil to 900ml petrol *tank was not full but would not take any more without having to tilt the buggy* the mix should be 25-1 by the manul
I've then primed the Carb intill there was fuel in the carb bulb + a small air bubble
Choke on my carb is in the *down postion*
I've pulled the starter 3/4 times SLOWLY to allow fuel into the engine *to give it some oil*
I've then pulled the starter 3/4/5 times fast/hard with no engine POP or choke POP * i don't understand that part* *engine not trying to start at all
I've try again to check for fuel Primed + try again to choke pull the starter + unchoke and the engine still would not start

The fuel is afew months old..., It does not smell like varnish

I've taken off the carb to check for the Gasket is the correct why around, I've checked the fuel lines are the correct way around

I've taken out the spark plug and checked for spark *it sparks every pull*
With the spark plug out, The spark plug has ignited some fuel while at the spark plug hole

I've Taken out the spark plug flipped the buggy upside down to check for flooding, + pulled the pull starter *very very small amount of fuel came out*

I've pull the started with the spark plug out to check for fuel spray *there is a very small amount fuel spary coming out of the cyclinder*

Im at a lost at the moment, its read alot of forms about to common problems

I know the problem can be

Bad fuel
Bad spark plug
Air leak


Thanks Sonny

id start with new fuel and spark plug. the spark plug in the cheaper models like fs,rovan,king motor, ect can be off brand clone junk so id get a proper ngk cmr7h plug and some new fuel. hope that fixes ur problem

Hello

if you have read my first post

My fuel is afew months like maybe 6-8 months i used it for a minimotor
I have about 3/4 liters left ina jerry can

when i've had out the spark plug to test for spark, when it was at the spark plug hole for the cyclinder it would ignite the fuel inside the cyclinder... and a good fire ball will come out

At the moment its sat without the spark plug in, hoping its just flooded but i oready ruled that out, but it wouldn't hurt
 
evssv said:
my bad?...yeah as said fresh fuel and a ngk plug.?..but u can still chk for a spark now to rule that out?

I've had the spark plug out several times while in the process of trying to start it...

it sparks every single pull, of course a smaller pull would make it spark less

Easy there sparky . :ROFLMAO: My Rovan came with a NGK.
Do you have a gas lawnmower . It will burn it . Double check your coil gap with a business card or the proper feeler gauge .
 
I've got a feeling that the spark plug just does not work under compresion
When pulling the pull start nothing happens
cannot hear the engine trying to start what so ever
I know its getting fuel, I've had the fuel spray out from the cyclinder when i took out the plug before

And i don't own any gas powered garndening tools
 
I have a new Losi 5T that refused to crank the first time. I finally got it to crank by holding the throttle wide open. If finally started and now it will crank right up.

Good luck.

Whilst your waiting leave the spark plug out, it will definitely be flooded from all the failed attempts to start.
When you do get the new plug start the engine without the choke?

I've also Before messing with the needle settings, just turning out the L needle 1/4 to allow to fuel in,
