Hi All!!

I am a newbie in RC world. I got a new GS Racing "Storm" Truck. I am in Andaman islands. Readymade fuel is not available here and nitro methane is also not available. Can I run the engine on Methanol & Castor oil only? May be in the ratio of 85% & 15%? Please advice!!

The engine should start and run without nitro.  But you may have performance issues in terms of racing speeds, and also possible issues with a smooth idle.

Among the RC crowd I have seen, it is the car folks who always thirsty for high nitro content (always 30% or higher).  I have had car folks come to me to exchange their regular CoolPower 30% fuel with my Cool Power "low smoke" heli 30% blend, because they were sometimes not able to see their cars in the smoke (a heli in the air would not have that problem).

People tend to use various percentages of castor, 18% is a common number when no nitro is used.

Thank u so much Anwar for ur guidance. I tried 85% methanol & 15% castor oil. But my engine wont start!! Any dieas what I should do next? I checked fuel lines...the fuel is entering the carb. I doubt the blow igniter. I think its battery may b weak!!

Please refer to this thread...  I am sorry that it is a bit long, but it covers all the things you need to check.

On a quick note, you need to check the glow plug (take it out and see if it glows with the ignitor, it could be the plug, or the ignitor charge), needle settings, throttle trim (1mm to 1.5mm open initially).  There are a bunch of other factors. Check for leaks, see if it starts by momentarily closing the muffler/exhaust (this pushes fuel into the carb due to pressure build up, but do not over do it), and so on and so forth.

Thank you onc eagain anwar for your reply and guidance. I hope with all ur help i'll be able to start it 2moro.

leave andmaan

Sorry Buddy!! Can't!! Born n brought up here. Beautiful place. Can't leave it just cos of a RC Car!!!!

Plus, many (or is it most?) other parts of India are just the same when it comes to nitro availability !

just joking man heads of       love  ur place  ,good answer

am also just kidding man!! anyways anwar I was unable to start the engine 2day also!! bad luck!! the glow igniter is fine...checked. fuel line is ok...checked & saw fuel coming into the carb. there r 2 screws(needle) for adjustment. a big one is just near the fuel entry point into the carb. the manual says factory standard is 2 and 1/2 turn anti clockwise from fully closed. i set it at that and another smaller screw below that, std adj is 0.8mm. i didnt adjust it!! my fuel is same...methanol 85% & castor oil 15%. any more suggestions?

Did you check how much of the barrel is open ?

by Barrel u mean what exactly? i removed the air filter pipe and took a peek inside the carb, then tried pulling the throttle in my remote. there was a barrel/piston kind if thing moving inside the carb and when i left the throttle it came back and there was a small gap i could c.may b 0.5 to 1mm.

You will see the barrel moving/rotating inside when you remove the air filter. As you open throttle, the air intake hole will grow in size.  There should be a close to 1.5mm opening initially.  You can try to start at a little bit more open throttle position.

In terms of other items to check, just follow the thread I mentioned above.  If anything mentioned there is not clear, please let us know.

Can you also post the model number of the engine and carb ?  Or post a picture of the carb ?  There are 3 different items to be tweaked on most engines... the low needle, the high needle and the idle set screw.

To see if it is fuel issues, you can drop a few drops of fuel into the carb barrel opening and see if it fires into life (but will die soon when the fuel runs out).

Anwar do u mean....drop a few drops of fuel into the carb barrel opening after removing the air filter...and then giving the engine a kick?

Yes. But a small quantity (few drops), so as to not flood the engine.

ok will try n get back to u

You should post some pictures of your engine too, in addition to trying the steps in the thread mentioned earlier.

Pictures allow us to ensure that your setup looks ok (like the muffler feedback line is connected and so on).

What kind of a starter are you using ? 

anwar pls ref following images. tried opening the throttle and letting in a few drops of fuel and then pulling the starting cord with the glow igniter attached to glow plug. but i couldnt c any fuel firing!! is the procedure followed by me correct? can u guide me reg the same with the pictures reference?
                  OVERALL VIEW


                   SCREW 1 GOLDEN COLOR?


                      SCREW 2?


                      SCREW 3?


                       Normal Throttle...Not touching remote control!!  Is this the barrel u r talkin abt?


                       Half Open


                       Full Open

anwar sir you both can use skype it will help better and  its free

i think it would b better if anwar sir comes to port blair!! 

ya   wow

I am waiting for people like Ajo to look at the pictures and comment on car specifics.

ok sir will wait

BTW, you have correctly identified the barrel opening. It needs to be around 1.5mm open when you start.

In a quick inspection, the connections etc look good.

iam basically a marine engineer n work on large diesel engines in ships. but this tiny lil engine is getting on my nerves!! i know its quite simple but it wont start n i dont want to fiddle with the screws much
