Gopi,
nothing wrong with ur menthnol, but ur 15% castroil needs to be 18 to 20 %. Just make sure ur throttle is not totally at idle, the barrel should be 1/4 open, and try again. There is just some very minor thing that u r overlooking. thats all.
Anwar - i have not touched nitro in last 40 years of modelling, be it planes, heli. cars, boats,  and have not found any engine give trouble. Even my Saito 100 4 stroke behaves on just methnol and castor oil. It is always the human factor. Send me a engine that does not start, and i will  make it start.
I have seen guys struggle with os 46, 75, 91 on the field for hours. without fail it took me precisely a minute to bring it to life. I always say, if u having trouble starting OS engines, the troube is with the humanbieng, not the engine, lol.
Ramesh.

Ramesh i agree. there is something iam missing. wat frustrates me more is that this engine being so simple in construction is getting on my nerves!! anyways i will try with a 80% 20% mix today with 1/4th throttle open. any ideas where i can get a glow plug for this engine....my engine is GS Racing R25MT.

any more suggestions in needle settings? i found 2 screws that can b adjusted.

Gopi,
can u send me images of the carb, taken from left and right side, and as close as u can get without going out of focus. i want to see ur needles, main and idle. I am in delhi and u appear to at Pt Blair, we could video conference of try and solve by pics hopefully, i also want a pic of how much carb u r opening for a start. also give me a link from where i can download the manual for the engine.
Ramesh

rameshji i have posted both the screw pics in 1st page. pls check

remeshji only images screw 1 & screw 2 r correct. screw 3 is not for adjustment i put it up i mistake. its is a screw n nut for clamping the engne block.

OK great, saw that, now i need the manual link on the net, or u scan it and send to rameshtahlan@yahoo.co.in
and by the way, i have sorted out starting and tuning problem from delhi, to guys on the field at allahabad (Vibhu) and Pune (Vivek) for 2 and 4 stroke, hahaha, its unimaginable.  but dont worry, nothing is impossible. Now give me the manual.
Ramesh

Gopi,
do u use skype we can talk live, but need manual first, or at least that part of the manual where it talks of needles and starting and tuning and running. (i think i left out the covers only)
Ramesh

yes rameshji....the link iam trying there is some error...i will scan teh necessary pages n send it to u after lunch. do u have a bsnl 3G connection?

i have a airtel broad band for my internet, unlimited download.
Ramesh.

no no i mean..i have bsnl 3g...it is easier to video conference with the phone...i can have it near the car...coz i dont have a laptop n webcam...only bband connection in a desktop

gopi,
sorry man, no 3G phone in my pocket as yet.
Ramesh

ramesh pls chk ur mail. sent scanned pages of manual.

Gopi,
Waiting , now come as yet.
Ramesh

got it?

yes Reading it.
Ramesh

Gopi.
Have read the manual, now make sure u main needle is 2 1/2 turns open from fully closed. on the other side, there is a screw head visible, it should be .8 to 1 mm form the surface of its collar, just check that again. open throttle till the carb is open about 1 to 2 mm, block the exhaust with ur finger, and pull starter 3 to 4 times, depending on ur fuel tube material, u should see fuel being rushed to carb, now put booster, and pull 4 to 5 times, she should fire.

Rameshji....i checked n tried the above steps but nothing happened...if i keep pulling the cord for sometime...later if i turn the car upside down, unburnt fuel n oil drips out of the exhaust

Gopi,
can u see the fuel being sucked to the carb. ok, one more stunt, just put a few drops of  fuel (half tea spoon) directly into the carb opening, and fire. also u still have not told, if after all this, when u take out the glow plug, is it dry or wet or really wet.
Ramesh

rameshji i would say the glow plug is wet...not very wet...i will try the 1/2 tea spoon fuel stunt 2day evening.

at times due to trying for a long time, a lot of castor oil gets accumulated inside the engine.. so. remove the glow, invert the car, and pull starter  a few times, before u attempt again anything.
Ramesh Tahlan

rameshji sorry...tried all the steps patiently.....still no results!! i think i will go into depression 

only option left is to ship it to me, hahaha
Regards
Ramesh Tahlan.

Since fuel flow has been confirmed, the suspect is the fuel itself ?  Nobody here can comment on the methanol used (looking at the picture of the fuel can posted earlier) ?

Was this fuel picked up from any RC related source ?

anwar.....methanol not from a rc related source!! i got it from a store which supplies chemicals to schools n colleges for labs. no rc stores in andamans!!

can u help me reg where i can get a new glow plug?

Since you are using no nitro, a hotter plug would be better.  The OS A3 is one, or you can OS #8.  These are available in many shops, I saw them at rotor.co.in.

Suggestions from others (especially car folks) solicited.
