Hi Brian, Make sure you have good fuel.. and the CORRECT fuel. I would highly recommend "Sig Champion" fuel for 1/2A (.049) engines, if you can source it. Do NOT use "Cox Super Fuel".. because "Hobbico" (it's distributor) has been made aware that it is actually harmful to Cox engines.. and they are in the process of reformulating the blend to have the correct amount and ratio of castor oil and synthetic oil in the mix.

Also.. do not connect any higher than 1.5V DC to the glow-plug. Doing so will immediately burn-out the element/coil in the glow-head.

Your pull-starter may have a worn "band-spring". Search on ebay for "Cox pull-starter" parts.. and try to get some spares. It might be worth taking the pull-starter assembly apart to inspect/re-wind it. Check for broken pieces of the band-spring. I don't know too much about the pull-starter.. but if the band-spring is broken at an end; you may be able to cut it shorter.. and file new notches into the band, where it connects to the housing. If the pull-cord is worn.. you may be able to replace it with some 30# test fishing line; like "Spiderwire EZ braid". When you reassemble the pull-starter, spray the internal components with a dry-type silicone lube, so it winds/unwinds smoothly.

Lastly.. open the needle-valve a little more than the specified "running-setting".. to start the engine. It may not be getting enough fuel. If it starts and continues to run with a low "burbly" sound.. that's ok. Gradually close the needle-valve until the engine begins to speed up. It's a good practice to adjust back and forth between the low (burbly) setting, where the engine is getting plenty of fuel and lubrication.. and shortly "peaking it out" to higher rpm's.. to get used to the needle-valve setting. When you run the car on the track/pavement, you'll need to find the optimal setting as well. This can change with atmospheric conditions and different fuel-blends too.

Hope this helps.. Good luck!

Thanks Roddie!!!

So detailed advise,i will get a new spring for the engine see if still got the lose problem.

For the fuel,it's really hard to find the nitro with castor in my area,I'm use the Tornado 25% nitro fuel,the fuel include 10.5% ricinus and synthetic oils.Also two D battery for glow head.

Very strange situation in my engine right now .

I'm unable to start with muffler and throttle parts,but if I take off these two parts I can start the engine for no problem,but once put back it became no start only few time look like a little fire up.buy never run.

Anyone got some idea can share to me.

Thanks

Hi,
do you set the throttle right?
You have to start the engine at full throttle. otherwise the engine won't start. The throttle setting is not easy but if you open the muffler by removing the screw you can see the throttle valve. So you can correct the servo arm to full open.

I hope i can help you

Yes full throttle is required on the beetle and the mini from kyosho. I don`t know why yet, couse the f1 car starts mostly on a little bit more than idle speed (I guess because of the flywheel or clutchbell). On the F1 car they are ball beared.

Make sure the arm for the throttle valve is mounted correctly, it has to be tight outherwise the servo will move it from its center. The cylinder slits have to be beside of the right and left side if you look through the exhaust.

Be sure the cylinder is thigten too and of course the glow plug head works. The Kyosho Cox Car engines are machined very well, they do start with the correct fuel and heater and correct full speed needle very fast, 3 turns from the bottom is recommended. You can also try 2 1/2 turn from the bottom on full throttle if it don't start and add some fuel on the screen.

These engines need some experience on cars, they are little diva's. But once thy start you don`t get it to know that such a little old fashionable engine is able to make those nice screaming sound. Nothing is to match with a cox engine... Small Cox Logo

brianskate Sat Oct 25, 2014 1:27 am

Wow,i maybe got some mistake in cylinder slits direction,right now my setting is face to exhaust port(throttle valve) 6 o'clock direction,another in 12 o'clock direction,will try to make it to 9 and 3 o'clock direction later.

I'm totally understand what you guys explanation,no problem.

brianskate Tue Oct 28, 2014 5:19 am

It look like my start problem is not the cylinder slits direction,because my cylinder locked direction will be different once i installed the throttle valve part,right now i just put the washer(part 95) upside down the cylinder can be tighten like without throttle valve part,then my engine is started but unstable. Huh...

Maybe need some hard works Smoking

Ok,i can start my engine Small Cox Logo

in my hand for no big problem right now,but once install to chassis the zip starter become a nightmare,really hard to start the engine again. Shocked

thanks everyone who gave me some idea for start the engine. Clapping

bnitram Wed Nov 05, 2014 8:45 am

Hello brianskate,
that is a good news. Do you have the muffler also installed when you start it in your hand? What is in the chassis difference ? Is the starter sluggish? Does the starter spring works ?

PS:
in a few days I get my new boby because the VW Beetle is in too bad conditions. It will be a "Alfa Romeo Gulia Sprint GTA". I will post some pictures when I get it.

@fredvon4
I don't think that this thread, a CAR thread, is the right place for life discussion.
Not without reason there is a introduction thread.

Hi guys,no problem,I'm just a normal rc cox Small Cox Logo

fans from far far away Taiwan.

Glad to know some body had been stay in my country.

Yesterday I finally start the engine on chassis cheers

Also play a while the throttle valve and needle valve with finger,right now I'm going to assemble all chassis then try it again,the zip starter look like really not good for start the cox engine,I already order some new spring part,will going to replace once I received,maybe can turn the zip starter more strong and easy start.

I will post some picture or video once I start the engine. Very Happy
