My Petrol RC car wont run witout glo start attached it cuts out after about 3 seconds of removing it it smells very fueley and puts out alot of smoke, and dosnt run well!!!!!! any one know how to adjust fueling there is a screw on the carb by the fueling point but screwed about with it and no change but only small amount of adjusting
any help would great

 

Blocked air inlet or dirt in carb jet.

.

 

just cleaned it all out,but runs fine with glostart in, it is using alot of fuel aswell!!!!! half a tank in about a minuite 75cc tank

 

As a general guide,screw the mixture screw right in and then unscrew 1 and a half turns,then adjust 1/8 th a turn either way to fine tune...if it revs to max then cuts out unscrew,if it is choking then screw in.
sounds like knackered glow plug though

regards mark

 

bloke at the shop said the glo plug was ok!!!!! and would be alright for a while
will try the mixture screw thing again

 

knacked glowplug i'd say

 

It might of been ok at the shop and might look ok,but they are like cossie plugs and dont perform so well under extreme pressure and can be fooked in seconds

 

well i will have a mess about with it today and take it back down there nxt week and get them to change it!

 

If its firing then there is a good chance that glo plug is ok...just screw mixture right in and then unscrew 1 and a half turns,restart and fine tune,job done

Surely you have spares if not then buy a pack next time you are in shop,you will need them

naaa i only just found it in ma garage went down special shop and they sorted me out with remote, transmitter, fuel tanks ect ect expensive but its worth it its worth about Ł200, so i tried to limit my spending

 

yey i do have spares!!!!!!!just found new glo plug in the bag so they did give me a new one!!!! gonna fit it now

 

just tested old glo plug and its no were near bright enough!!!!! so fit the new one here gose nothing! oh acctually i think the glo starter is flat now!!!

 

If it's using half a tank of fuel in a minute then it's running way too rich.
I don't know what make of car/engine you've got but you need to go back to the base settings and go from there.

Did it come with an insruction manual?

 

Depends.. some glow plugs are hot and some are cold.. normally the bigger engines .21+ need run better with colder plugs (from my expierence) and the smaller engines .12 .15 run better with a hot glowplug.. also put it back to base settings and then lean it slightly as base settings always run rich.

 

What fuel are you using ?, how OLD is it ?
tabetha

 

if this runs using a glow plug why isnt it considered diesel?

 

lol i dont know maybe because it dosnet run on diesel
the fuel is brand new bought it yesterda changed glo plug now runs without glo start but it dosnt go proper when u boot it just starts cutting out!!!!!!! i have tryed starting from beginng and adjusting but still no good even with the mixture in its still using too much fuel, gonna take it up ma local shop and get them to sort it!

 

Too much smoke, burning lots of Fuel? Sounds like its running far too rich, turn the screw down (the fuel mixture one)

you shouldnt have to touch the idle speed one tbh, what car isit?

i have just been out on my savage not long ago
