no thats not true i ran in my os tr without the glow plug warmer on. "I THINK" the bottom end is to rich, try and lean the bottom end screw 1/8th of a turn till it has a better or more stable idle.

also what plug are you using? OS A3 would be ideal to run it in with as its a hot plug.

also with the glow plug warmer still on how does it idle? is the rpm very low? if so maybe just bump up the idle speed a little try turnning the idle screw inwards 1/4 to 1/2 of a turn

let us all know how you go :)

fyi i'm meant the os tr turbo and it came with the p6 plug....anyway i'll try to lean out the low needle and see how it goes....till later..thanks:D

wait before you lean the bottom end us how it idles with the glow plug warmer left on. im also thinking it could be that the idle is set to low. leaning off any engine during break in should be avoided only should it be done if it is set toooooo rich. as idealy you want a rich setting to properly lube your brand spanking new engine ;)

and the P6 turbo plug is a good plug to break it in with.

i've succesfully got the engine to idle without the glow heater on...i did lean 1/4 turn the low needle....

just fyi i am trying out the method used by josh cyrul that i read somewhere in this forum.
b4 this with my previous 2 engine which till now is still race capable, i use the idling break in method .

with this new method ( which i am still half way through) its opposite of the idling method. instead...after u warm up the engine a bit u can start with wot/wide open throttle for the 1st too the 4th tank with rich main needle setting....
up to this point what i've found out with the rich settings the engine can barely scream cause the extra load of fuel coming in...
signing off 4 now...after i finished the whole process i'll give an update on this break in .:D

breakin in updates:D

so i've finished total 8 tanks on the bench....

now left only 2 more tanks (cause according to the method another 2 tanks should be done on the track)

maybe this weekend i'll have time to finished the whole process.
:D hope it doesn't rain:nod: :D

On the bench?

Are you using an airplane prop on the engine?

:sneaky: ...i meant i did the beakin in of the ground....:)

Just wondering because my cousins and I did break-in a couple of years ago following an article using prop's on 4 Tower .15 engines.

Mounted them on a bench, Set 'em rich, wired the throttled wfo and ran 6 tanks through all of them simultaneously. None of them went over 210 F.

I use mine as a loaner truck for beginners and the thing still starts and runs strong after about 3 gallons.

rcabj
great stuff dude

i was gonna use josh's method as well on my new sirio but decided to go with the idle a tank doing the heat cycle and then 6 more tanks on the track set rich. and WOT

let us know how it performs as well.

haven't had time to finish the break in process yet..bz bz...

anyway .. can a nova/rb turbo plug be used on the os-tr/t?

no!!!
just use the OS turbo plugs.

:( so that means there r uncompatible to each other....thanks brain:)

just to let u know over here the nova plugs r cheaper than the os ....:nod: thought can save some money:nod: :D

I run Novarossi turbo plugs in my engine with no problems.

rc_king1
what problems would you look for?

break in update
 

hello again....i've just finished another 2 more tanks on the track like what josh explains...so the grand total of 10 tanks for this break in process.

during this break in i have not encountered major difficulties....i can say it went pretty smooth....

now it's ( the engine) is ready to be tuned up to its optimal racing conditions(probably next week:D :nod: bz..bz....)

for now..bye:)
