I just got done trying to break my os .18 cv-rx in.

I have aluminum foil all over the cooling head and the temps are 130. What can I do? I still want to try to get some of it done today.

Also it seems really slow. When I just blip the throttle it really doesn't move. I almost have to pull the trigger half way to get it to move.

thats normal to not have any speed, just start leaning it out untill temps get to at least 200

Ok, thanks. I'll get back out there with my flashlight after dinner.

Can't wait until I get it done and can start ripping around.

130 = super rich. lean it out.

Tex · (#5 (**permalink**))

how many tanks did you do at 130F

UE-Maxx · (#6 (**permalink**))

None. I stopped. I just got it running at 210. I did one 3 minute run, then cool at BDC. Going to maybe do one or two more 3 minute runs after I eat.

I had to lift the wheels off the ground. It would always die if I tried driving it.

Just lean the LSN a bit until it's driveable....Then stop leaning it and stay where the settings are at.

Well I am done for today. I think my glow ignitor battery is dead. I just got done charging it fully before I used it. I thought I burnt a plug because it didn't light, and the second plug light barely, but didn't after the first time.

So I will be back tomorrow. I have nothing going after school so I should be able to get it done tomorrow if no unexpected problems occur.

Should I do after run procedure or just let it go until tomorrow?

Mr. Tune · (#10 (**permalink**))

Personally, I don't use afterrun oil. I'll use a little wd-40 if the motor will sit for more than 2 weeks without being started, but that's about it.

For 1 night, I don't think it's required.

Tex · (#11 (**permalink**))

no oil

UE-Maxx · (#12 (**permalink**))

I use WD-40 also. Alot cheaper and a lot of people recommend it.

I already did after run. Hopefully my ignitor doesn't go bad tomorrow and I can finish break-in.

I use Marvel Mystery oil for after run if I use it at all. Many of the store bought Rc specific After run oils I've bought over the years end up being nothing but Marvel mystery oil or trans fluid.

And what do you? Just pour it it or put it in like a spray bottle? I don't know how thick it is so I am not sure if it will fit in a spray bottle.

SixVi6-Camaro · (#15 (**permalink**))

For after run use just pull out the glow plug. put a few drops into the engine and crank it over once and its done. all you want is the oil to coat everything inside the engine and keep moisture from rusting the bearings and crank.

Normaly I don't use after run oil. The only times I do use it is on engines that are tight or engine that I just repaired or had apart that I want to be sure there is oil in the case when I first crank it or if its damp out when I run the engine.

Alright thanks.
