Running really rich will foul your plug.....might need to replace it.

Is the OS CV-R .15 a good engine? I know it is discontinued, but I have one in good shape. I have a CEN MT2 w/ the .16 in it and it screams, but was wondering if this would be a good backup/replacement. Just curious...........

Big-ED

So do I have it wrong?
DO I not want to be running it that rich for breakin?
I got almost three tanks thru her,I guess I can lean it out a litte more tomorrow right?

You are not doing anything wrong.....you will foul plugs during breakin because it is so rich. I would change the plug and lean it a little each tank. When you take the glow igniter off and it dies, it is usually the plug. This is just a breakin pain....I hate breaking in engines.

Big Ed -- at 2 1/2 tanks you should be running at 220 degrees and should start applying more throttle. You need to start running that thing or it will not break in at temps that you get during a race. I am not saying that you need to run full throttle for 20 seconds at a time - but you need to build some heat up in that thing. Sounds like Christian is correct in that it needs to be leaned out if it is running rich so you can get it up to 220 or so.

A fully charged glow plug igntor and a good plug always helps too!

Scott, Kevin and Christian are good guys to bounce questions off of for break-in and tuning.

Joe -- I don't have experience with the CEN engine or that OS .15 you speak of -- but a couple of us use the .21 OS RG and I am very impressed with it and it's power and speed -- so I would say give it a try.

Big Ed - Factory setting are always to rich to start with especially with the hot humid air we have here. For my break in I idle the first tank and adjust the low speed needle untill it holds a low steady idle without loading up but still have some smoke and oil spitting out the pipe and I always have it running atleast 180 degrees (colder temps means less expansion... less expansion means more friction and wear). 2nd tank I idle untill it gets up to atleast 180 degrees than I slowly run around on a flat surface close to idle and pulling the throttle for about 4 seconds then let it coast a little then pull a tiny bit of throttle again. 3rd-5th tank just keep running it faster after each tank and tunning it as I need to to make it stay up to temp and not to go higher than 220 degrees. 5th tank I just run it as hard as I normally would but I make sure its still running a little on the rich side.

Theres no best way to do it all you really need to do is make sure you have the temp where it needs to be with enough fuel going through to motor to keep the piston and sleve completly lubricated at all times and of corse keep it at low rpms atleast untill the 4th tank.

Big-ED

thanks guys, I'll lean it out a half turn or so when I start again and get the temps up.
I couldnt get it above like 140 for these first few tanks with the settings I was using, I thought it was better to have the extra fuel for lube and wasnt really thinking about getting the temps up yet...my mistake

Make shore you use a temp gun vary important. Make shore you get that piston and sleeve up to 200 through a tank before driveing. Some might say different but I can get 6 or more gallons through a motor.

now that's funny!!!!![sm=lol.gif][sm=lol.gif]

dockman2

Almost as funny as having that wheel come off with 5min to go and the Other green truck, you know the one that hit everything out there, was still running and finished the 20min main.

dockman2

Hey Bill, how you doing?

slicks

Not only did that green truck hit everything -- it hit everybody too!!! That was a nice truck - just the wrong set-up for racing.


Scott -- Looks like some of my plans have changed for the weekend and I'll be free around noon on Saturday -- I can come out and help you with some of the track work if you like. Also - maybe I can get a couple of tanks thru the Picco engine (2 should do it) and tune it so it can be used on Sunday. I think I can get out there around 1:00 pm if that is good.

Hey Matt -- if I can get my back-up buggy running you are welcome to use one of my buggies on Sunday if you want to race. Let me know so I can prepare other wise I'll only bring one buggy with me.

Scott and Kevin - I was thinking (can you smell the rubber burning?) it would be fun to run some sprint races. Probably not this Sunday -- but a race where who ever get to 3 laps first wins - it would be interesting/fun to see how that played out. What do you think?

trackman

joel the track looks pretty good. the whole thing has been swept, no more rocks. i removed 4 wheel barrels
of gravel from around all the pipes.it looks like a hard packed dirt track again. i put some calcium down
last night, will do so again before sunday. all the trophys are ready. stampy supplied the last 2 that i needed.
joel is amanda tied up all day,maybe she could call in sick!!!
i hope everyone can make it, and let me know how long you want the mains to be.

slicks

Scott --I think that Amanda won't be home until 4:00 or 5:00 on Sunday if I remember correctly. I know that the event is an overnight thing and that the kids usually don't get much sleep.

I know that she gets on here almost daily to read the forums --- HEY MANDERS -- what time are you getting home on Sunday? Do you want to see if mom can drop you off at Scotts instead of going directly home? Sounds like folks want you take part in the festivities - you know, food - drink - laughing at others!!! I have to ask this one - What about your homework?

As for the length of time for the races -- I think we may have to wait and see how many people show-up. If we go more than 5 minutes then we need people to pitt and marshall. If we have enough people - I say 10 minutes for the main. If we are going to eat and do the trophy thing we will need time for that as well. PARTICULARLY the EATING and DRINKING parts!!

Sounds like the track is in good shape with all of your work. Do you not want anyone running/tuning on it Saturday? I understand if that is the case. I can still be out there around 1:00 if you think you'll need additional help.

SManMTB

Now I have to show up after all the work you put in Scott.

trackman

i was trying to make you feel guilty. glad it worked!! you might have to carry the MAC win streak. whats that? dave who?
joel sat. afternoon is fine. i think a few people want to do some tuning. it looks like a different track
now that it is clean!!! i hope we can even get kevin to run.

trackman

rodney i havent seen you get 6 tanks without blowwing the motor!!!!!!

We haven't heard much from old #503 have we? I think that maybe he is too busy trying to figure out which dress to wear while handing out the trophies
