Yes, you're right I'm going crazy with the numbers smh, number goes up temp goes down. I meant to say CT05 not 7.

But what you're saying according to chart if RP's are almost like nova plugs then that means compared to OS plugs even the CT05(Hot) is colder then there P5 plug?

So I guess the real question is can I go back to Nova plug or did I mess anything up with the OS plug?

Also I took apart engine. I have two shims .5 and .2 unlike what engine diagram says it should be (.3, .2, .3)

Would removing .2 shim be too much?

Sorry to be a pain but I really appreciate the help.

You can try 0.2 but I think it will be too much. You do not have an old broken engine you can use a 0.1mm shim from?

he still is asking this question. Can someone that knows answer.

I'd just stick with novarossi plugs if you can. There is nothing wrong with them. That's just an an OS fanboy talking crap.

Yes, still looking for an answer to this lol.

I figured.

Thanks

So the exploded view of the Rolling says its suppose to have two .3mm shims and .2mm making a total of .8mm of shimming.

When I took mine apart I have one .5mm shim and a .2mm shim making it a total of .7mm

should I still drop .1mm?

I had an old Nova that has two .3mm shims and a .1mm so I have the shim to do it now. (Thanks Roelof for suggestion)

From what i have read and heard, no, you cannot go back to Nova. You changed the taper on the button head by doing so, as the OS plugs have extra threads than Nova plugs.

When you have an engine die right after you remove the glow igniter it means that it is too rich. I had this happen to me during the weekend. I leaned out the LSN a bit until I got it to idle then went ahead and adjusted as needed.

No, Novarossi has the longest thread and so Nova plugs will damage the button head of other engines although the thread has nothing to do with the sealing, you only need to tighten the plug very hard to get it sealed on the taper. It only seems the taper of the plug is just a small degree different. You can swap back to Novarossi plugs, there is only a slight chance you will have a small leak that you can notice as some oil dirt arround the glowplug.

If I recall correctly, the width of the taper is different between OS and Novarossi, not the angle. So with a smaller contact surface you can depress a section if you tighten it hard, and if you change back to a wider contact surface it will now have to seal on a small band close to the threads, and that might not work too well.

And yes, some plugs have a different length on the threads etc.

Not sure if I should just pile on
to this thread...new nova p5, so much pinch i cant get the starter box to turn it over...heating it up with a heat gun and reading 200 degrees or so near the plug, will check battery on box, is this common with nova motors? Maybe heat more or perhaps I'm just getting a false reading near the surface but block isn't warm enough?I've had cheap motors before this and too much pinch was never a problem lol. Any help appreciated.

Check your voltage on your battery. A 4s lipo will have no problem either way. Use a Comp heater or equivalent, but you can also use a heat gun o hair dryer. Check case and plug for saturation. 200° is good

yeah I recall tons of pinch on my paloma at least. combined with break-in fuel was a real pain to do break-in.

Figured check here too on any tips for an issue I saw.

During main run about 5 minutes left engine started to feel like it lost power about mid throttle. was good low end and high end, just mid part lost something. Using buku clutch if that matters.

temped about 230ish . Engine is a Paloma .21 gold head.

still nitro newbie so open to anything to check. Making a list

Oh side question, heard about ways to pop dents out of pipes? some sort of freezing trick?

plug all the holes on the pipe using zip ties. Fill it with water and then put in the freezer and check on it every four hours or so. Will take about a good 8 hours to push them out, however if you leave it in there to long you could mess up the inside of the pipe. Good thing about Nova pipes is that you want have to give up a leg to get a new one like OS pipes.

If you plug all the holes, how to fill it with water?
