So my experience with novarossi plugs has not been good. I literally had 6 plug new out of the package not work. I had 3 old #6 plugs and 3 of the new #6 plugs bad out of the package. The only novarossi plug that I had work was the one that came with the engine. I have switched to O.S plugs and everything has been running great. As far as break in and what needle to start with. Start with the Low Speed needle. Lean it out so the engine will idle but still have some fuel spitting out. Keep temps at or above 200. I used my radio to open the throttle a little for the idle as well. After first tank I would slow drive it around my street for a couple tanks then start taking it up in rpm for a couple more tanks. After that take to the track and lean it out so you can get around the track but still a lot of smoke and temps 200-200 for a couple tanks. After that I would I was ready to go. A piece of advice for next time would be do EBIS break in. It’s cheaper then all the fuel you will use for break in plus all the time you spent. EBIS run 1 tank at idle. Run 1 tank at 1/2-3/4 throttle and your pretty much ready to go

I use a P3 O.S plug but I would have P3 and P4. P3 is ultra hot and P4 is hot. I believe the P4 would be closer to the CTO6. One thing to understand is once you put an O.S plug in your novarossi engine you have to stay with O.S plugs. The O.S plug has a slightly different thread. So once you use and O.S plug the novarossi plugs will not work.

Getting one bad plug here or there can happen. But 4 at one time? From Novarossi? That’s incredibly hard to believe. Your retailer should have exchanged them for you. No way would I personally EVER recommend any plug for a Novarossi other than a Novarossi plug. I think it bad advice to suggest a super hot plug either. Besides ruining the head, you’ll waste fuel and throw away free power.
I haven’t gotten any CT06 plugs yet as I’ve not run out of my first set of C6TGC plugs, and I probably won’t need to for a long time. I’m getting 2-3 gallons from one plug including breaking in from new.
Don’t give up on Nova plugs. Make your retailer that you got the supposed bad plugs from make it right and replace the bad plugs if in fact they’re bad. One thing I’ve found is Novarossi plugs (at least the C6TGC which are supposed to be the same as the CT06) like a little more heat from the battery. Meaning your glow driver needs to be in good condition with a strong battery. If the battery is old and/or weak, it won’t light the plug for crap.

You don’t have to believe it but that is what happened. I even put the 6 plugs in a different engine different glow igniter with the same result. I put an O.S plug in as suggested from another novarossi racer and have not had one problem after the switch. I could have sent them back but I already put an O.S plug in the engine so getting new nova plugs would not do me any good. I would not call this “bad advice” if it’s my experience. No one reading this has to use an O.S plug in their novarossi just because I am. Both of my engines run great with a P3 and my fuel mileage is just as good as anyone
else racing with me. Again this is my experience only so do what you want. I will continue to use O.S plugs in every one of my novarossi engines.

I got 1 more spare here lol so it will be what I keep around for now. For me the plug is from Novarossi direct USA that came with my Paloma engine , so looking to see if what they want to do about it, if anything. I'll actually be down where they are located in a few weeks here too.

Hello egobrkr,
As far as I know, the difference between O.S. and Novarossi Plug is at the taper end near the filament. The angle of taper is different.
Cheers..

Thank you. You very well could be right. I was told by a few people that the thread pitch was different and that is why once you use an O.S plug you have to stay O.S. I was told this by other racers with Novarossi engines that is O.S plugs. They have been doing this longer than I so I believed them. I know years ago a lot of people used O’don Plugs in their novarossi engines. I know the P3 works well for me but I know Monty Houston said that the P4 seems to be better suited for the novarossi engines. I will try a P4 at a later date.

Isn't it that the conical surface is different in size, so one plug might deform the head if you tighten the glow plug hard. Then the other glow plug will have a much smaller area to seal against.
Anyhow, the OS plugs is usually way to hot anyhow, I usually get more tuning issues and a lot less performance with hot glow plugs. Even the Novarossi is on the hot side, but each to his own I guess.
