Default plug

get the odonnell 99 standard plug or mccoy mc9 they will both work I dont think they make the 97std any more and do what Tony said, if that does not work you could have hurt your rear bearing when you got your motor that hot. I had a motor that ran hot like that when it was new and it was a bad bearing from the factory.

could the rich bottom be why it is still blowing out smoke but running lean as well. thanks

It will all depend on what it does when you richen the top, If the idle drops way down then yes... lean the bottom alittle..... I suspect your fat on bottom and lean on to like you said

I can tell that the plug is short from that pic, but I can't tell the condition it's in because it looks fuzzy. Your engine looks fine. I honestly think that SideWinder ill discolour your engine before OD fuel ( I quit using Sidewinder for that particular reason ), but that's all personal preference.

Don't tune to temp, it's a big mistake and will cause you more headaches than it cures. I have an OD temp gun and it's no more accurate than my other 2. Temp guns have to be calibrated in order to work properly, and even so, all it takes is a little dust on the gun's 'eye' for it to throw the temp readings off.

The only time I use my temp gun is when I break in an engine, after that, I never use it at the track, and I rarely have any engine troubles. Tune to the sound and performance of an engine, if the engine gets lean you will hear and see it in most cases.

What plugs are available at your local track ?
Does it happen to be a pull start 3 port .28 ?

Don't expect much performance out of it if it is one of those engines , in the rpm range anyway . The plug isn't causing the heat , the bearing very well could be the coulprit , you might need a new rear bearing and pssibly have a misaligned crank . Rbmods straightens cranks and does it very well . As far as plugs and stuff , you should be running a medium hot plug , if its a standard then I would say mccoy mc8 , odonnell 100 and run 30% nitro .


Have somebody check the temps with an exergen gun and check yours against it for comparison .

What pipe are you running by the way ?

The wrong pipe can cause heat also

im running an hpi pipe. which i will be changing soon.
no it's not a 3 port pullstart. It's a 5 port 528x.
my local track only sells o.s. plugs so i'll just have to get them to stock something else lol.
im going to just richen up the top and start my tune over. i checked the bearings and they don't seem to be bad and they are moving freely. could they be bad and still seem to work properly?

yes on the bearings and if they aren't gritty feeling when you pose side deflection pressure and rotate the end of the crank all directions then you are probably ok .

as far as plugs , they are readily available on here if you need some

its either a 3 port or an 8 port , havent seen a 528 5 port , i see the insides of most all nova engines the 8 port doesnt usually come in standard either , its usually a turbo engine , did you get this new ? or used ?

happy motorin',
monty

and yes i would suggest changing that pipe out , whats the engine in ? will a dynamite 007ht fit ? that is a badass pipe for .28 engines

it's the 3 port, i just went and looked at it. I did get it used but it looked fairly new when i got it. It's in a lightning stadium2 pro truggy. I'll check out that pipe.
the exhaust port doesnt count as a port right?

FYI, Rossi carbs are sensitive... if you are use to tuning "an hour at a time" like an OS, try "15 minutes." (just a tiny tweak)

The 528 is a Novarossi not a AXE Rossi Novarossi carbs are very easy to tune. Start rich out from flush on high and low and tune your top end after you get that start with the low end a hour at at time. Dont touch the idle until you get the tune good. This works for me.

PS make sure your motor is hot before you start to tune or just go to your local track and have some one tune it for you and show you how to tune, you can learn alot at you local track and most racers are nice. It is hard to explain how to tune on a forum and if your local hobby shop guy is selling you os plugs I don't think I would go ask him for advice.
