Depending on where you live that might still be on the rich side of the overall tune.

Keep in mind that the engine ran well, minus the ghost flame-outs that prodded me to find that crack in the tank. I replaced that and re-tuned for my last qualifier and the main in which I had no more issues. A temp check at the end of the last qualifier showed a temp in the mid 240's, but since the nova still is pretty tight that didn't seem out of place. But now that I see where my needles were, I'm a little concerned as I thought the factory spec's were almost always on the rich side?

called ya Kyle!! :cry: no answer

Houston ?
how do you recommend tuning nova's, I know they can tune a little different then normal

best thing to do on nova is warm it up , clear it out a few times , listen to the idle , if it revs high then comes down without being "tingy" its still rich (richen hsn before doing this) , lean lsn until comes down and stays consistent , then adjust idle gap until you get the desired idle , it usually ends up very close to .6mm but there are alot of determining factors

It almost sounds to simple to work but it does. Just remember that both the LSN and HSN are sesitive and when you get it it close it may only take a 1/24 of a turn to put it in its sweet spot.
when tuning my LSN, the idle would raise or fall almost instantly with the LSN.

I think I must have the wrong number for you Monty, every time I tried to call I got a "your call cannot be completed as dialed" message.

Anyway, I had a friend do some tuning on my motor this past weekend and he ended up back where I was on the needles, so I'm guessing that's just where this motor wants to be for my elevation and climate. Roughly 5 1/4 out on the LSN and almost about 3 3/4 out on the HSN. Air gap is probably down to .4 I would guess, as I started at .6, but ended up closing it up quite a little bit.

This friend is telling me I need to run a P3 in the Nova as it will be more consistent than the Nova #6 longbody in it currently, but he also doesn't agree with me that by changing to the OS plug I will reshape the button and not be able to use the nova plugs again without changing out the button. He swears he changes back and forth in his own Nova's. Am I incorrect on this?

Personally I've never had any luck with using O.S. plugs with Novarossi engines.
Ive had better luck and more of a consistant tune running
Werks #5 and #6 plugs and O'Donnell 77T, 87T, and 97T plugs

Go to a number 5 plug before OS. the nova plugs are very durable and work great.

The werks are good too, if you compare a werks and nova plug side by side they look almost identical.

When you say ".6mm", are you talking about the gap between the throttle slide and the end of the opening? If this is the case how would you measure it?

Thanks

ya bill the idle gap

where the ( of the slide barrel and the ) of the carb body meet to leave a gap

==()==
distance in there should be around .6mm
