Like I said in the FX thread, it depends. How does it run? If it runs fine, has all the power you want, idles fine etc then it's exactly where your engine wants it.

Why do people focus so much on idle gap instead of just tuning their low end the setting it to have a steady idle, whatever that may be. Also how can you measure a gap with no insert? Do you not run one?

if you are experienced with how to tune, the idle gap sort of just comes naturally. If you are a beginner, measuring it can be a helpful tool with respect to obtaining a setting close to correct, as most beginners at anything are not in fact experts from day 1. Hope this explains the phenomenon.

ah. makes a little more sense now. I guess I just had old school teachers 10 years ago and iv never even measured idle gap for my cars, planes, helicopters, or boats lol. but I hear it talked about all the time now. hmmm. strange lol

This made me laugh^^^ haha

Lets say you run a 6mm insert and most carbs are 9mm, that's 1,5mm opening of the throttle just to get it to the edge of the insert. So add say 0,5mm to that and you now have the carb opened 2mm...
The insert doesn't block the carb bore in any way that makes it possible to tune it that way, the air will pass right by.

Found a good deal on these just thought I'd share for anyone looking to stock up on glow plugs... cheapest I've found so far. Shipping is like 4 bucks for usps first class.

Question: I have a Plus4BTT with a few gallons on it and was broke in well. Heat soaked and tuned if the engine dies it's hard as hell to start. It will not start until it sits for 5min or so. Heat soaked it's running about 220F or so in 90F weather. New plug and doing the same thing. Seems to have good pinch still when heat soaked. Running 20% Byrons. Please help.

Sounds like vapor lock

For those that are running the Elite 5...

Which pipe/mani combo do you feel provides the most overall power? Or best top end?

I'm considering either a stock Elite 5 or the TNS modified.

I previously ran the OS XZB Spec II and want to be sure I can get similar rip/power out of this Nova Elite.

Thx guys!

Werks 2058 works great with the p5 based engines, really good top end plus it's very smooth throughout the low to mid rpm range with plenty of useable power. Currently running it in my buggy and I'd say it's a pretty solid combo.

As far as Nova pipes 9886 with either 41032 or 41001 will make some stupid power especially with a modded engine.


If you stick with a stock mill and really want it to scream pop one of the shims out after it's broken in. Even dropping the shimstack down from .8mm to .7mm makes a huge difference with a good 30% race fuel

Anyone owned bonito, keep off 7 and mito? What is the difference, the older model is quite cheap to ignore

anyone know anything regarding the rex .28-8 engine like how much power do they have?

Stock Elite 5 will have nothing for a XZB Spec II no matter what you do .... However my modified Elite 5 will easily be faster and more powerful then a XZB Spec II ......
