IMO a perfectly tuned engine runs slightly rich when the tank is full, and may go slightly lean as the tank runs dry....At mid tank it is dialed in ideal..........If an engine is run too lean it will detonate and start blowing glowplugs...especially so at the compression and clearance this OS 25 runs.... Just to show you I just popped the head off the 25 and snapped a couple of pics
I usually will get 2 gallons from each of my glowplugs, I run my engines literally wide open their entire lives, and it is not uncommon to run 10-15 gallons on a crank( depending on brand of course ).... If i ran lean I would be burning my crank pins down much faster...........Now sometimes there are limitations to how stable an engine holds its tune as we are extremely affected by the limitations of the fuel supply system....If a clunk in the tank folds over or hangs up out of the fuel supply the engine can go lean........Just like if a tank is over filled and the lid is snapped shut it can make the tune go very rich, very fast......A modified engine pumpng at 40 000 RPM needs its fuel, trust me......If it was lacking fuel you would hear it.... Just as in the video you can hear the clunk getting bucked around in the tank as the tank was nearly dry....These engine sag very fast is if there is an interruption in the fuel supply....
As you can see from my pictures this engine has not been run lean...crazy thing is it is running 0.35 mm /0.013" head clearance and 30 % nitro, temping at 220 coming off the track....if it was lean my glowplug would be incinerated and my head and piston would be sand blasted.......As you can see my plug coils are stacked perfectly, nice shiny finish on the coil...a slight wetness on the piston and head....a little extra carbon on the exhaust side...FYI this is still the original P4 I broke this engine in on...I haven't even bothered putting in the colder plugs yet.....
I should add the fuel used is mainly castor based..9% oil, 30 % nitro

This is a Clocked ninja. GRP made one at that.
No point in looking further than the first 10 seconds, the rest is just me ripping my XXL apart.

It was a pure joy to run that engine. Best engine I've ever had, held a tune for ever and idled so low you'd thing it would stall.
I had just sold it when that video was shot. Had 8 gallons on it, not one thing changed in it. No slop in the rod at all.

Which is the exact same engine that Maximo is running in his vid.. Also, one of the reasons for all of the wheel spin in Maximos vid is that, that is a brand spankin new track! How many brand spankin new tracks have you ever seen actually give you max traction? From what ive seen and heard from guys that build/maintenance tracks, it takes several years of sugaring and mixing to get the track soil just right.. Go into the ClockWorkRacing thread and take a look at the pics of the track, you can clearly see how loose that top soil is right now.. As far as a tune goes, Maximo is correct! Do you guys really know what tuning consists of or what the whole point of twisting the little screws is? It has to do with achieving the precise air to fuel ratio.. You have to have "X" amount of fuel for "X" amount of oxygen.. A lean condition is when there is too much oxygen and too little fuel, it will not make more power, but rather, it will cut out and lack power at the part of the powerband that is actually running lean.. A rich condition is when you have too much fuel for a given amount of oxygen. Which will cause a rich condition making your R/C bog down..

all the stock engines run pretty much equal to each other in terms of performance..each one may have some areas where they pull better then others...some will pull better in buggies and other pull better in truggies...... The Orion Engines are top notch, so are OS and Nova's... The Werk's is also a top notch engine as well and priced killer to boot...a stock B5 pro will have no issues at all running with a Ninja in a truggy...tire choice, clutch, fuel and engine and chassis tuning will make all the difference and what should be addressed first....Pick a brand you like and go with it.... if your up against a better driver he's going to beat you no matter what you do, or what engine you run.....I can build you a wickedly fast engine, but I can't make you a faster racer...that just takes time , practice and experience !

You called me a novice and then bashed on my 8 year old son's VG ....
Had you just agreed a long time ago, all this would have not been.OP, if you want a moded engine, have a look around first.

Attempt to insult you? You called me a novice and then bashed on my 8 year old son's VG ....
