R/C Tech Forums - NOVAROSSI Engine thread....

nice to see a quick response!

Engine has about 1 1/2 gallons through it. ton of pinch on it.

i had 3 flame outs... all after jumps.

I changed the line, bearings and even the plug, fuel tank, gaskets and the car was very free. Here are my current needle setting...

4 turns out on LSN
1/2 in from flush on HSN.

Keep ideas flowing...

How about the pipe? I read on the clockwork thread about someone that changed motors, clutches, fuel lines, tanks, etc. Only to find out that at about the 3 min mark, the gumed up oil inside the pipe was heating up and closing down the pressure outlet. not allowing the tank to pressurize and the motor to run lean and flame out. Just a thought.

running the 9901 pipe... could it be that easy? sounds possible!

Maybe time for some crock pot antifreeze boiling.

What buggy is it? Is it possible that the flywheel touched the ground. I've seen stranger things happen. Chassis flex and flywheel touching the brake or something ?

This is likely as I like to run my buggies fast close to the ground.

Mugen MBX6r with BCE X3 chasis ( short rear brace installed. Spur Gear meshing is pretty good so there is room for chasis flex. Maybe I'm landing on the flywheel? That would be pretty unlucky to do this 3 times in 1 day though. it is possible.... I'll look into that.

What about tuning... At what temps should I perform the tuning? 200? My engines usually run about 235-250 but I tune at 190ish. Would it make ha much of a difference?

Try running a tank all the way through if possible and then tune. Just to make sure you are up to full operating tempature and the crankcase and chassis are soaked with heat.

2096/41021 or 9901/41021. I've been using 9886.

I do not like the 9886 on the P5. The 9901 is better IMO. The 9886 feels funky on the bottom.

That is exactly the type of advice I needed. Thanks.

Do the BTT engines operate at lower temps...on average than previous Novarossi engines?

they temp higher as the probe sits closer to the plug when temping ;)

What's the best way to temp the Nova? what is max temp from the top of the cooling head? Can you offer any advice on this? When things started to really feel and sound good I temped the motor at 260. I richened it to be safe but then started having some issues. Thoughts?
