250 WHAAAAAAAAAAA.

the loktite on the engine mount screws. It is a good idea to use it on any metel contacts, But I have never use it there & never had them come loose. This is on 2 trucks that I have had.

I'm gonna rebuild my NT all this week for its first outing this sunday. So I'll be sure to do the screws correctly this time.

D Mac - Your LSN may be too lean. When it's cold, the engine should be making power around 190-200, and never higher than 210 or so.

But then again..my engines have never run hot! What fuel are you using?

D MAC

Aarons the expert here. However, here's my 2 cents!

I have been running the Drake for about a month now. It makes lots of power at about 200 degrees. However, I found that it likes the LSN to be about 1 to 1 1/4 turns out from flush. I would start with the HSN at about 3 3/4 turns and lean it from there if you need to. Another way you can tell if the LSN is too lean is if the motor stay at a high idle over jumps or coming into turns. Also, if it idles longer than about 20 seconds without loading up the LSN is likely too lean.

I run Trinity Platnuim 20% and an MC59 plug. Also, as per the Drake, run about .22 squish once the engine is completely broken in. The motor comes with a .007 and .005 shim. I removed the .007 and its perfect.

You will love this motor. However, it makes plenty of ponies at between 200 and 210 degrees.

Good Racing.

One additional thing to remember, motors generally need to be riched a few clicks when its cold.

I know thats the opposite of what you might think, but I learned that in motocross tuning and it seems to apply to my RC engines as well.

Aaron,

while I'm taking apart my car and engine, would it be worth taking the clutch apart and checking the wear? Its only got about 4 full tanks through it. What exactly goes into cleaning the clutch? Is it as easy as wiping it clean?...is sandpaper involved?

Also, if I make the main this weekend, it's a 30 minute race. Would it be wise rebuild the diff for the main...or whould it make a whole race day?

Thanks!

slotting the screws is probably not the best idea in the world. when i got my truck 2 of the tranny mount screws were slotted, and one of them broke taking it out a few weeks later
Huh, I never had that problem. I ran mine slotted all year long, on some big/rough track. Maybe yours were cut to far. When I slot them I do a little at a time and test fit to the screw driver for each one. Just my little thing, not many people do it I know of.

And for the question of rebuilding the diff before a 30 minute main. I would say if it was good up until the main, run it. My diff is gone thru after every race day. So it's always fresh for race day. Maybe if I was going to bigger races I'd do it, but I really doubt it.

Thanks guys for the tips on the engine.

Aw currently running Od fuel, thinking of switching to maxys.

Today without touching the needles was hauling a$$ at 215.

but did idle a little high off jumps, I guess richin the bottom a little?

So it comes with two shims and I should remove one?

THanks

Todd - Those two posts were dialed!

mafia - I never really disassemble my clutches. Your diff from qualifying should be fine for the main event unless it's very gritty. I wouldn't run a new one because it may loosen up as it breaks in.

D Mac - Between those two, I'd stick with O'Donnell. If at all possible, give Trinity Race Blend/Platinum a try. I'm not trying to pull your arm at all; you will notice a drop in temperatures and more power.

If your idle doesn't come down very quickly, you'll need to richen the bottom end. As Todd said, take out the thicker of the two shims.

Sofast-NT - Jesse's engines have rocked at all the races I've seen him run them at. I don't know much else about them other than Jesse being really happy with them.

D-Mac - No problem!

Aaron,

where should the idle be set? Right now, it will idle all day with a VERY minimal rpm ripple.....but while its idling, it doesn't go. I have my brake set to that it sits still. Should it run at neutral? or sit?

Thanks!
