Hey, I would like to know what are the factory carb settings for this engine

The factory settings of the engine are as following and are a good starting point for you. Turn in the needles completely (Caution: Do not
over tighten them!) and loosen them the required number of turns:

Idle screw: Should be open 0.5-1.0mm.

Low speed needle: Should be open: 6,75 turns

High speed needle:Should be open 5,00 turns

CARBURATING PICCO ENGINES
Engine works better on the rich side (HSN) and normally needs more than a couple of laps to reach the operational temp. Start on the rich side (HSN) and after 4 or 5 laps tune the engine. Doing this process on the bench (or starter box) normally overheats the engine driving you to a wrong tuning and maybe causing a damage. Set the engine a little bit rich (if you progressively open the carb, the engine responds quick but at 3/4 rpm becomes rich (not really 4 stroking but rich) Then at the track after several laps (at least 5) if the engine is still rich lean it.

Regarding LSN, Run the LSN a little bit on the rich side and still keeping the engine with a good idle (Very low rpm idle, is better for fuel consumption and handling of the car after off throttle).
After pre-heating the engine, just pinch the fuel line and if the rpm remains the same for 4 to 5 seconds and then the engine revs up and shuts off, that’s the best setting for a large track with long straight away. If the track is really short, and full of hairpins, LSN needs to be more lean, because the engine never revs up for a lot of time, and so if you keep the same setup described before it is always rich out of the corner.

Sweet!.. Can't wait for the weekend..
Thanks.

Guys,

Can you give me the info on bearing sizes for this engine ?, i have a red dot .12 jlr that needs new bearings,

thanks,

Inside bearing 12 x 21 x 5mm MR6801-TH9/C3 (you can use from OS TZ engines)
Front bearing 6 x 16 x 5mm MR616ZZ (any picco based engine like the Mega)

What are the differences between this engine and the Off-Road Red Dot? The local hobby shop has an off-road sitting on the shelf and I was wondering how it would do in an NTC3

Off road engnes have more torque, while onroad engines have higher rpm.
I have four tuned Red dots, and with the correct pipe, they run great.
Dont waste your money on an off-road engine even though it would fit the car.
Pick up the tuned Red Dot, pipe and header.
The NTC3 will scream with that combo.

What pipe+manifold would you recommend for JLR?

I picked up one of these motors (used) and it did not have the tapered collet (where the flywheel attaches to). I am having trouble trying to locate one as it is not a standard size. It looks like it maybe 1/4 inch as 6mm is a bit too big.

The reason I asked about the off-road version is my LHS had one on the shelf. I've been looking to down-up-grade from my OS 18CVR which just doesnt rev very fast for desent acceleration. The choices at the LHS were this off-road version or an OS 12TZ, which was $50 more. I decided to get the off-road Red Dot and so far I am loving it in the NTC3. Insane power, awesome acceleration, and our track really isnt even big enough for its power band, which is easily solveable by gearing. I may have the LHS order the on-road version and put the one I have now in my RC10GT for the dirt track.

get the picco 2607 pipe with matching manifold!

the picco 2607 pipe is discontinued.. get the picco 2651.. kamikaze has them
if you can't manage to find a 2607 that is..

Thanks guys!
And what du think about 2652 from novarossi?
Has anybody tried it with JLR?
