Right this engine just will not RUN with decent power. The starter just broke so I just replaced it after 5 days of unuse and with the same settings which it started on, ITS DEAD. It fired up but the engine wont rev and if it does it boggs down and stalls. The engine has never ran properly really and I know they are fine tuned but FOR GOD SAKE. I looked and there is a tiny amount of scoring down the barrel but it still runs (as in starts).

I really cannot be bothered with this engine anymore as it is just wearing me down while it seems all you guys are having fun. What do you all think I should do?

Any thoughts on this engine to replace the nt-16?

Ok I still want a new engine but this has confused me. The car ran on the floor but got slower and slower untill it cut out whic took about 30 seconds of extremely low speed movement on the ground. Which needle should I ajust for this? In my mind it is running to ritch. But on what needle?

Definately sounds as if it is running too rich... Was it all "blubbery", as if the engine was struggling to reach high rpm's?

I think you need to adjust both the needles, try adjusting the low-speed so that it will idle properly, then as you increase the revs adjust the main needle so that it runs properly throughout the entire powerband. Usually i would reccomend adjusting the main needle first, but an engine that is very difficult to start will benefit more from adjustment on the low-speed needle.

Have you checked for air leaks, drivetrain issues, clutch problems etc? There may be another problem which is affecting the engine, such as a crack in the fuel tank etc. Don't give up on your engine just yet, there could be a very simple solution...

LOL SNOWBL!ND SAVES ME AGIN......I am gonna try but I still kinda want a new .18 engine. Snowbl!nd are there any you reccomend m8? I want a cheap but good one at around the £40-60 mark. I was looking at thease.

The £40 - £60 mark... I doubt you could get ANY new engine for that amount. Seroiusly, you are going to want to double that amount if you want a decent .18 engine. Have a look at OS and HPI engines, they are reliable and relatively inexpensive. If you find an engine you like you may be able to get it fairly cheap online - MAYBE you could get a .18 shipped from the US for £60, but you'd have to be very lucky indeed.

What type of vehicle is the engine for, if it's a 1/10 touring car or small buggy a .12 should do, and still be faster than the .16. I could reccomend a few .12's if that would help??

And yeah, i do seem to reply to a lot of your posts!

Its the CEN fun factor rally buggy.

Hmmm.....

It looks quite beefy so i'm guessing it weighs a fair bit. So that definately qualifies it for a BB (big bore at least) engine.

The minimum ££ you're looking at is about £60 - £80 for a .15, .16 or .18 engine. More for OS and HPI engines (around the £100 mark). I think the best bet would be to go to a model shop which stocks nitro engines and ask what they've got. Tell them you want vehicle it's for and how much you are willing to spend. They will probably be able to help you out.

That help at all?

Also what happens is that it reves at medium to high rpm's but if you let off after that it stalls out. Is seems to also "lag" when you hit the throttle from a slow speed.

This engine was reccomended for the fun factors in another post here - http://www.rcuniverse.com/forum/m_3995290/tm.htm

LOL I have £750 which I just got for a 2001 KX85 and I found this OS - http://cgi.ebay.co.uk/O-S-11880-18-C...QQcmdZViewItem

Its only around £62!

When you say it "lags" when you nail the throttle does it pump out lots of smoke or not? If it doesn't it's too lean, too rich if there is a lot of smoke.

I'm not quite sure what it means when the engine cuts out after you let off the throttle, i've never come accross that particular problem with any of my engines. Adjusting the low speed needle according to the above statement (the smoke bit) should solve the problem, my guess is that the engine is too lean on the low-speed needle.

I've had a quick look at the .18 Infinity engine, it looks OK, althought it is definately not in the same league as OS engines and the like. If you tune it correctly it should be OK in your buggy, and i suspect it will produce more power than the stock .16. If you do decide to get the engine, make sure you get the correct type of carb and crankshaft - match it up to the stock engine.

PS. The ebay link you posted works out at £42 SHIPPED for the engine - not too bad considering. Even if the engine isn't great it's still only £43...

What I mean is that after the car has been in a high RPM fange for a few seconds and you drop the revs the engine stalls out. It does puff out a lot of smoke tho.

Yeah, i know what you meant - i just didn't know whether a lean or rich condition would cause that problem. A lot of smoke would indicate too rich, so try leaning the LSN.

The OS engine you posted a link to would be much better than the Team Infinity engine, and around £70 (inc. shipping) isn't bad! You would probably be paying £100 for that same engine if you bought it from the UK. I

I take it your not just buying a engine for its performance, will it be easyer to tune?[&:] I am not a idiot and I want to learn but I also want to have fun racing it in my feilds. Im gonna build a track on them.

Yes, OS produce some of the most reliable and easy to tune engines on the market. Not only will it be more powerful, reliable, easier to tune, but it will also last longer than a cheaper engine.

I went on sunday with my MGT and had a great time. Good weather, fantastic track and very friendly racers (generous also - two people helped keep me running by supplying me with spares!)

It might be too far for you to travel, but i'd strongly reccomend it.

Well I live in stafford ATM so I dont know how far. Its gotta be cheaper than motocross tho. lol it was £40 in total for 1 days racing in motocross. Ill check that out m8.

Ill have a go at tuning it again tomorrow and if I have no luck I will probs get that OS engine with barrel carb.

Looking at google earth it's going to be about 50-60 miles - about an hour on the motorway.

Definately worth it, i was there at 9:50AM on Sunday, left at about 4:30! The whole day cost me only £6! And i had UNLIMITED use of the track, most of the people there have spectrum radios, so no frequency conflicts.

Ok before I buy the OS .18 CV-RX does anyone have any further suggestions or a better engine?

Ok I have gone from setting to setting and I got it on the ground but it only moves for about 10 seconds and then dies away and stalls. I am now thinking to get the CV-RX and take the car to my local hobby shop and get them to try get it running. I am also thinking that even if the car runs on the nt-16 it would still be a good move to get a OS .18 CV-RX.

If you can get the nt-16 running properly you could always buy the .18 CV-RX and just keep the stock engine as a spare - it's always good to have a 2'nd engine lying around in case you need it.

Or you may decide that you don't need a new engine just yet - if the stock engine has never run properly you may be suprised by it when it comes to life...possibly.

Snowbl!nd have you got any settings which will make the NT-16 run without it cutting out every 10 seconds of running on the floor? I have gone around in circles realy.[:@]

I'm afraid not - i don't have that particular engine, and i can't even tell you the settings from either of my engines as i'm at uni and they're at home. Could post the settings tomorrow sometime if that would help?

Have you checked for other things - air leaks, cracked tank, clogged fuel filter etc???

Yes can you please post the settings. The engine has just been rebuilt and the tank is clean inside - it is just one of the most puzzleing things I have ever known.[&:]
ALSO IF ANYONE ELSE HAS THE NT-16 PLEASE POST YOUR SETTINGS.

OK, i'll post the settings tomorrow sometime. They will be the settings for a Novarossi .12 and a Thunder Tiger .21 but they might help.

And do a search for "NT-16 settings" on RCU, i'm sure you'll find the reccomended settings for the engine.

Just got the manual and look at the settings. - http://img209.imageshack.us/img209/3094/124ve.jpg

I ran the engine at thease settings and still got the same results. I take it the NT-16 SHOULD work at thease settings even if it already has been run in?
