i have this same engine and mine is modded by ceo power mods and it is super smooth and has a ton of power everywhere it is also pretty fast faster than the stock one i ran a gew years ago i am running a jp3 pipe and i am getting somewhere around 7 minutes to a tank but i am not sure if i have it tuned right because i was expecting to get longer run times than that with it i had issues with the stock carb so i put one off of my rb s5 anyways i am happy with it

I had great success with this engine and managed to win quite a few races as well. It isnt the fastest engine out there but the power band is very linear which is why it makes the car very driveable and it puts all the power down to the ground. I did use the carb from another novarossi engine though.

I read the above two posts and I also had problems with the carb. I got the carb off my ninja engine and it's working perfectly now. I can finally finish breaking in my engine.

I really like this engine as well. I've got about 1.5 gallons on mine and couldn't be happier. No carb probs here.
I've run the JP3 and felt like it really held the top end back.
I put a dynamite 086 on and it really woke up. Really smooth, easy to drive and tune.
Tried the 2035 as well and it performed well on a small track, I need to get it out on the bigger track to see how this combo really works though.
More than likely when this one wears out I'll buy another, it's really a great value and probably plenty of engine for many drivers.

I have a a Novarossi pipe on it right now. The carb needles were EXTREMELY tight. Having to use effort to turn a high speed needle is not what I expected or think is normal. I just threw the carb from my MR21 and it works fine now.

Another thing drfmf1, what type of clutches did you use and what type of springs? I put on some carbon shoes but I think the springs are too hard and it's taking too long before the clutch engages. Any ideas?

paddyhong,

I'm using a pretty straightforward clutch setup right now. Using the the ae clutch on my rc8. Impulse-rc shoes (6061) with all 1.0 springs, stock cb.
With the 086 it really woke up the top, but the bottom softened up a bit, so, if the 2035 isn't to my liking I may put the 086 back on and bump at least 2 of the springs to 1.1 to try and get a little more snap for those jumps with shorter run ups.
Also, sorry to hear about the carb troubles, I really had no problems at all. I found it easy to tune and it holds a tune well too. Glad to hear you have it worked out though.

drfmf1,

I see... I tried the Fironi clutches (the two piece slide ones) and they didn't work because I put too many springs. This time i'm trying just one spring to see how it works. I also tried, carbon shoes on a standard clutch but I think the springs are too hard. It would only engage during mid rpm's... Both of these setups were with a vented OFNA clutch bell and brand new ceramic bearings.

Were your carb needles really hard to turn in and out?

The needle issue is fixed. I was advised by MikeB to oil them and it'll be fine. Smooth as silk now. =)

I didn't have any problems with mine.
All in all just really pleased with this engine. It is a great value.
