Hi BigC2007,

Always hard to explain..., Because these engines are made for maximum performance you need to take attention because of the tight fit of the piston/liner the engines are not easy to start at the very beginning and you need to be carefull with the rpm when the engine is new. Once the engine is run-in they are quite easy to tune. But this is my experience.
How many engines have you had experience with? brands and the problems you have encountered(or maybe not). If you tell me some more maybe I can guide you to a good solution.

Thanks Rody for the reply and I have ran 2 picco's 2 Novarossi's. And both picco's and novarossi's one was new and one was pre owned. Breaking in the new motors I have had the Novrossi's were the hardest to break in but I took my time and they seem to come out great.

Any issues came of both picco's that seem not to last long and both threw rod's.

That's my experience with Picco's too. They break in quickly and are very fast when new but by 2-3 gallons in they drop off and become very unstable.

I believe Novarossi's are manufactured to higher quality standards, better materials and tighter tolerances (OS is probably of similar ilk as it's Japanese and the Japanese are renowned for exacting standards). Thats why a Novarossi takes a lot longer to fully break in than something like a Picco.

However the end result of the longer break in is great performance for many many gallons. So whilst a bit more expensive than a Picco I think you get more value for money. Admittedly I haven't tried Picco's latest S1 engines and those may be better, I don't know.

Novarossi went through a bit of a black period when they were messing around with the XL stroke engines but the new Mitos are gold. Certainly my experience in 20+ years of playing with these things!

And your 20 years + are a blessing to guys like myself.

Not just me there are loads of guys here. Rody is one of the old guard! There isn't much about a nitro engine that gentleman doesn't know!! He's probably forgotten more than I'll ever know

If you have managed to pass the hard breakin process of the Novarossi then the VSR02 should not be a bigger problem. Just pre-heat well the engine for the first start and the first gallon and you should be OK.
If this would have been your first engine I would suggest a Picco, easier to run-in.
Carburetor setting should not be a problem, in general after the running-in I just needed to close more the idle needle and lower the idle and then just set the main-needle.

Rody,

Thanks for your time and advice.

wow dan u said that perfectly sir!!! one ? and problem with nova what is up with there glow plugs if u fart next to them they blow!!!????

I've been following this thread with interest, its not often that we get a legend to answer our questions. A bit off topic, what do you think about the EBIS break in method Mr. Roem?

Not my experience with the newer 'B' line plugs. Some of the older plugs were very fragile which is why many of us started to run OS plugs at that time.

Dan what are "B" line plugs ? And I myself never really had issues with Novarossi plugs, I just think Ralph is just too damm fast any plug cant keep up with him.

These are the new plugs from Novarossi. Well I say new they've been around about a year. Identified by a 'B' at the end of the part number such as C8TGFB for a.12 engine and either C7TGFB or C8TGFB for a.21 depending on 16 or 25% nitro. The plugs have a wire that's been burnished which is basically a process that highly polishes the wire to remove surface imperfections which can be cause for wire failure during use.

Oh ok thanks Dan for the info, I think I may have one those new in package ready for my next run.

u do have a point there !! but even when I go easy they blow.. and I been blowing the b line also.. but I will not use os in my nova..

This.

Also, Picco had a reputation for tunning and carb issues in my racer circle several years back. I didin't care to find out if that has been eliminated and have just bough Nova stuff for many years. The only bad part is that their support is weak. I emailed them 5 times with no response and finally called Italy last night and spoke to a cute sounding gal. She quickly helped me with replacement parts I needed on some older engines I have. My Italian and hers were different.. even though our dialects were different, we were able to understand each other very well and I was able to get what I needed.
