The only problems i had with a conrod in my Evo 3 was when i forgot to change it after run in and about 8litres. Apart from that no failures with Picco conrods from evo 3 or 4

I think the new Nova is too expensive now. I try to pickup new Picco to see how does it perform.

Questions??

Hey Guys,

Do all Picco engines come with composite carbies ?

I'm considering getting one to try but this is the main thing holding me back.

I still have bad memories of my old RB Matrix with the composite carby it was the worst engine i have owned. Wouldn't idle properly and a barsted to tune.

Anyway all info is appreciated.

Thanks,

There has been a batch of conrods, in where the small-end bushing rotated in the conrod, due to lack of lubrication after this, they broke. I found 2 conrods in my engines, having this problem, but you can check this, and replace them before more damage is done....

M7H is correct the key here is that everyone has to understand that these are engines, machines. They are mechanical and need to be maintained. This goes for all engines not just Picco. You can't run the engine hard strip first gear and run a race like this and put it away not thinking that the engine needs to be checked for fatigue after these conditions. The issues are that the engines now are making more and more power then before same size though so the checking of the components are extremely important for the engine to stay in good shape.

Yes they do, but if aligned in a good straight line (very important) with your throttle servo, I don't see any possibility to give problems. Mind you, composite carbs. have the benefit that your are actually able to start your engine when hot (after a flame-out) an engine with an Alu. carb. is crap to start.

Also your experience with an RB engine, you can not reflect on Picco....

Don't worry about the carb, they work great.

With any engine, you want to have little to no play at all. Check the play with the piston at top dead center, just where it pops over but try and get it to stay up there, and then jiggle the crank - if it feels like it moves a lot, then I would say to replace the rod and piston pin.

The carbs have gone through 3 changes to make them good. I have not had one problem with the new evolution of carbs that are being used now. Where as in the past I understand they were hit or miss. But even then we solved those issues as well.

+1 I have used the update Idm Evo3 .21 carb & it was flawless no issues at all
This past weekend I ran the IDM EVO 4 .21 Modified very fast motor with great bottom as well no issue & the carb & tune was perfect

As for ? on the rod suggested change after a gallon or when doing engine maintenance I also look for any bubbles by the rod sitting on the crank piston DTC using engine oil maintenance & looking for play as well

I understand your hesitation.
Nova, good stuff, but you can only really compare and give comments about Picco (Based) engines, until you try one!...
And I'm pretty sure you will be pleasantly surprised!
You have never had that much bottom power!
