I hope you guys know that new engines are hard to start because they have lots of pinch.The picco has alot more pinch than that 3.3 you are use to.And if you guys are using that crappy ezstart to turn these things over on break in than you can pretty much forget it.New motors are going to be hard to start and when they do start you will hear a metallic noise coming out of the exhaust.That mettalic noise is the "pinch" engines iternals banging into eachother and it will gradually go away once everything is completely broken in.If you want a easy break in than get yourself a heat gun and temp gun.Heat the motor up with the heat gun till it gets 200 degrees on the head button and then put a freshly charged glow plug igniter on it and turn it over with your freshly charged rotostart or starter box.Maybe you got a bad motor but I doubt it.I feel sorry for the bad rep that picco gets from you guys.Picco builds some of the best engines out there and for a damn good price compared to others.Before you guys go posting things like "the carbs leak" or "the bearings are bad" I suggest you take your vehicle to the local hobby shop and hopefully someone there knows what they are doing and can get it running for you instead of damaging piccos rep.

man nobodys ruining piccos rep. go to ofna.com and look there announcements and recall list. they'll tell you that they have made some mills with bad bearings

call dave or jeff at ofna and theyll tell you that the bearings are bad and to send it back.

come do a leak test on my motor and youll c air come through the bearings. IT IS NOT NORMAL!

hey u were probably one of the lucky guys who started their motor and have had 0 problems with it and u know what good 4 u.

but if u were in my prediciment u'd be on the computer wanting to know whats up just the same way me and all the others have so dont give me that mess about ruining somebodys rep...

as far as picco goes, hey i cant wait to get it back. ive defended this motor all weekend when the rest of my buddies were laughing calling it a POS

once again thank u for ur reply.

heh did it. i had that carb off and apart at least 3 times. i cleaned throughly with compressed air and 2 plus 2 everytime.

the carb was always spotless everytime i inspected it but i cleaned it for piece of mind.

the crank bearnings the problem not the carb

so your saying that even when you blow into the exhaust pressure line no fuel feeds into the motor ? or does the fuel hit the carb and not go much further ? if its the second reason then all that is happening to you is that the crank window is likely closed when your trying to prime it which will not allow the fuel pass into the motor.....You need to rotate the crank some to get the window to open then try priming again... Its is absolutely impossible to not be able to prime a engine manually like I am describing..... bad bearings have absolutely nothing to do with the symptoms your describing, there is no way a bad bearing will not allow you to be able to prime a motor manually by blowing into the exhaust pressure line, nor will changing the bearing change the way the motor sucks fuel from the tank..... The issues with priming this engine are due to your inexperience and nothing else, please trust me when I tell you that you need to settle down and listen to what I am telling you... PM me if you wish to talk and I will gladly guide you over some basics over the phone and I promise you that in no time you have this motor purring like a kitten...... All the issues your describing have absolutely nothing to do with a front bearing seal whatsoever so sending the motor in for bearing replacement is noit going to help your cause any... You need to learn a few more technical tricks with priming and starting and nothing else.....

the motor will not run. turns over fine, seems to have compression(very hard to turn flywheel), but will not run. when i removed the fuel line from the carb and cranked the motor over no fuel would come out until i held my finger over the exhaust.

right here tells me you still do not understand how the fuel system on these things work.... these motors do not have fuel pumps, they use exhaust pressure to pressurize the fuel tank combined with the negative pressure at the venturi to create somewhat of a assisted syphon....... in order for this sytem to work the engine must be running, and unless the motor is running it will never create any sort of usable fuel pressure...... even turning over the motor with the EZ start with tuned pipe plugged will never create enough fuel pressure to prime the engine, by blocking the end of the tuned pipe you help harness slightly more pressure but it will never ever ever ever be enough pressure to prime your new Picco.... One big reason is the Picco is insanely tight and your EZ start will never, and I mean NEVER spin that motor fast enough to get any sort of dry prime like your expecting......... Your issues are 100% with your priming methods and nothing else... if you listen to me you will have your motor running in no time....,.... I can honestly tell from your post that you just need a little help and nothing more, remember we all had to start somewhere, there is no shame in being new to something and not knowing proper procedure...its all part of life everyone has to go thru........

when blowing into the exhaust pressure line i cranked the motor over at the same time. Let me claify, i am using a rotostart system.

i thought it wascalled a easystart, but appearantly that is the stock starting system made by traxxas

thank you supertib and the rest of u guys for ur time, generousity and advice. my picco is at ofna now.

maybe the bearings arnt the cause, but im having them replaced because theres no sense in having a leaky bearing fresh out of the box.

supertip i have a feeling ill be pm'ing u in the near furture.

thanks again.

ross

It is normal for some front bearings to leak alittle afo after sitting and it will not effect the tune.I did not see the announcements and recall list.Can you give me the link to it?Don't get me wrong this is not an attack on you.I am just saying you guys need to take a chill pill and stop posting things like this and go to the hobbyshop (in your case hobbytown) and get them to get it running for you if you can't.Also there is a thread on this forum called the darkside.I suggest you read all of it and if you have any questions just ask.I drive through frederick everday and can get that thing running for you if you like.

This is all very true what supertib is saying; maybe u just need to take a short "breather, or break" from the r/c scene for a week or 2 or however long it may take u to "Relax" and give urself time to calm down and take a second look at things in a new light, at which time maybe u will be able to better understand where we are coming from. And I agree that u just need a little help and that indeed, u just need to relax and take a step back from things for a short time, then come back to them when u have a clearer mind to be able to think these things through a bit more logically.....just my thoughts here....

I think this guy is relaxed enough. He's talking calm the whole time and has listened to everyones suggestions. We'll see what happens when the motor comes back from Ofna.
