I just started up my new savage x 4.6 today to start breaking it in, well when i start cruising it around on the ground it does this really high pitch idle noise and stays there now. So i turned it off and tried again, and again the engine makes a high pitch steady noise, but when i hit the brake which usually would calm down an angry idle it stays high. As soon as i turn it off there is blue smoke coming from the area where the 2 gears are (not good with names) the one directly attached to the engine and the spur gear. Is there something near there that can free spin and cause the engine to sound like it's off the wheels amd cause smoke?
 
Actually about five minutes later I found out what it was. It made that high pitch noise again but this time even higher like someone lifted it completely off the wheels and the savage just sat there. I ran over and turned off the engine and found the spur gear completely destroyed, it stripped the hell out of it. Total BS it hasn't even been running for 15mins yet and not even half way broken in and already i have to wait a week till a part comes in.
 
human error. the first thing you do when you get any vehicle is check the gear mesh. the wrong mesh can not only rip through plastic, but also steel. i ruined a steel clutchbell like that.
 
Sorry I'm new to trucks is the gear mesh in the transmission? Or are you talking about how well the spur gear and clutch bell align up? Hopefully it's that cuz something in the transmission should not be wrecked from factory for some unsuspecting newbie to walk into AND not know what the hell he's looking at if he opens it up anyway. I can spin the wheels by spinning the spur gear with my fingers so it's dosent seem to be in a bind.

Proper mesh is important. Consider it a lesson learned. At least it's not an expensive one.

Now, on a side note, since when does the piston hitting the top of the sleeve make a high pitched whine?
 
The mesh they are talking about is the space between the spur gear and the clutchbell.
 
it may be the clutch as well, if the shoes are messed up they will heat up the clutch bell and melt the spur. may want to check that while you have it apart.
 
A metal spur is not going to solve your problem. The idle is too high causing the clutch to drag on the clutchbell. This causes heat, which melted the spur. True a metal one will not melt but other more expensive parts will fail. Double check the carb settings and try again. That engine should be idling slow not fast during it's intial break-in. It sounds like the LSN is too lean and/or the idle adj. is too high.
 
That makes perfect sense since i was struggling with the idle
Worst problems ever since I started this hobby and this is not my first new rtr.

The thing that scares me though is, like I said in the first opening post, the high pitch noise was a high idle it would do it out of no where and stay like that. It would idle fine when i start it and when it was rolling around it would stop with a perfect idle then about 40 seconds into it would high pitch idle like someone lifted it and nothing would stop it. The damn engine would freak out which then probably heated the clutchbell. I adjusted the idle needle but any less and it wouldn't stay running with brakes applied so the idle is perfect, something else is wrong and it sucks...i want a refund...

Damaged spur gear from from the butt end of a crappy series of events....

Crap load of fuel from the factory setting being retadely rich, hsn should be flush my ASS , perfect example of the manual lying.

I lost the battle today....

CONTACT HPI CUSTOMER SUPPORT. tHEY will send u everything that was messed up. Send them the pic u posted here and just tell them wat happend. But tell them to that its a factory mistake and that the clutch and shoes are gone too. They will send out a new one.
Or they might just say send the whole engine in and well give ya a new one.

no they wont. they are not going to send him a whole new engine. i still think that he didnt set the mesh. thats exactly ehat my plastic one did when i didnt set the mesh.
 
there is to much teeth left on the spur for it to have had good mesh, it was to far out. but that isnt what broke it... he said the idle was to high, sporadic idle is a good sign of a air leak somewhere in the system. you say you adjusted the idle, how did you do this? with the trim on the radio, or the screw on the carb? when it went to a high idle, would the truck try to move? did you have to hold the brakes to keep it from moving?
 
When it first happened I maxed out the trim on the radio and it did nothing to calm down the idle so I turned it off and turned it down on the carb and had to fine tune it on the radio to enable it to stay running, so I had it trimmed just enough on the radio to maintain a steady idle, but a minute or so of running on the ground and the idle would suddenly spike to a steady high buzz which at that point was helpless and yes brakes would need to be applied to keep it from moving. The only thing that calmed it down was when the rag was applied to the exhaust but when I released the rag it would spike again 5 seconds later. The spur gear went out seconds after the second spike.

I never did adjust the gear mesh, which yes was a lessoned learned. When I removed the engine a few minutes ago I noticed the position was maxed out away the the spur gear, but yes there is another problem here..there was black dust in the clutchbell to back up the high heating of the spur gear.
 
there is always black dust in the clutchbell. its made of....... of something that emits black dust. i truthfull dont know. rubber?
 
the clutchbell is steel, the black dust is plastic from the spur or clutch shoe dust...

the truck should idle without any help from the radio, you may have to give it a bit of gas to keep it running when you first start it but after its warmed up it should idle without any input from the radio. when it spikes, applying the brakes doesn't slow it down?

it sounds like your to lean, or you have an air leak.

check your fuel lines for holes, make sure the tank isnt cracked, could be the air filter is dirty or to loaded with oil, make sure the carb is tight, and the nipple is tight as well. you can take the carb off and seal it with high temp rtv to make sure it isnt leaking.

also check and make sure the backplate is tight, you can seal it as well with rtv. I've also heard of someone that had a pull start screw that was to long and it messed up the backplate causing an air leak.

is this a new rig or a second hand?
 
It's a brand new rig first time started was today. There might have been the smallest air leak from the carb it had another 1/2 turn left on the tightening bolt till it bottomed out. Other then that i doubt it lean had plenty of smoke and oil from the pipe when i placed the rag to turn it off...who knows maybe it is the lines or the tank.
