You have a leak somewhere, contact HPi. Be prepared to have to send it to them. Sucks, I know.
The way you describe the engine not revving crazy until it gets warm sounds like a leak on the engine itself. It could very well just be too lean on the LSN. I have seen it before.
Richen the LSN to try and calm it down. The HSN is not going to slow the idle down on this engine.
 
Do you happen to know the factory setting for the lsn? I'm not down with this "flush" bs that was so wrong with the hsn

also anyone know if this spur gear from tower will work with my savage x 4.6?

That spur will work but you need a hardened steel cb, the factory one is not hardened .You'd be better off to buy the Robinson Racing matched set. Keep in mind, a metal spur will eat the CB if the gear mesh goes out. So instead of a 4 dollar plastic spur, you are out of 40 dollars worth of CB and metal spur gear.
The LSN factory setting is flush. Just richen the LSN until the engine sounds right. If you back it out a lot and it has no effect on the idle speed, you need to find the leak in the engine. A good place to start is the needle O-rings. Remember the LSN controls fuel flow from idle to 1/4 throttle, then the HSN takes over after 1/4 throttle.
 
i would stick with the plastic spur, its designed to be a weak link in the system so if you do break something, its the 4$ spur instead of a trans or something. if you set the mesh and the slipper correctly on the savage the plastic spur will last awhile.
 
Ok y'all convinced me to stick with plastic..

So today I put everything back and filed the spur gear to allow the last bit of teeth to be used until my new ones come in...well as It was idling i noticed there is indeed air building up in the fuel line, as shown, you can't really see them but small air bubbles are vibrating around on the top of the hose there

if it was running and you see bubbles moving your deffinatly sucking air somewhere. check that hose, or the nipple on the tank. the tank has a small hose and filter inside it as well but i dont see how that would have a hole in it.

take the fuel system off, clean it out REALLY good. put the tank and all in a bucket or sink of water deep enough to submerge it all, plug one end of the hose, and blow hard in the other. again make sure you clean it out REALLY good, even the lines, i had nitro shoot back out the lines and in my mouth and eyes before. it burns like hell on the sun with the devil rubbing habanero peppers in your eyes.

watch for bubbles coming out anywhere.
 
i also did my clutch bell on the weekend, mesh was too tight and when it kicked into 3rd gear the whole engine mount dived because it lose a screw on the brace, it just slipped and in a matter of 2-3 seconds the clutch bell had no teeth.

jerry, the integy spur gears are crap. do not use them.

get the SOLID STEEL hpi 5.9 spurs, or the spur with the holes in it, sorry, don't know brand name but it was strong enough to destroy my cb

i got a robinson racing cb and spur. i had the mesh wrong and it SHREDDED my cb in 3 different ways. not even a scratch on the spur though.
 
Yeah its official there are air bubbles passing through the fuel line into the carb. So this is for sure an air leak either in the line it's self or the tank for sure correct? I'm just going to order new line and a new tank if that is the case and not even mess with this one.

can you see where the bubbles start? if its right at the nipple you can try trimming a bit off the end of the fuel line so you have a fresh end.
 
get the fuel tank anyway =) i shattered mine on the weekend. always good to have spares if you get good deals on ebay
 
Just an update, my problem turned out to be a bad fuel line from the factory. The savage tried one last attempt to screw with me, when i installed the line and cruised it it still acted dumb so I was about to call HPI when I noticed that the tank lid wasn't pressed down all the way. I made sure it was down all the other times but didn't even notice it after the line install. Now it's a beast! Today was the first day I got to let it rip, I can't give it WOT at stand still or it will back flip! It will literally just flip right over...just mad power! Never seen power like this before.
