ok. i think i mihgt have got a rock or some dirt in my engine. i was tryin to start my savage and i heard it about to start. so i was pull the pull starter and it jus wouldnt start. so i guess it might be flooded. so i take out the glow plug, pull the pull starter a few times, then when i go back to put the glow plug back in, i think i might have knocked a little rock in to where the glow plug should go but I'm not sure of it. so now I'm mad so i put the glow plug in and try to start it again, the pull starter will not move! i can't pull it out one centimeter. can anyone tell me if this could be caused by a rock? cause then again I'm not sure if the rock is even in there. thanks.

Dude pull the head off! and check it befor you do any damage to your mill.
If there is any thing in there and it does start you will have a ruined engine
 
so to pull the head off, jus unscrew the 4 screws at the bottom of the head right? and if i do that i will be able to see inside? thanks
savager
 
Yup, unscew those 4 screws and the heatsink will pop right off and you can see the sleeve and piston.
 
Yep with the head off you will be looking at the top of the P/S when you are ready to reinstall it tighten the bolts in a star patern just like you do when you do 1/1 rim.. I use blue loctite on the screws. do not over tourqe them
 
cool. i got it off, there was a pretty big rock in there, took that out, gave it a courtisy clean, popped it back on, tightened the screws and now the pull start works. thanks guys! gonna go drive me savage now! :tank:

ok now i go to start it, it starts up, then right when it starts, it jus starts revving really high, it doesn't even move the wheels, jus revving, so i stop it, then like i can hear somethin still spinning, so i look and it looks like the black thing that is connected to the flywheel is still spinning. but not the gear that spins the spur. so the only thing that is spinning is the black thing. is that normal when your no hittin the gas? i dont remember ever hearin that before. thanks

Did you take the mill out of your savage?? If so did you reset your gear mesh
 
One thing after another, huh? Sounds like your clutch shoes and/or the spur gear. With the engine off, turn the spur gear and make sure the teeth are in good shape and none are missing/worn down. If the spur gear is good, check the clutch shoes. If those are good, it could be the collet behind the flywheel. At any rate, good luck!
 
nope i didnt take it out. and when i spin my spur gear, all the tires spin and the gear mesh sounds fine. doesn't that mean the mesh is good?

billkalicious, what do you mean check the clutch shoes? what should i be lookin for. i have the 3shoe clutch by the way. thanks
savager
 
Is your clutch bell (the black thing) in mesh with your spur gear?meaning when you spin your spur gear does your clutch bell spin?
 
The clutch shoes are underneath the clutch bell (the black thing). To check those, you'll need to pull the motor, take out the screw holding the clutch bell on and look at what's underneath. They might be worn or broken. You might check ZANDOR's suggestion too about whether or not the clutch bell is spinning when you turn the spur gear.
 
yep the clutch bell spins great. but it only spins one way. i think its only suppost to spin one way though right? and is there a way to chekc the clutch bells without takin the engine out? i jus took the engine out yesterday and its a pain cause i got the rcs cage.
savager
 
No the clutch bell should spin freeley both ways.

did you do any thing to your clutch shoes?
 
nope the last time i drove my savage everythinng was workin fine. all i did before this time was take out the engine, did the dual disk brake and put the engine back in.
savager
 
so when you turn on your raido is your brakes binding? holding it back

take a pieace of printer paper and run a strip in between your cb and slipper
It should be tight in between them
 
I Didnt look through all the posts but, If you are wondering how to tell if you got a good mesh or not, What I do is, Take a finger, Put it on the clutchbell, (Small little gear on engine) make sure it doesn't move, then wiggle the spur gear (big gear on tranny) and see if it moves around like back and forth, but you have to make sure that your finger is tight on the clutchbell, So you can check to see if the gears have moving space in between each other. If it clicks a little, ur fine, but not to much. You'll get used to it man. Also, Whenever before your going to take ur glowplug out, Make sure you spray nitro cleaner inside the engine head, NOT ENGINE, but head, when its bolted down and with the glow plug screwed in, Then spray a short blast, to make sure no dirt is in the head, because if any gets in your engine when the glow plug is out, it will eventually kill the engine and have a very short life. so those are critical procedures to do before working on the mill, especially after running in dirt. I hope i could help.

By the way, I run a 8 Port in my Mugen Buggy.
 
Yah, there should be enough play in the trans and diffs to allow you to spin the clutch bell a bit in both directions. If you can't move it, the clutch shoes are mostlikely the culprit. One or more of them might have broken inside the clutch bell and that could be what is keeping it from moving in both directions. I'm afraid you're gonna have to pull the engine again, just to be sure. Better to be safe and pull it than to have to replace parts on the mill.
 
i jus got home and went to check the mesh by what skyline racer said. if i jus spin the spur, everything works fine. but if i hold the clutch bell, and spin the spur, i can spin the spur both ways. so it was close enough to be movin by itself, but no close enough so have some pressure on it or something like that. lol. but so would that be the over revving? like there was nothing for the engine to spin so it was over revving? thanks for the help.
