Grune Posted April 6, 2005 Share Posted April 6, 2005 (edited) hi, i just bought a savage 25. My truck is completely stock. I read the instructions for the run in and got it started no problem on a block with the wheels off the ground. The thing is the wheels are running quite fast and it should be in the idle position. If i try to use the brake control or just pull the throttle back a little it slows and cuts out. But wont idle, or run slowly as the manual states for run in. I diddent want to alter the settings as the manual says not to till after the run in. I have ceased my run in till i can get some advice as i dont want to damage the engine. Any help would be great thanks. Edited April 6, 2005 by Grune Quote Link to comment Share on other sites More sharing options...
LEE69 Posted April 6, 2005 Share Posted April 6, 2005 turn the idle screw down a bit,closing the carb gap down,thus slowing the tickover. Quote Link to comment Share on other sites More sharing options...
madmanluke Posted April 6, 2005 Share Posted April 6, 2005 dont touch the idle screw untill youv compleatly run the truck in and tuned. it will just screw every thing up later on. Ie more harder to tune. it shouldnt matter how fast the wheels are spinning. just try to get it in a nice steady idle. as long as it doesnt sound like its going at half throttle youl be ok.

Grune Posted April 6, 2005 Author Share Posted April 6, 2005 i dont think its going too fast as the throttle is only open a little bit. Could the wheels be going fast because they are completely off the ground? Quote Link to comment Share on other sites More sharing options...
madmanluke Posted April 6, 2005 Share Posted April 6, 2005 it shouldntmatter how fast thw whells are spinning, as long as the throttle is as low as you can get it with it cutting out and is stready, your fine. As the wheels are off the ground this is probably why they are going fast. mine were slow to start with but as the engine began to hewat up, thw wheel got faster, i left it alone as the engine was still at a low idle.

300ZXZ31 Posted April 7, 2005 Share Posted April 7, 2005 no phil thats the idea you adjust the carb with you hand. Quote Link to comment Share on other sites More sharing options...
madmanluke Posted April 7, 2005 Share Posted April 7, 2005 wrong, it doesnt matter how fast the wheels go, its how fast the engine is ticking over during break in. It shouldnt matter if you have the radio gear on at the same time as you can fine tune how fast the engine is running at idle. the wheels may only be spinning fast due to the gearig you have. it doesnt matter how fast the wheels are spinnig, just ow fast theengine is ticking over.

300ZXZ31 Posted April 7, 2005 Share Posted April 7, 2005 well the faster the engine go's the wheels are going to get faster as well arnt they. so if the wheels are spinning more than just gently rolling the engine is going to fast. Quote Link to comment Share on other sites More sharing options...
madmanluke Posted April 7, 2005 Share Posted April 7, 2005 not nessasarly, the clutch will always be slightly engaged whilst of the floor, as long as you can get the idle down as much as you can you dont need to worry about any thing.

Grune Posted April 8, 2005 Author Share Posted April 8, 2005 The carb is open about 1mm with the situation a mentioned. A couple of people mentioned that the clutch shoes may not be seated right and it could explain the fast running of the wheels. Any thoughts on that? cheers Quote Link to comment Share on other sites More sharing options...
Monstrous Posted April 8, 2005 Share Posted April 8, 2005 (edited) take your clutchbell off and check the clutch shoes and the little springs they sit on, coz if the springs are knackered then the clutch will engage too early and consiquently leave the wheels spinning too fast at tick over Monstrous Edited April 8, 2005 by Monstrous Quote Link to comment Share on other sites More sharing options...
007_boyracer Posted April 8, 2005 Share Posted April 8, 2005 dude! turn your radio gear on! if it picks up interefere it'll just rev its nuts off the throttle wont stay at the idel position once u turn the radio off! also ignore the wheels what you need to watch is the gear's the little gear coming off the engine and the larger plastic gear shud be just spinning (if u dnt let the two gear spin slightly u will simply burn out a clutch) tweak the running rpm with the throttle 'trim' on your radio gear but make sure them gears are spinning thanks lee Quote Link to comment Share on other sites More sharing options...
madmanluke Posted April 8, 2005 Share Posted April 8, 2005 this is the point, you need your radio gear of just as a precaution incase there was any interferance. have the stuff of would iliminate the chances of getting this. Quote Link to comment Share on other sites More sharing options...
300ZXZ31 Posted April 8, 2005 Share Posted April 8, 2005 if the batts arnt plugged in though nothing will happen if there is interfearnce Quote Link to comment Share on other sites More sharing options...
007_boyracer Posted April 8, 2005 Share Posted April 8, 2005 no it wnt be it also wnt be idling where the radio is set up for it to.... dnt forget the spring on them you will find the vibration when running will cause the carb to open slightly....

Grune Posted April 8, 2005 Author Share Posted April 8, 2005 I have just been trying out the radio throttle control and brake, without the engine running and was worried about what happened. if you apply the brake even a little, when it returns to nutrel it opens the carb up a little more than it was to start with. If the engine where running it would give it quick a boost of acceleration. I tryed loosening the screw where the throttle/brake joins at the servo, but it did no good. its too cold to do anything outside tonight so im going to check the clutch shoes.

007_boyracer Posted April 8, 2005 Share Posted April 8, 2005 thts nothing do with clutch shoes mate hold the brake on so the carb is pulled to and tighten the little black screw with a spring on till u feel resistence (dnt go mad) then release the brake and the car SHOULD stay where it was Quote Link to comment Share on other sites More sharing options...
J C Posted April 8, 2005 Share Posted April 8, 2005 Thats to do with the linkage, you must have changed something. Quote Link to comment Share on other sites More sharing options...
Grune Posted April 8, 2005 Author Share Posted April 8, 2005 (edited) I know it have nothing to do with the clutch, but it was suggested the fast wheels may be due to the clutch shoes not seated right, but that fine.
