I'm a 3 day old nitro owner, so forgive me if this is a simple question,

I have a new savage. I think its pretty well dialed in except, it is very very slow when it starts from a stop, it seems it needs a little push then it runs fine. I tried to lean out the low speed needle with no progress.

Any advise would be greatly appreciated.

when you hit the throttle real fast does it bog down and then kinda like catch up once its going?

what if you hit the throttle slowly ? does it move along fine?

Man I'm kinda having the same problem.

Mine runs fine now but the HSN is actually pretty lean.

But still it kinda bogs down at the top end.

My HSN is like 1.5 turns IN from what ppl normally run for my engine. I dont get it!

Then again I'm still breaking it in, and my fuel has 18% oil so that may have something to do with it.

I'm trying to keep the temp at around 240 after a high speed run.

Mine isnt that bad, but one thing is for sure. My needle settings are way off from what ppl run.

Leave your low speed needle where it is set at, and richen your high speed needle. This should make your SAVAGE peel out on the dirt. Also increase your idle slitely.

Your LSN is what controls your throttle response at take-off.
If you are having a problem accelerating from idle then you need to adjust your LSN.
If it accelerates fine from stand still and then when it's coming up to speed it bogs down then you need to adjust your HSN.

True that the low speed needle controls your low end acceleration, but if it is leaned, and your high speed needle is also leaned out your acceleration will suck because the carb is not getting enough fuel from the high speed needle being leaned out also. This is why leave the leaned out setting on the low speed, and richen the high speed needle. Try it young grasshopper you will see what I am talking about.

From my experience the LSN is what helps out a lot, unless you've been messing aroudn with the idle. If your throttle acceleration is slow it might be that you are running it to rich, so adjust it by going clockwise. Lean it out a bit not too much though. If you get a fast take off than it boggles turn you HSN counter clockwise. Most of the time though it seems that people have been running the LSN to rich though:/

Maybe it's not your needles.You said when you hit the gas the truck revs then takes off right?So maybe it's a clutch problem or that one-way bearing in the tranny everyone complains about?

I agree it sounds more like a slipping clutch in my opinion. clean any oil greas and junk out of the clutch to be sure its not that.

Where in the chacago suburbs are you at? I'm in the NW burbs and bash with several people in the area.

I'm in St Charles.

it was my LSN I was way to rich, and to lean on my HSN. Now it runs great. except i'm having trouble trying to get it to switch into second gear. I've already adjust the gearshift 180 degrees counterclockwise. not sure how much more i can go. It just whines out and the guy at the LHS was helping me, then my pullstart broke so i thought. cord would not retract, So took engine out, loosened one hex nut on the pull starter to take it off, and the cord retracted. must of just got hung up. So now i have a spare pull start.

How many tanks do you have thru it? You probably won't notice much shifting until about the 8th or 9th tank... if you're past that point then keep turning in about 1/4 turn increments, if you're not to the 9th tank yet, keep running!

Sounds like a slipper clutch problem. Maybe a clutch shoe problem, but unlikely. Take a couple full throttle runs from a stop and bring it in. Feel the slipper and spur gear, if its good and hot the slipper is slipping too much. Tighten it down all the way and back off 1/8 to 1/4 turn.

I have about 8 tanks in. But only 1 where the needles were set right, i was running way to rich, so now i finally have some go to the truck. With running so rich tanks of fuel didn't last to long, so i'll run a few more tanks, then try to readjust if needed.

I will also check the clutch.

Thanks again everyone
