    Status: offline     		So you see all three I'm talking about then?

    I may be calling it the LSN incorrectly, but it does control how the engine reacts on the low end. It's also shorter to abbreviate LSN

    They shouldn't call that one the idle adjusting mixing screw. the idle adj. should be the one directly below the filter.

    I can tell you for sure the one on the flange affects the first 1/2 of acceleration and if it's too rich it will be blubbery and want to choke to death (and yes about 1 1/2 or so to start). The HSN is the main one and affects the 2nd half of the throttle. If it's rich similar thing only at the top end.

    I had issues at first with both and was able to correct it with this approach so I'm sure it is correct. The directions are BAD if you've never had a nitro before. I'll take better pics tomorrow to show you if you need.

    Let me know if it helps it

    Status: offline     		It is called the correct name because it is the idle mixture screw. The idle screw controls the rpm's and the idle mixture screw contols the fuel/air mixture at idle - 50 %.

    Status: offline     		hey c.d. - no offense taken. Just wanted to specify so if anyone was reading back in threads and had seen LSN they would know it is also (or is) referred to as the idle mixture screw.

    Guys - have I said lately that I love this buggy? This thing is an absolute blast. I got the software going and I will get some video together soon. I'm redoing my bathroom so it may be a week or so before I have time.

    Status: offline     		Got mine out to the track again today. Man I love this car!!! Now if I can just learn to jump. I am used to going in circles and on pavement.

    Anyway I had it running about 270* and it was loading up on the bottom end, rich. I tried messing with the screw on the left of the carb (from rear of car) and I really messed it up. I enlisted the help of a guy that really had his car running well. He came over and looked at it and said "Hmmmm, 3 needle carb, don't know about this..." I talked him into helping. After looking into the carb we decided to adjust the other screw, the one that moves WITH THE THROTTLE for the low end setting.

    I return the screw I messed with to the place I started. We fire it up and take it out. It dies, in about 1/16 on the lowend screw. Start her back up and out we go, better. But still loading up and only 210*. We adjust the high end a little and a little on the lowend. Better but still a little stubborn. One more time out and BINGO!!! 240* and plenty of bottome end.

    Now if I can get them to get rid of those dang jumps!!!

    Status: offline     		Scott - I was having issues with jumps until I adjusted the shocks. I let the back ones all the way up (full softness) and tightened down the front ones by about 1/2 inch. Now it has good spring on the front and I think it helps to spring up the nose before take off.

    Give it a whirl. I have been jumping great ever since.

    Status: offline     		Hi , im new to all this and it is my first ever post.

    I have a 1/8th scale bazooka and it is the best thing i have ever had. I have flipped it many times and drove off with no probs. I have only broken a tooth off the main gear and i went to a hobby shop and got a new one there and than. Some unknown nitro`s are hard for parts but the bazooka is the best for money and it is a really strong build. Starts eaisily and always.

    The reason it broke the tooth was bacause the motor was not close enough so the gears didnt mash properly so anyone bying a new one chack before u drive it. I have already lost a wheel nut but was lucky enough to find it again. tuning has been a pain in the ....... prob cause this is my first one. it will run fine than it wont, im not sure exactly what needle does what, i have a rough idea but just wondering if anyone could give a detailed description

    Status: offline     		Hey Synergism - not sure about the set screw. I haven't messed with it but that sounds more like personal preference (if you are asking should you have it drive more on the front when possible).

    Hey Porter - Good to have you! So when you went to get a new main gear - which part did you buy (for a Kyosho etc). Any parts you've mixed and matched would be good for others to hear about.

    On the tuning - being new is probably most of why it is tough. You really just have to get a feel for it. And also try to adjust one thing at a time so you can see how it affects it.

    There are some other posts here and there about it - so definitly skim through but once again the Low Speed Adj is on the throttle flange. The screw opposite this screw should not be moved. THe LS affects acceleration. If it is dying on you when you begin hitting throttle it's to rich or too lean

    The HSN affects from about 1/2 acceleration and on. If it wants to cut out on you then that needle is too rich or too lean. You have to have them each close to begin with though or it will make it tough to figure anything out.

    For my engine and weather I have mine set at about 1 3/4 turns on the LS and 3 turns on the HS for a starting point.

    The idle screw just does the idle. Should be barely open. Also - the idle (or amount of opening in the carb when you look in) should NOT change from idle posistion to when you hit the break. If it closes off when you hit the break you don't have your servo centered. And trust me, you don't want to have your break on all the time to keep your car still or you will go through clutch shoes

    Status: offline     		My 1/8 buggy has a set screw that seems to adjust the slip between front and rear. What is the center unit called? How should it be set?
