    Mark, absolutely no shame – huh. Why not $1000?

    William. Make sure the air gap between the sprocket halves are equal. Try to use a thumb to hold down the sprocket half firmly on the sprocket carrier as you tighten the Center bolt. Make sure your sprocket half spans the split in the sprocket carrier and does not line up with it. Make sure your sprocket carrier is true as far as left to right runout. If not don’t throw it out have a friend with a lathe use a piece of an old 50mm axle and take a few thousandths off until true. If you don’t take the clutch apart to clean it , at least spray brake parts cleaner in the drum area (use the tube so you can direct it better) to remove the dust. When you’re done with the brake parts cleaner don’t forget to use some white lithium grease on the roller bearing. You really should do this before each session, but don’t go crazy with the white lithium grease, it only takes a little bit. Just two small squirts directed between the mount bolt and the drive sprocket. Make sure to use the tube that comes with the grease.  We race the 401 also runs nice. Good luck.

    I guess time can be an issue, but the proof is in a leak down test. Simply put the most can be gained in the 206 with a good sealing valve. In KPX we lap valves every 2-3 races. Many times if the engine is apart already every race. I admit that to be excessive. At club level lapping the valves at half season should keep you very competitive. It may be that your driving skills and Kart setup skills can help much more than the focus on the engine. At higher level where everyone is fine tuning their karts, every three races max. The courts out on the valve springs and different engine builders/ mechanics have there own opinion on that. I think replace at half season.

    Hi William, now that the season is over I may have some help for you, all be it a little late. I have a little experience with the 206 and can tell you a few things that may help.

    You can read the plug easily just use a new plug to get accurate info. The boot does matter and is definitely an important part. Yes it can produce an air leak. The low speed jet is so small make sure it is clean and clear. A sonic cleaner works very good with distilled water and a mild water based cleaner. The needle is for low to mid and does not “cross over” to the high speed system. Although the needle can be an indicator as to the direction you may want to go on the high speed. Now for the high speed – remove the carb and remove the bowl. With the carb upside down measure from the lip of the body going around the float to the top of the float. Using a caliper set it to .87 inch. Make sure both sides are measuring the same and are not uneven. High speed can be adjusted by the float setting. Yes it works. Short tracks and rich setting at about .83  to .84 and lean setting to .92 to .93 – keep in mind the carb is upside down. Basically you are starving the engine slightly with a low (right side up) float setting.  The engine loves to be lean on the top end, but if course there is a limit. Short straights and short twisty tracks on the richer side maybe like Davis. Longer straights and faster track leaner like Sonoma or maybe Atwater( Atwater being a compromise between the long straight and the slow tight corners) In conjunction with precise valve settings a fair amount can be gained. Also make sure the air needle adjustment is about 1-1/2 turns to start out with. Remember that it lets air in, the further out the more air is entering the low speed system. The needle in position 3 – numbered from the top of the needle with the top being #1 so  #3 is in the middle. Experiment and learn.  You may private message me and I can help a little more or clarify what I write. By the way, I have never had an idle issue in the 3-4 years my son and I have raced the 206.

    Very common to us. Low speed jet is plugged. Clean with small wire or a micro drill bit very carefully. That jet is a tech item so don’t enlarge it. Referring to #40 low speed jet. Drain the fuel after each race day. We have an appropriate sized micro bit and an extra jet and as a matter of course change or clean it every morning before racing.

    WOW!! I’m more of a problem solver. I like what Gary Lawson has said. Offset the darn thing!! I use a ton of offset on my OTK racer chassis and haven’t had one problem yet! I also offset the seat to the drivers left about 15mm and can set the chassis up to slay the competition. We ran the Syd White Memorial race this year and won in senior WF ( same block and footprint as the LO206) some of the last few laps were as fast as the first few. Just tonight Iwas arguing about the offset on a 2014 EVK Racer with my son. We need to offset it an additional 3/8″ over the EVRR and another EVR we built. I’ve built 4 OTK racers so far and all regularly occupy the podium at our track. These are not gimme races we race against the Agan family and Tyler has been running four cycles for over 11 years. He’s a national champion and one tough competitor. Go kart racing is a battle of solutions. It’s not just driving as you’ve found out. Setup (initial assembly) strategy and driving. Maybe more respect for the guys that look at the problem, solve it and go on to figure out how to win! Come on man — step up– if for nothing else your sons respect in persevering. Not everything in racing is “bolt on” or parts hanging.

    Taavi, yes and possibly no. I would deal with Italian motors. Why make life difficult for yourself. Italkarts and the alpha use the same components and Michael is very sharp with the vintage you need. The Componet  shown probably has the wrong kingpin inclination. Ph2   Again look and see if you have no dots on the top of the spindle, one dot or two dots. It’s a depression in the top right before the bolt section. Just call Michael and take advantage of his experience. Save yourself trouble

    Almost certain it came off an alpha kart. I use to sell them. Call John at Fastech. I think his site is Fastech-racing. Com. Vintage is about 2001 to maybe 2004. Italkart stuff should work fine. He handles Italkart stuff. See if there is a dot on the top of the spindle right before the bolt. There is either no dot , one dot or two dot. Denotes inclination of the king pin. Just match that up and you should be fine.
