  1. The mixture screw adjusts the air (next to the tickover screw} There is a screw on the other side (brass) is a pilot jet only fitted on premier carbs I use this carb on my cub
  2. The brass insert where the needle goes through the ventury are different One is square at the top the other is cut away I use the the premier type on my cub The body uses a better alloy and the slide is coated
  3. To replay to your query Trials are up dated all the time They started as reliability test Inthe SSDT observed hills started cica 1920 The first loss of marks for footing was round about 1930 When I started trials marks were 0135 later to 01235 on single route section Things have moved on multi routes stopping allowed as have the bikes

    Cub

    I have two cubs one uses Electrix world mounted on the outer clutch case The other mounted on pillars fitted to the crank case The first one is a little tricky to set up But both work fine I have used the PVL system also mounted on the pillar
  6. I have two cubs One swinging arm I am unsure of sorce The other came from FEKED A cub one the tubes come from the pivet points at an angle and bend straight half way down The FEKED the tubes are straight all the way and sit outboard of the pivit points to allow the 400 tyre to fit
  7. I run my cub with the standard cam as I found it harder to start and if going over a ridge where you shut off it would stall I built the engine in a verity of specs High comp pistons low comp pistons with and without the R cam I run high comp piston standard cam If can climb Scottish hills it is fine
  8. You are correct down is on The lever is usually marked with a C and R closed and reserve
  9. The cub I own has done three years running with no seals fitted with out problems A little oil down the valve guide can stop wear or seizure of the valve
  10. Set points to the correct gap The spark will occur at the point when the points start to open This is 2.5 mm BFTDC if too advanced the engine will kick back and run in backwards Set up a lot of points been in the motor trade a long time so set a lot in my time Still run my Bulto on points
  11. You do not say witch carb you are using I use an AMAL concentric on both cubs Both engines are move to the left One uses the cub manifold Yes the cable clears the frame but only just The other has a made up manifold that makes the carb more upright and is much longer and has more of an offset
  12. You still have a bit to go I stopped competing at 68 ( was taking longer to get over the pains ) but use one of my off road bike to get round to take pictures Even used a cub at the last club trial ( taking pics)
  13. My sherpa t is a 221 but is a 175 ?Had it since new but never had the head off but done a lot of work So are they 125 or 175 !!
  14. My hand book for the TL 125 only shows the ignition Generator Black /white wire out up to a joint Green to kill switch black/white to double connector One to the contact breaker the other to the coil and condenser Generator and kill switch are earthed
  15. That is the gear the sliding gear dogs on the lay shaft lock in to so if it is slack it will jump out Is the gear or dogs worn ?
