Before you start your Seagull for the first time...

Post by Guest »

First you need to do a physical inspection...
  1. Is it all there?
  2. Is there anything broken or bent?
  3. Is there a lead to the sparkplug from the Magneto (the round thing on top)?
  4. Is there a throttle cable from throttle lever on tiller handle to carburettor?
  5. Does the throttle lever move back and forth?
  6. Does the magneto (flywheel) turn around without scraping noise?
  7. Is there compression (resistance whilst turning flywheel)?
  8. Does the propeller turn when flywheel is rotated?
  9. Does it have a dog clutch (i.e. a lever that goes up and down attached to a rod that attaches to the gearbox which the propeller is attached to)?
  10. Check there is lubricant in gearbox. The gearbox drain plug is at opposite end of gearbox where propeller is (older models have nipples and need disassembly to check).
  11. Is the tank, fuel line and filters (2 of) clean?

All good so far? Great! Now use the SOS Serial Number Identifier to see what fuel/oil mixture you will need...
  • Make sure you add fresh fuel with 10/1 two stroke oil (or 25/1 in some later cases)?
  • Install a new D16 Champion sparkplug.
If all is well, it is almost ready to start...
  • Place in test tank (wheely bin etc).
  • Add water a few inches above gearbox housing.
  • Undo blead screw on tank filler (lets air in as petrol is used).
  • Pull fuel knob out at fuel tap at base of petrol tank. Expect petrol to drip out everywhere. Keep fire extinguisher handy and test in a flame free zone.
  • Open throttle to about half (each motor has a unique starting position).
  • Push choke lever (metal flap on Carburettor to reduce air intake) down.
  • Push down small button on carburettor until fuel spills from a small hole, release.
  • Wind rope around top of flywheel pulley. Knot goes into insert.
  • [i][a diagram showing the highlighted words above could go in here][/i]
Pray to Thor, kiss your Sheila good bye and let her know where the will is...
  • Grip the tiller with one hand and evenly pull the rope with the other. Nothing? Do it again. Expect to try two or three times for a functioning motor.
  • Once started, check to see if water is coming out of tell tale.
  • If all is well, lift choke lever slowly as motor warms up. Play with throttle. If it has a clutch move lever up and down at just above idle speed. Never use full revs if the propeller is removed or clutch is disengaged.
Now that she is a working motor you can get into a more advanced mode and check points gaps etc...
