While I haven't had to hand crank my DV20 out of necessity as yet, I have been trying to hand start it just to prove I can. As yet I have had no success. Does anyone have any tips.
Thanks

Not familiar with the engine, but does it have a decompressor, and if so are you using it?

Yes, I am decompressing the motor. I have been cranking the motor as fast as possible then releasing the decompression lever. All that happens is the engine just stops dead. I'm sure there must be a trick but I haven't found it yet.

The answer is to start it on one cylinder as it's unlikely (unless you're Geoff Capes) you'll be able to overcome the compression of both cylinders.
Disconnect the metal tie-bar linking the two decomp levers together, hold or tie one in the decompression position (SWMBO does it on our boat), hold the other on decomp and build up the cranking speed. Flick in the lever and the engine should fire up on the one cylinder.
The engine will run perfectly ok on one, so you can flick the other lever on when you like within reason.
Worked every time on my twenty, but am dreading having to try it on my new 24hp Bukh. Bukh TELL me this version starts much more easily as it's direct-injection - I just hope they're right!! /forums/images/graemlins/frown.gif

[/ QUOTE ]Well my 20yo (I know, it is still a "new" one and being run-in) dv24 starts fine on the handle (can't seperate the decomp linkage) but I find giving her about 1/4 throttle, or maybe a bit less, does the trick. Seems to overcome the auto timing "adjusting" itself on startup - by default the DV24 starts on full throttle then cuts back to tickover but by manually opening the throttle the pump cannot cut the fuel back as far. /forums/images/graemlins/grin.gif

for safety, wind the crank with thumb *not* grasped around the handle ie as though you have no thumb. Otherwise if the thing kicks back when you flick the decompression lever you might actually end up with no thumb...

How many thumbs have you got? I have two but counted at least three in your advice.
