Hey guys I just purchased the DL 50 and it has been a while since I have used a gas engine and have a few questions. I need to know where to set the piston / prop for starting and some tips on how to mark the prop / backplate so that I can drill them with the prop drill jig.
Thanks
Jeff
I have found that the best position to drill is to turn the prop facing you(forward) placing the prop on a horizontal plane. set the drill jig with one hole to the 1
o clock position. drill from the front first, reverse the drill jig to the rear and then drill through from the back to true the holes. when putting the prop on the plane, set it as to compression comming to the 1:00 clock position. Ths will best insure fingers are clear on the downward swing of the prop.
With the prop just drill the 4 holes square with the prop. In other words, the holes form a square that 2 sides are parallel to the length of the prop. Or if that doesn't make sense, with the prop held in front of you with the tips pointing directly up and down (12 and 6 o'clock)....holes are at 2, 4, 8, and 10 o'clock. If you do this the prop tips will be at about 1 and 7 o'clock just starting the compression stroke.
With the spinner back plate it doesn't matter since the spinner cone slips on it to where the prop goes through. Just put the jig on a drill them.
Backplate doesn't matter where you drill the holes.
Whups forgot I had a picture.
