How you set your propeller in relation to the engine compression stroke is entirely up to you. For those that hand start their engines, a blade position close to a two o'clock and eight o'clock position works very well. Again, propeller positioning is completely up to the user. The only time propeller position becomes critical to starting is when a magneto is used for an ignition system. With electronic ignition systems propeller position is not important at all.
Makes sense. Also the 2 o'clock position seems to help props stop in an angle where the blades (2 blade props only, and if they are stopped.) are horizontal saving props from the damages caused by a bad landing or faulty landing gear.
T.O.M, thanks for the prop article. It was very helpful. Although I have been convinced multi bolt is the way to go, I can also see it can easily ruin your props, too, even with a drill press. The wood grain can play games with your otherwise straight drill bits.
Piston,
- Re: 26 cc Mounting Template
The vertical distance between the mounting holes in the 26 cc templates say 49 mm. The users' manual says it's 50 mm. I measured my 26 and found it's closer to 50 mm than 49 mm. I'm not 100% convinced my measurement is correct. I used a caliper and measured several times. I don't have a good center hole locater.
The drawing mention carburetor outline, but it seems missing. Is it incomplete? The carburetor outline will be very helpful.
Best Regards.
