Default Make pull start easier?

My 1955 15HP Evinrude is a bear to pull start. Is there any way to make it easier? I'm bushed before I cast a line!

Remove the recoil and look at the sheave, is it round where the rope winds? The later motors used an oblong sheave and a pawl that was timed to catch when the engine was coming up on compression. This gave leverage to pull over compression and speed as it came off of compression, making it a steady easier pull. I don't know if this would be adaptable to your motor, would require the recoil and flywheel.

Any ideas on where to find out if this would work on my 55? where to get parts,? etc.
thanks for the idea.

Make sure the mag is good and strong, points are clean and gapped right, etc. Carb is set right, fuel fresh, on and on. If anything is a bit off your arm gets to compensate....

My 55 Evinrude runs like a top, once I get it running. The problem is that it is hard to pull. I won't be paying $50.00 to ask my question. Thanks anyway for the tip.

Two methods come to mind. Easiest is to add longer pull rope if there is room. As the rope is wound on the recoil, it increases ratio and thus the leverage on the first part of the pull.

The second is a modification of the valves, that you may not want to do.

Before the trick of a moving pall compression release on the cam, Briggs & Stratton used to grind a nick on one edge of their exhaust valves that served as a compression release, but only had minor effect upon engine performance at higher RPM. Perhaps too drastic to try on a good running engine. But maybe something to consider if you could obtain an extra valve to compare performance effects with. I only saw the nicked valve trick used on small one cylinder engines.
