Well, I have ran a second ground to the engine block and then after no success ran a new hot lead directly to the starter high current terminal. No success.
I opened the the decompression lever while the wife turned the key and she spins and if I drop it back to normal mode while the engine is spinning, it starts. The old manual that I located on the web indicated that this was the way to start the engine...Lol... My guess is that my starter may be weak but certainly it gets a work out turning that engine over. The decompression lever has the ability to have a remote cable attached which I plan to do so that I don't get stuck somewhere.
What are you guys using for oil for this engine?
