Title: Old Mcculloch
Post by: ktowne030311 on August 08, 2015, 07:01:37 PM
Finally got her together, unfortunately when I had it apart and pulled it over, the wire shocked me and I thought it would suffice. I had the points and coil set to specs. So I put it together and went to fire er up for the first time with no luck.

When I pull it over the wire will shock your finger, but when I put the plug on and try and ground it I get no spark arching on the plug. Anyways I was so frustrated that I set it on the shelf for the time being. Atleast now I know everything else is "solid" and now it's down to an isolated problem. But any who, here's some pictures. There's some.pictures of the "rotary valve intake" which I thought was really cool.

I can't imagine trying to make a living with that but lots of men did. Good job.

Beats a cross cut whip saw by a long shot.
On the spark issue, check your plug wire as it may have a worn spot shorting out at the higher voltages.

Great job! Looks great. Thanks for all the pics, the rotary intake is cool, have not seen one before. Have you tried a different plug as well? Could be something simple like that. Good luck!

Tried a different plug thinking the porcelain was cracked and still no bueno. Atleast it's an isolated problem, and it's sitting on the shelf for one of those rainy days. I have more pictures I took of the tear down, and the rebuild. I'll upload some more later.

This is a very common problem on old engines, cracked insulation allows spark to jump to ground.
