I heard somewhere it was a CP125 McCulloch.......
Oh. It was you!
Are there any numbers in castings?
It's not a CP125. It's probably a SP125 or could be a SP105 you
would nead to measure the bore. 2.280 for a 125 and 2.250 for a 105.
Also take those home made rod bolts and toss them into the trash.
That looks like an early SP-125 block. Dealers would get replacement blocks from the factory that didn't have the numbers stamped into them. Sometimes they would even buy unfinished blocks and do the final machining themselves if they wanted different port timing or configuration.
