I just bought a cheap engine kit off ebay with the following specs:
I know I can't really trust the specs, but I'm curious about the 7.8:1 compression ratio that is listed.
Does this make sense for a 40mm stroke engine with the stock slant head?
Any guesses what engine I'm going to get?
The power rating claimed looks low (or honest?) for a 69cc @ 6000 rpm.
Please, speculate for me, and when I get it, I'll tear it down and see what it is.
