I do feel the resistance twice per revolution, its just that the resistance seems quite weak. (im also asuming that the difficulty with which i started the motor also had to do with insufficient compression).

From what i could see the piston and bore looked excellent (better than my full crank and my other powertorques which run like a dream), i guess i will pull out the piston and inspect it carefully.

Also, i have not swapped the decompressor around to check if it might be the cause of the low compression (something i guess i should have done earlier).

I will keep everyone updated.

Again, any tip or areas i should look at would be greatly appreciated.
