Hello,
New member here.
Although I don’t own a Hummer, I do own a Topper And was hoping to tap the brain trust here to help with some information.
I bought this Topper this spring and have struggled with it ever since. I know that it sat for at least 10 years and maybe even 10 years before that owner acquired it.
It only had about 40 lbs. of compression and couldn’t go over 30 MPH. I pulled the head and cylinder to find that one of the ring pins had broken as well as about 1/8” of the end of the ring. The broken ring
end must have caught on the ports of the cylinder and enlarged them. For some reason, I can only upload picture of one damaged port. I had the cylinder bored out to +30 and got a 30 over piston.
My question is this cylinder usable and if so, what would be the effect of the enlarged ports?
Thanks in advance for information.
Barry
