Might have an engine issue.

“51 Willys jeep for sale. Body, frame and interior in great shape. Original drivetrain with flathead 4 and t90 3speed. Engine will need work. Has no compression so believe rings are needed. Ran when I got it but weak. Drove it for a couple times and got worse. Was going to make into a river jeep but in too good of shape for me to do that. Brakes and turn signals work. Guy I bought it from drove it to work everyday. Still has foot start on floor. I think I have a bikini top for it. Will check for sure. Asking $3500. Clear title”
