Re: 1951 Johnson rd-11

[opposedtwin]

I have had a number of the early big twins over the years and love them. they run great when they have good compression numbers. if it’s less than 100 lbs, you’ll have trouble getting it to idle well. they’re a bit noisier than the later models like the 1955 and newer ones. take a compression tester with you and check the compression in both cylinders. easy to work on. you’ll love it.
