I am truly sorry to see Uncle Dan D get such bad ink.I absolutely will not try and say you didn't see what you saw, or get (or didn't get)what you got.
Dan taught me some very valuable lessons many years ago about engines, and spent a lot of time with me on the phone long long before I ever bought anything from him.
My 500" siamese bore alloy headed motor may have cost me a little more than we discussed,but it was real close to what we agreed on.He got paid and shipped the motor.No BS.There was waaay less smooth talk and snake oil on that 10K build
than my last 2500 dollar flower planter from Oregon City.
I got what I paid for from Dan D.
Sorry it went sour for others.Really.
