Doesn't it always? FWIW, I DID get it runnin and drivin. I drove it back and forth to work everyday round trip right at 20 miles for just about three months. It's still pullin on me not to mess with it. I am acquiring all the parts to put "somethin else" in it, but it still may not happen. The little 170 runs so good. Same scenario as my F250. I have a warmed up Ford 400 under the work bench. I could swap it out in a Saturday afternoon.....but the DEADGUM 351M runs so flawless and has GOOD POWER and is FUN to drive, so I just keep drivin it. lol
