I was just wondering how many of you have eliminated the hot water line thru the carbs and the return line on the other side of the motor. With what results? I live in Oregon so it gets a little cold in the winter. I have a new motor put together and noticed after I put the manifold and everything:angry: on that the exit hole on the back was plugged because the threads were broken off internally. I guess I could take them out with an easy out, but I know that some people just eliminate the line and was just wondering what they thought. It would be an easier solution for sure .

Any thoughts? Thanks in advance John

John,

Since 1988 and about a half a million miles of daily driving with unheated hitachi carbs I had ONE instance where the temps were low enough and the humidity was hiogh enough for the carbs to ice up. Coming down I-5 by Longview. By the time I got the hood up in Kelso and looked, the ice had melted from engine heat and off I went.

I would worry more about that shakey plumbing leaving you standing beside the road from leaks.

Thanks Bruce. Dave Irwin rebuilt these so I will make and plug the holes correctly. Thanks again.
