Thanks Jon; I will heed your advice if possible. On the other hand I am high bidder on a new YF6420 reman on ebay for $5 plus $15.00 S&H. For $20 bucks I'll give it a try. If I don't like it, I'll add it to the ever growing carb collection under my work bench

And then move on to one of the models you listed.
