 Seen this bulletin and thought about those D-19's that were hungary for fuel and wondered if they might have had the big jets in their carbs.

	I suppose it is possible, doesnt say if the wrong jets were wrong large or wrong small. All tractor carbs have jets that are too large and they are restricted via the adjustment needles. We keep our D-19 pretty lean during the summer and winter when we are just knocking around with it and it till uses LOTS of fuel compared to our WD, Plowing? well, dont stray far from a fuel supply. W.K. Rockwell is a name you dont read much about on here and that fact has always suprized me, he was THE man of field service. Edited by Butch(OH) - 19 Mar 2010 at 7:29am
