Give Ralph a call....if he has a WT71, have him check it over and send it to you. If nothing else, send him your carb and/or entire engine...he'll make it right. He's one of the best in the business, great to talk to, he stands behind his work, and is seriously inexpensive compared to alternatives. It will be worth your time, make the call...
