My 410 will idle fine for about 15 seconds then die. I have tried to increase idle but it dosn't help. I checked the petcock and fuel flow is good. Any ideas?
Delloroto carbs, don't like 10% ethanol gas very much. Really screws up viton on float needle. I'd check that and pilot jet.
Has it been running properly? Might try adjusting the mixture screw first. It walks you through the process here: http://www.mypage.tsn.cc/rdd/TT/contents/CARB/dellorto/dellorto_3_4.html
