Having problems with my late model B75.. This unit sat for long time unused so I disassembled carb for cleaning... This was spotless inside.. Checked all jets and float operation... All seems ok... When I start it with choke, it runs about 10 seconds then stalls... If I have it started and then remove choke it seems to stall even quicker... The float bowl always seems to have fuel since there is a drain valve to check this.. (I believe this suggests the fuel pump and float needle are working?)<br /><br />Can anyone suggest anything... The carb seemed clean yet I wasn't able to get to the drilled passages..<br /><br />I tried to order feul pump diaphrams and float needle just as a precaution but apparently these parts are discontinued??? (price had they been available = $86 and $29 respectively) WOW.<br /><br />Any suggestions for troubleshooting and can parts be crossreferenced from other after market brands?<br /><br />thanks..
