I've got several WT-349 carbs that just die rather than pick up and run when they go to WOT. It makes no difference how far you crank out the hi needle. I even got some weak needle/seat springs from Scott Brilleli, but no luck. Ive tried these on 25 and 35cc engines, no difference. I hate to throw them away, I've maxed my skill level out at this point.

Ive also got a couple that flood. After you prime them ,they just continue to fill with gas, not good. ANy ideas on what the problem is here? Thanks, flyrc100

Are you try them on a test stand or on a plane build in a cowl?

Engines are on a test stand, Thanks

if it dies when you open up the throttle it is too lean on the bottom end. Richen up the low needle.
Cheers, dave.

if you see almost no effect after opening both needles, you may have dirt somewhere, start removing the needles and clean them up (the seats too)
