you may not understand portuguese, but you surelly can understand the procedure
details:
- I gentelly removed the vent filter with a drill bit (shall not pass trought), then removed the duckbill rubber valve
- I putted a 6,5mm tube on the hole
- tried silicone but it didn't work
- putted epox glue and this time it sealed and fixed the tube to not disatatch
- the new check valve (on top of the tube) wasn't dimensioned for this machine so it didn't suck enough air with the valve cap on... I cutted a second gap on the cup and on the internal part of the cap, than the air flow match the engine needs
problem solved
