Hi all,
Back with a new question to the group...
Just trouble shooting some small problems with the px... nothing serious but waiting for a few parts to update the engine, before carrying out with jetting the pwk airstriker...
But I found that as I'm testing the vespa, I'm actually getting quite a bit of blowback through the carb, I didn't think about it too much before, but isn't the Reed valve suppose to get rid of the blowback?
Wonder if anyone has any insights on potential reasons? I checked the Reed petals... no gap, chips or broken parts
Just for FYI, It's happening at 1/4-1/2 throttle
