new to forums..just a question about refilling- I'm new to refilling butane lighters.

I followed a youtube video instruction- pushing the valve to release whatever air out first, then pumping the butane canister a few times into the lighter.

My jet lite lights up again..but only on high. On low, it won't light up & I'm certain it maintained a smaller flame on low when it was new. Is this normal?

Is this a sign I haven't filled it full? (when it was getting close to low..i noticed that it wouldn't light on low but still lit on high).

I've purged & tried refilling a few times now with the same result.

Just curious..thanks.
