I see no way that could occur.

BTW - I've had Grose jets on the TR3A for 30+ years -- one did stick closed
once after a long sit years ago, otherwise no issues.  I'm not recommending
them, just saying they are not always a problem.

No harm in replacing them, but my guess is that you have an ignition
problem and will still get the miss after the change.

Sometimes ignition components fail completely but I have known some to only
fail once they warmed up (thinking of coil & condenser here).
