Do I need to re-jet my Thermoquad?

The large difference in MJ sizes is accompanied by changes to the air bleed size, to keep the a/f ratio correct.
I am preparing a Ford 800 TQ for an engine, & it came with 101 MJs. Sounds big but so are the air bleeds.
Not sure why the change to bigger jets was made over the years. If I had to guess: bigger air bleeds, adds more air, creates a better atomised mixture for reduced emissions; bigger ABs need bigger jets.
Going from 092 to 098 is a HUGE increase. Try a 095.
