yamaha 100 tilt down motor shuts off

[flintstone]

i have a yamaha 100 that i had the tilt piston
replaced now the engine will not run when in
the down position it will start and run great untill i tilt it down
to a certian point then it shuts off. the shop that did it
will be closed for a week any ideas on what to look for
or where? i never had this problem before
and am hoping its something easy thanks for any help

all my best from florida
