Managing a 1-1 draw through East last weekend has bookmakers favouring the Glasgow side to come good at the second time of asking, however experienced striker Scobie reckons he and his team-mates cannot take a place in the third-round hat for granted.
The 31-year-old admitted: "There's no doubt if we go out and play like we did in the first game then Stoneyburn will probably beat us.
"We were downright awful and struggled for long spells on a very iffy playing surface and it says everything that the gaffer Brian Heron deemed big Andy Banks the only outfield player worthy of pass marks for his display.
"I had a horror show myself, capped by missing an absolute sitter at 1-1, and the only positive is we are still in the cup with an opportunity to show we're capable of playing a whole lot better than last week.
"If everyone raises their game – myself included – then I'm fairly confident of making it into next Tuesday's draw, but not overly so because Stoneyburn have some decent players of their own and will fancy their chances of getting a result."
Scobie is still finding his Lochburn Park feet after almost a year out of action with a broken leg, however he looks a racing certainty to get the nod from gaffer Heron, whose forward-line choices are somewhat limited with Alan Orr rated extremely doubtful and the pacey Jasper Donnelly on the recovery trail following a month-long absence due to a debilitating groin strain.
Hill boss Heron echoed Scobie's caution and urged his playing charges to put graft before craft when looking forward to the Lochburn Park clash.
He said: "Barry Jones twice came close to giving us the lead against Stoneyburn and an early goal might have allowed us to settle into our normal game.
"But to give credit where credit's due, their response was to get in among us in showing they have a bit of belief about themselves and we ended up thankful for big Jack Baker pulling off a number of good saves to keep our goal intact.
"All told, I came away relieved to still be in the cup, but I'm utterly convinced we will put up a much better display this time around just as long as the guys are prepared to roll up the sleeves and win the battle first.
"Stoneyburn did that last week and didn't let us play so I'd like to think we will meet their challenge head on and put matters straight ."
CHRIS CAIRNS is another injury non-starter for the Glasgow cracks while it's looking like work commitments will rule out versatile ace Mark Stanley.
Another tricky replay encounter is taking place across the city with Benburb hosting the visit of Fife big guns Glenrothes following a 1-1 first-game stalemate.
Bens boss Frank Lovering insisted: "We didn't play all that well last week and can count ourselves a bit fortunate to have earned a second bite at the cherry.
"Robert Tiropulous saved our bacon with a string of superb stops and it was pretty much a backs-to-the-wall performance with our only decent attacking moves coming after Scott Hendry came off the substitutes bench second half.
"Hopefully we can put Glenrothes on the back foot at Tinto Park and I'm feeling optimistic about our chances."
Bens marksman Stevie Waddell could be in line for a recall after missing his side's last two outings.
On the transfer front Ardrossan Winton Rovers have snapped up their former centre-back Darren Miller from Rob Roy whose recent acquisition of Robbie Henderson leaves them well covered in the stopper department.
