Not much. You would be way over carb'd at low revs with a carburetor not made for single cylinder duty. If you could get it to run, it would probably start to run fairly decently about 3000 rpm.

Jetting is not the issue. Air velocity and fuel atomization are the main factors.

You actually need to OVER jet when you have too much carburetor to prevent a overly lean issue.

Big carb on small engine causes lower air velocity though the booster. That causes the booster to draw less fuel than it normally would. You need to use larger main jets to compensate for this.
