Timing backfires out carb. Carb backfires out exhaust pipe. Could be you have it 180 degrees off in distributor. Make sure you have it on compression stroke.

You're maybe 180 degrees off. Use a timing light to check; make sure that the timing mark is in the right place.

You could take the belt back off and take the first spark plug out, put a slim screwdriver on top of the piston, take a wrench, turn the crank shaft till you feel the piston top off, then it will be high sided, put the belt back on and replace the spark plug; it should fire up. You might have to tinker with the distributor to smooth out the idling.
