Hi just wondering if anybody can help?

My son was recently given a dt125r, i think its a mid 1990's model, to use as a field bike.

When we got it the carb was missing and the wiring was a mess!!.

I managed to rewire it and i and i bought a secondhand carb, which fitted fine, but when we try to kick start it, all it does is back fire?.

The carb has been stripped and cleaned.

It has a good spark, fresh petrol, new plug, its getting petrol to the carb and to the engine and it has good compression.

Am i overlooking something simple?. As its a been 20 years since i last messed with a 2 stroke.

Also its the model with electronic ignition.

Why it wont start??

checked the reeds?

usually chipped/snapped reeds cause loss of primary comrpession and backfireing.
