Piaggio sfera (zip) wont start

[padly1995]

Hy i bought piaggio sfera (same frame and engine as Zip) that was sitting in the basement for 5 years, i drive it for about 0,5km than i cleaned carb with air compressor and checked if oil pump is working -its working! I Put new fuel and oil in it!
I took it on a test ride and it was running well, but the engine was kind off hot i think!
Engine looked wery bad so i took it off and cleaned it with wire brush, than i putted it back together and rev it on the stand, turned it off and rev it again and turn it off normaly! Next day i wanted to start it, it started and died in about 3 seconds... now it wont start :S

I got spark, fuel and compression (piston is new, cylinder is not that bad)!

I have 19mm carb 72 jet and malossi MHR air filter on it!

I know that carb and jet are too big but can this be the problem if scooter was working with same setup all the time before? Thanks
