What makes you think it is that?. 

Start simple, take your spark plug out and spin it over whilst holding it against the engine casing to see if it sparks correctly. 

If it's spinning over faster than normal that would indicate to me low compression... Ideally get a compression tester from a mate or local garage/ebay and test it properly. 

Check your float bowl is clean, there is a good flow of petrol coming out of the tap, any in line filters are clear.
