Buy yourself a spark plug wrench for $15. Change the top quality Iridum spark plug for $10. Change normal quality air filter $5 - $10. Change top quality fully syntetic engine oil $35.
My experience is go to Chinese mechanic, not western mechanic. You can find 2 Chinese mechanic at Gladstone, between Parkdale and Bank, Summerset Ave behind 168 grocerry store, Scott at Carling
I don't want to give the shop name directly, just in case people think I'm doing advertisement. No offense
