Hello Sir!
Lately, I have been looking for someone that does any sort of blasting to clean intake valves due to carbon build-up. Sadly, I did not find ANYONE in Montreal nor Toronto willing to perform this service. Then I landed on your thread from 2016, if I remember well, saying you are able to. I would really appreciate if you could let me know if you are still willing to perform such service, because you really are my last bit of hope...
Hope to hear from you soon,
Cheers,
Vlad
