sorry if i confuse u a little guys on my description but as i say i already knew that the air pump was throwing air for sure but the i am not sure if blowing the correct amount of air to the engine also i already check the filter and try to clean it but i dont think so its the issue…like i said on my description i suspect the check valve it just i havent incounter a problem like this so i am not sure..you guys think i should replace that check valve
