If you have a Brute Air Compressor like mine is a 10GAL, 125psi. The issue were it never filled up to beyond 80psi, I noticed the cold start valve kept on spitting out the air the compressor generating thus not filling up the tank. I did some research online both google and youtube and none of them really help. Some tell me to change the check valve, some told me clean the compressor, change the oil, check for air leak and so on.
After careful review I noticed the cold start valve is the culprit. I can’t really tell until I removed the cover of the compressor, which is dangerous if running without the cover but it helped me trouble and pinpoint the problem. I was indeed the cold start valve.
I do not think you need the exact same model made, as long as it fit is good enough, since these cold start valve basically will not pump the air into the air tank if it’s less than 20psi. So as long as it then it’s good. I got mine from ebay for $5 and it work perfectly no issue now, just like new now.
