Fuel Tank Problem

[SavagePower]

I think the issue with my idle has to do with the fuel tank. No matter how I tune it. Just give it a tiny throttle, and then press brake. The idle stays up for about 4 seconds and then starts coming down.

It's either I have a leak from the engine to the exhaust or something.

When you give that little throttle, it has enough pressure to push the fuel in. Once you let go, it does not have enough pressure to push the fuel in therefore idle stays up high a bit until the pressure builds up again and then the idle comes back normal.

I have been having issues with priming my engine, never had that with my old engine. What do you think?

Another issue is when I lift the front end up, idle comes down to normal(Wheels not moving). When I lift the back end up, idle goes up very high.

another issue is I rich up the LSN a lot already, do a pinch test, it dies immediately. When I run the truck, way too much smoke, and fuels splitting out of the engine. So I'm guess it has to do with fuel pressure.

this sounds like lsn is lean (pinch test) hsn is fat (spitting) what is your idle gap set to ?
