So I finally got a chance to start my 420A-T for the first time I completely rebuilt everything about the engine it's self haven't touched anything else about the engine bay I got it to run by jumping the starter it won't start with the key that's the first problem I ran into but the main problem it don't wanna stay running and when it does stay running it idles at 2k rpms I have no oil drips or burning oil but after bout 5 mins it drops idle and dies what would be the cause of this I got new spark plugs also but everything else hasn't been touched .
 
I've been out of the DSM scene for a while so not going to answer what it could be cause I have no idea. But just because you didn't touch something doesn't mean that it didn't get messed with from all the other things you did do. Just double check everything you could've bumped a wire or a plug somewhere.
 
Makes perfect sense but everything seems sound.. it won't even start now you think maybe it sitting for 5 months could have gotten bad gas now ? And that could be a issue ? is was having this same problem before the re build but it's worse now
