Thread: New 496 wont run??

Tweet

Okay guys, I didn’t want to cause a fight, I just wanted some help. So back to what I have done, last night after the car sat all day I went and turned the mixture screws in all the way and backed them out only half a turn, opened the idle screw up a bit and tried to start it and it started instantly and ran at about 2200rpms. I let it run for about 4-5 mins and shut it off. Checked for leaks and then started it again, it was idling way too high so I closed the throttle screw a bit and it ended up dying again.

After that I pulled number one plug and Bork scopes the cylinder and found just a tiny bit of fluid built up on the piston. I opened the throttle a little bit and it ran again but at a higher rpm, I can’t get it to idle very well at regular idle but I didn’t have much time to let it run and warm up though.
