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.

Thanks and yes I have watched that and other videos but most are on the same line as that one where it tells you what the adjustments are but not what they do and the effects on the carb and engine running performance when you do change them. I haven’t really found a video that really covers this well so I can really understand what I am changing inside that carb when I do those adjustments.
