Sportwin 10

[58rude]

Had her up and running for about 20 min. I played with carb adjustments and got it running at a good, slow idle, just not that nice, low, antique, magneto, pop pop pop idle, that I have seen videos of these engines doing. When I can get it to idle pretty low, she will run for about three minutes, give one lean sneeze and die. Move throttle back up a little and she fires first pull, but chokes a couple times till fuel gets back, then will run fine. I fattened up the low speed a little but, it starts running pretty rough when idled back down low. I'm stumped.

Have you rebuilt the carbs?

 

[58rude]

The carb was torn down and soaked in chem dip, blown out and assembled with new kit. I pulled Welch plug also when I did it.

do you have compression no.'s ?

 

[58rude]

No I haven't check it yet. I got a good thump thump when pulling through, so I knew it had enough to run. I can test it though, I know it's important. Will one low cylinder make it do this? I don't disagree with you, just don't understand the theory behind it. I respect all of your guys' expertise on these motors, great place to learn a lot.
