Title: 468 Cold misfire
Post by: Ckaz21 on July 14, 2016, 10:40:58 AM

Everything is fine at idle. But when I get on plane and when getting to plane it starts cutting out. Started doing it a month ago and has steadily gotten worse. I replaced all plugs and wires and it still does it.

Once its warmed up it goes away completely.....any ideas? I havent changed anything before this problem started.


Thanks for any suggestions

Is there a choke on this carburetor, or a chock plate flapping around? What did the plugs look like when you took them out? I'm just thinking.

The choke plate is removed. Plugs looked rich.....but its always ran a little rich
