Running bad at...

[wisconsinjimmy]

low speed. Have done the duraspark conversion complete, compression is very good 175-180 all cyl. At low speed it coughs when going thru the gears once up to 50 mph all seems OK nice and smooth. Timing 10° wires are new, checked for vac leaks and cannot find any. When I first brought it home it ran just fine. Ideas

Have you tried adjusting the mixture screws on the carb?

I have not adjusted the carb screws as it idles just fine the only thing I might be able to do is change the jets.
