John Deere H

[treeman53]

How warm does A JD H have to be before it will run smooth without half choke? Just got the H running, and if I open choke, it starts missing and wants to stall. Temp gauge was still not climbing, had it running for about 5 minutes. My other H starts with half choke, and can open choke almost immediately after starting. Outside temp is 70 degrees.....

Sounds like carb may need looked at.

All the brass plugs need to removed and the proper drill bits used to clean the passages.
