Hi I'm new to this forum, so go easy on me. I got a GK76A last month and it was a non runner, wanted it as a project. I got it started up but it will not idle and its got really slow pickup up till about 6000rpm, but above that its nice. What do you recommend that I do to it to get it running smoothly? I've been told that the o-rings will need replacing and that I will need to clean the pilot jets out. If anyone else has had a similar problem and sorted it I would appreciate any info. Thanks
