Hi Guys
I've have a briggs 8hp on a rover colt that I bought a few weeks ago.
I've replaced the coil, carby and given it a freshen up but I can't get it to run smoothly. It almost runs as though it starves for fuel intermittently. I've had the same issue with both the new and old carby. I've gotten it to slightly improve with giving it a tune but it does continue. Some of the head bolts weren't all that tight which I only noticed the other day but I'm not sure if that would have any bearing on it.
It does seem like after 5 or 10 minutes of mowing it seems to gradually get smoother. The governed appears to hold steady it just sounds almost like I'm sticking my hand over the air intake about every 5 or 10 seconds.
Cheers
