Mountfield SP474 with RM45 engine running lumpy (rich).
Discussion
Hi everyone, new to this forum and would just like to say hello!
I have a Mountfield SP474 with a GGP RM45 engine fitted to it. It runs really rich and lumpy. I have ultrasonically cleaned the carb twice, I have Fitted a new carburetter gasket kit, changed the coil and spark plug but to no avail.
I am now thinking that I have somehow got the gaskets mixed up causing my problem. I have searched on the Internet for a diagram showing the correct order and positioning of these gaskets but again to no avail.
Can some really kind person please advise me of the correct fitment of the gaskets or alternatively a possible solution to my problem.
Thanks in anticipation.
I remain yours very frustratedly

Hi again,
Firstly thank you for all the replies. It appears that all you people think it is a carb problem.
Right, I have removed the carb and yet again ultrasonically cleaned it. I then cleaned it again with carb cleaner. I subsequently refitted it and it ran perfectly for about 30 seconds, and then stopped ( it appeared like fuel starvation) albeit the fuel tank didn't appear empty I topped it up. It now starts up on choke and runs for about 5 seconds and then cuts out. It will restart immediately and again cut out after the five seconds. I am very confused.
I am now thinking of fitting an inline filter?? Any advice please?
Thanks in anticipation
