Greetings to all. This is my first post here, I've come accross a little snag that I'm hoping some of you have come accross before . I've just removed and cleaned the carb ( LC4 640E 03 ). In order to get space to remove said lung I'd unbolted the sub-frame and eased it away from the frame, now having replaced the carb I've found that the sub-frame will not fit back over the two lugs on the frame. Sub seems to be about 4mm too narrow. Has anyone else found this? Is this the time to use a brute forcing tool ? Any pionters would be greatly appreciated. Cheers. Les.
