Mounts to engine with 4 bolts 5 7/8 apart on center. 2 3/8 center to center carb mounting holes. The exhaust valve will move but is tight – spring looks good. The intake valve is loose and will need a new spring. The fuel saver spring could stand to be replaced. No breaks, cracks or welds that I see – some pitting along the bottom of the head due to age and use and a casting flaw by the carb mounting. Please feel free to call me with questions. My parts inventory has grown out of control, so set a reminder to check back frequently for new listings! If you don’t see a part you need listed, good chance I just haven’t gotten around to it yet, so just check with me. Like I said, I have been doing this a long time and try to list everything accurately and to provide a detailed explanation of the item, both good and the bad. Check out my other items.
