Mr. Walt,
Would it be OK to contact you about an issue with my son's riding mower? It bent a pushrod on it & while checking it I saw the valve guide had slid up until there is less than 3/16" between it & the spring retainer. While looking on the net for more info there were some past post that you had made on this forum & they sounded very infomative. Your help would be greatly appreciated by me since I 'm the one who's going to have to repair it. Thanks Jimmy

Sure, my address is posted above. Remind me, model number, problem, etc.
