wheelhorse656 20 #1 Posted April 28, 2011 well i have friend who needs a piston and rings for a h55 luason original for a 551 suburban he has been looking on ebay for a few weeks and was wondering if a tecumseh with a piston with the bore size of 2.625 over 2.626 inch would work. let me know if this is the same as h55 lauson.
