stevebo-(Moderator) 8,058 #4 Posted November 29, 2010 Here are both engines for the 550 and 551. 551 has the straight carb and the updraft one is for the 550. Share this post Link to post Share on other sites

SkyhawkTL 19 #6 Posted November 29, 2010 Tecumseh H55D 2113 was original on mine - And through Redsquare I found the H60 shares many parts - Gaskets etc. The original alternator was pretty basic - no regulator - but it worked. Good luck. Share this post Link to post Share on other sites
