4x4forks 258 #1 Posted May 19, 2019 Hayter ride on started smoking and burning oil so did a bit of resurrect as it starts and runs great. After a watch of good old You tube, a simple examination of the spark plug diagnosed a blown head gasket which apparently these engine are prone for. Stripped it out this morning and there it was ,blown from the cylinder to the oil return to sump gallery. Kits to be order Monday morning 1 nigel reacted to this Share this post Link to post Share on other sites

Wristpin 400 #3 Posted May 19, 2019 I’d certainly check the heads for flatness but also re- torque them cold after a few hours of running. 1 4x4forks reacted to this Share this post Link to post Share on other sites
