Welcome to Iboats, Racex!<br />I can't remember if that engine has a kill switch or not. If there's any wires coming down from up underneath the flywheel (other than the spark plug wires), disconnect them and check for spark again.<br /><br />If you're still not getting any spark, there's something wrong up underneath the flywheel. Post back for suggestions on how to remove it.<br /><br />Good luck!

The nut that holds the flywheel,is it clockwise or anti-clockwise to loosen it up.And the threads on top the flywheel to hold the puller what treads is it.In Sweden we only have the millimeter system.Please adwise.

Counter-clockwise to loosen the flywheel nut.<br /><br />The three holes for the puller are 1/4" UNC threads--20 threads per inch. A good hardware store should have those available for you, even though the metric system is used in Sweden.

It is anti-clockwise, like a normal nut. It's torqued down pretty hard (55-60 Nm). The threads that for the puller a 1/4 (one quarter, or 0.25) inch x 20 threads per inch. This is a very common bolt in the US & Canada, but it's going to be very difficult to find one in Sweden I think. One possible solution is to drill and tap the flywheel for a M8-1.25 fastener. This is very similair to a solution we use here if the flywheel's threads strip.<br />Use at minimum a grade 8.8 bolt.
