Hello David,
Thanks alot the Rotax is now running like a baby exept the problem of the spark-plugs A-8 dont seem to stand the stress. After 4 or 5 hours of running there is always one that wont spark anymore ??? Let me tell you that the coil is operating "A 1" and the spark that is almost ½" long when I take the plug out... Just like if the power doent get to the tip... ?
Anybody can help out ?

yah i have that problem alot also, im still not shur if a colder plug or if a little more oil in my mix or even if a little richer mixture might keep it cool enoph so it dosent crack insulator,
on mine after i get on it for a while it must idel for several minets before i can shut it off, otherwise unignighted fule air charge cracks plug insulater as motor shutsdown.
a colder plug might help. |
