I have a 1993 Mach I 670 Rotax - not sure if my problem is fuel or electrical? Acts like its starved for fuel or ignition system is not getting spark all the time. Anybody have any suggestions … we have 10 inches of snow and I'm in the house on-line!! Help!!
Make sure that you have the correct spark plug and that it is in good/new condition. If you have non-resistor plugs and it calls for resistor, it can foul up the Ign. pick up coil/module and lose spark. What does the piston wash look like? How about the spark plugs?
