Wankle powered. 35 hp about 80 mph in our version. They also changed
the
carb system for 45 HP for the racing units. Was a great machine. Rode
2
adults comfortably and had a reverse gear. Somewhere we have pic's. My
kids loved driving that thing. But when you are 8-12 years old, is fun
to
drive anything, including the dune buggy.

About the hard starting V4 115hp, that motor needs at least 350 rpm at
cranking to generate enough juice to charge up the ignition system capacitor
and to trigger the sensor coils, telling the pack when to "fire". The sensor
coil to flywheel spacing is critical and there used to be a factory tool
that set that adjustment. It is also available from Rapair/CDI Electronics
that can be ordered by a marine professional. Most hard starting on those
motors is due to slow cranking rpm from worn starters, bad cables, or too
small capacity batteries. This is assuming that the motor is is good shape
internally, and that the fuel and choke systems are operational.
