Default 1973 v4 115 Johnson starting problem... Ideas

"Calif Bill" wrote in message link.net...
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.

Seems now that I do recall Evinrude, and Johnson snowmobiles. But, I
certainly know that you didn't get 80mph out of a 35hp wankel. No way
in hell. I raced BoaSki's, the last one with a 440 Rotax, dual carbs.
It NEVER saw 80mph.

For more info on older snowmobiles, including the Johnson and Evirudes, go
to http://www.vintagesnowmobiles.50megs.com/daves.html and

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.

Last I knew Rapair would sell to anyone, not just the annointed.

Maybe the problem was FatassKisser.

You are a lying sack of ****, Bill. There is absolutely NO WAY you had
a damned 35hp Wankel powered Evinrude snowmobile going 80mph. By the
way, for the record, at the time, I weighed less than 140 pounds, gear
included.

I like to do some maths. 35hp/80mph = 164 lb of force. This means if
the full 35 hp was used to go 80 mph, the drag force was 164 lb. By
comparison, a car that gets 32 miles per gallon at 80 mph is using
about 20 hp of its engine output to overcome a drag force of about 94
lb.
