There is a puller tool that uses those holes, it's not terribly
expensive, but you could make something I suppose. I have a generic
puller that I use, but in the past I've used a piece of steel square
stock with a couple of holes drilled into it, rest that on the
crankshaft and put the bolts through it into the holes in the flywheel.
Just found out the engine does not have condenser or points according
the the illustrated parts catalog. so i guess that it is either low
voltage from the armature or bad timing. i'm going to check both of
Then it has an ignition module that replaces points condensor and can
cost 40-100$, And it has a coil, start with the plug wire- coil, it
can be Ohm checked, If you just do the replace everything deal, you
may replace everything.
First try the sparkplug gap trick. When voltage is low the spark cannot
make the large jump. Decreasing the jump can get a small spark through.
Usually, any spark that can jump the gap (when installed in the
cylinder) will run an engine, although it will not run well at low loads.
I assure you that if you pull the flywheel/magneto off you will
immediately see the condenser and the points. You cannot really check
the condenser. Check out the points for being properly adjusted
(gapped), and pitting. If this were my machine, since I'd gone through
all the work of getting the flywheel off I'd replace the condenser and
points regardless of apparent condition.
I'D ALSO REPLACE THE FLYWHEEL KEY SINCE THIS HAS CAUSED SIMILAR PROBLEMS
FOR ME IN THE PAST. If the key is partly sheared then the spark timing
can get messed up. The key can partially shear (without completely
breaking) if the blade stops very abruptly, like when hitting large
EJ in NJ
Before going on and replacing all the hard expensive stuff first do
more basic stuff, I have seen a plug that will fire out of the motor
and even in the motor but it wont take any load since a lousy plug
wire was bad. To fire gas, start, run on choke and accelerate takes
more juice than to idle. A bad wire, plug, corroded connection, can
make it not get volts when needed, under load, it just happened to my
car, one cilinder missing under load, it was a bad plug wire. An old
machine, I would wonder about the flywheel key, it sets timing, if
they hit enough rocks that might be the issue, timing off.
