ok I'm new to these and first time really working on small engines. i have a k301 engine. i ordered the tune up kit with new coil, condenser, and points. after installed it won't fire. it turns over that's it. I made sure everything is grounded and the points have proper gap . 20. i have voltage at the coil i have spark at the points. i took the plug out that has spark. I'm not sure what else to do I'm about to start putting old parts back on and see if that changes anything. it did run before hand pretty well actually besides an occasion sputter or hiccup.

I have a few basic electrical system diagrams that are helpful in understanding how the wiring system works. They are not specific to any particular tractor and do not include safety switches. All use the 5 post ignition switches 103-991 for Magneto and 103-990 for Battery Ignition. I failed to include fuses in the Starter Generator drawing, this is an over-site and I would encourage fuses be used as shown in the other two drawings.
Hope this is helpful.
Magneto Ignition system with electric start and solenoid.
Battery powered ignition system with points, condenser, solenoid and electric start.
Battery powered ignition with solenoid, points, condenser, Starter Generator and a mechanical voltage regulator.
We have uncovered a shortcoming in the factory wiring diagrams for S/G battery ignition systems with a four terminal voltage regulator. The wire from the regulator "Gen" terminal to the S/G "A" terminal was omitted. This drawing should clear that up.

Gentlemen,
I am in need of help. While doing yard work with my K301 powered ‘68 Charger 12 it suddenly came to a stop and won’t start again.
My troubleshooting so far:
Fuel:
• stabil/87 and clean
• good flow before and after pump
• carb clean, recently rebuilt, float level correctly set
Compression:
•good? - blows finger off spark plug hole
•good turnover but doesn’t fire off
•piston and cylinders move freely
•valve lash set .008 intake .018 exhaust
•breather assembly correct and recently serviced with new gaskets and filter
•head gasket not broken, head bolts tight, some carbon on head
Spark:
•no spark
•all electrical/ignition components were replaced 1 year ago except voltage regulator
•no loose connections, no grounding connections
•inspected and applied graphite to starter shaft
•changed plug
•12v to coil good
•cleaned points, points wire has continuity
•condenser ground good
•swapped battery, points and wire, plug and wire, coil, and condenser from running K301 (‘69 Charger 12)
•points push rod does push out when turning engine over by hand, but unable to get points timed using multimeter method and timing mark on flywheel
What else should I check/do?

Hi. I have a C121 which starts right up but lacks power. A compression check indicated 30lbs of pressure. I took the head off hoping maybe it’s just a gasket, but I think the cylinder needs to be honed or bored out. Based on the attached pics, is this block still good and would honing fix it?
