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.

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?

So gang, it's Christmas time and my company has extended its forced vacation to two weeks, sucking 7 days of FTO from me. I've got all kinds of things to do for the wifey-poo but what the heck can I do for me?
I've got two K301s so may as well get out the surgical tools and do a b-gearectomy. The C-125 goes first. Restored that back in '17 and so she's got maybe 75 hours on her. It'll be rather painless and the youngster is visiting so can assist in getting that b-itch up onto the bench. She's already been moved to the garage and the old Kawi and its carb parts moved back to the shed while I search for tiny o-rings. Wish me luck and pics to come. Oh, there is no rattle BUT she's always had a minor knock I chalk-up to excessive end play (didn't measure it back then 'cause I'm bad but, dang!, will now).
