Long cranks and setting points, 124 k301

Rwgarrison23 · #1 10-19-2019, 06:13 PM

She's alive! I do have some concerns. K301. I tore it down to clean it up, put new headgasket on, reseal everything. I didnt take the engine completely apart. Just freshen up, with new points and such. So, she starts up but after long cranks, after maybe 8 cranks and she fires up slowly. I want to make sure I set my points right on the timing mark. Do i set it on the S or T mark at .020?

Once it is running, How does it run ? How is it at high rpm?

Set using S.

If using a timing light you dont set gap with feeler. You adjust until S is in center

It runs pretty well i would think. I'm not sure whata normal for these Cubs. This is my 1st one ever. At high rpm, it sounds like its misses a little bit.

Ok.. did you set the timing with a light to the S mark?

Also, did you use a new condenser?

While I am doing timing I usually check the high rpm also to make sure im at 3700 with no load. Some guys say 3600 But I like mine a bit higher

No, I set it with a feelers gauge, I cant remember which mark I set it at to. Everything is new. I do have a timing light I can use.

When the "S" mark is in the window the points should just be opening. Use an ohm meter or test light to find the point where they break (open). Setting .020 at the "S" mark has them opening way to soon.

He has a timing light. Just run it. Adjust points until S mark is in center

School me on that, this is something I never done. I done plenty of air cooled vw but cun cadet, I'm not sure if its same. So as it running, does it need to be at idle or wot, and at what part of the point do I move it so I dont mess the plunger up?

Loosen the screw just enough so when you use a screwdriver in the notch at the top of the points bracket you can move the points in and out but they will stay there until you tighten the screw. There is no timing advance so speed doesn't matter, just run it at a speed that is smooth so it's easier to adjust without the engine bouncing around. If you set the points at .020 at their most open position you will be pretty close to start with.

Sounds simple enough. Is 020 stock spec?
