No spark

[crosbyman]

why not just start with a good wash down with a strong spray of  automotive  disc cleaner …or carb cleaner followed with a strong  air compressor blow job.

 

Wipe the points clean & set  the points at .020 (the usual spread) on the high spot of the cam lobe.   at the very least perfect or not do test  the condensers with a analog VOM  for a kick on the needle, opens  or shorts.  Some  digital meters will test uf value but it is not a 100% guaranty.  Condensers need to be test at high voltages for leaks   !! see diag for a very basic test cct.

 

better  yet build yourself a Mohat test  box  which will boost the  commercial AC peaks  up to about  270+  dc volts  !

So I pulled the mag off went through it again set the points .020. Did I mess up the timing by pulling the mag off to clean under it? I couldn’t get it to fire up. Back in the shop this morning trying to get her going.

Okay then, from the video I see I didn’t mess up the timing. Am I getting this right? Should there be some lubricant on the mounting surface of the motor and mag? Moving to the next thing  the compression is just under 90lbsqin is that enough?

Do you have a VOM?  They are very useful when evaluating ignition components.  Put just a small amount of grease where the mag plate rotates on the block.

When testing Compression it is more important (or meaningful) to have equal (within 10% or so) numbers on both cylinders.  Gauges vary as well.  I wouldn’t worry about the compression at this time.  You will likely see the numbers go up a bit after the engine is run  for a while.

So;  you have good spark on both plugs now?

Negative on the vom. Trying to get one from a buddy. I feel like the dog chasing the car what do I do with it when I get it?

Yeah seems to have good bright light in the tester on  both cylinders.

The compression was pretty equal in each one too, so yeah not to worry now.

try utubes on use of VOM… basic electricity tutorials  are plenty

One thing to look at is fuel flow from the tank. The tank has a fuel filter inside the tanl.Please remove the big chrome nut under the tank. That will expose the filter, stud, nut & holding washers. See if everythingis in place, Ive seen them in all conditions. If there is no filter go to a chain saw shop & buy a in line fuel filter there. Remember that small of a carb has tiny fuel passages & require a good filter.

While at the lake my KG7 was acting up.  I removed & installed the low speed jet & a tiny piece of something came out. It ran so much better just with that flush. And as Tubs said check all wires for clearances too.

Compression in this motor is 90 & 95 lbs. Video link – https://youtu.be/sm4M0xnXm-I?si=HmU6WPXw6-c84noa
