compression

[superj]

i was bored and did a check on the ol compression on the jeep.

i ran it twice and the engine was driven within an hour of this being done.

here are the plugs. number 6 is on the top

they were gapped in a wide range of setting. i cleaned them and set them all to .038 because i didn;t have the listing of what they should be and they were so badly set previously.

roughly a 3 second crank

6: 162
5: 150
4: 160
3: 165
2: 165
1: 160

roughly a 7 second crank

6: 185
5: 185
4: 185
3: 185
2: 180
1: 180

then, me and my youngest son went and tested it out

small pile side:

large side of the pile:

dang bumper caught us up

Been wanting to do a compression test on mine, this makes me want to get on it.

I was kind of surprised since the book said it should be from 120-150
