It has been a while...
So learning I did an 'incorrect' compression test list time by not removing all of the spark plugs and not performing the test with a warm engine.
Couldn't do the warm test as a rusty fuel system made fueling impossible.
So I purchased a $100 chinesium carb off of
amazon and plumbed it up to a jerry can and the ol' 2F ran for the first time since ~2008.
Now that I'm able to run the motor(cant actually drive, tires are shot. just have to let idle or hold RPM for ~30min to get it warm) and get it warm, I didnt another compression test a warm engine. Pulled all the plugs and these were the results...
Hot Dry
1: 157
2: 148
3: 151
4: 157
5: 165
6: 157
Not bad I reckon.
Then I quickly repeated the test with a small squirt of 20w50 in each cylinder. Not sure how much it should have been. Used a syringe -- maybe 1cc each?
Hot Wet
1: 167
2: 155
3: 160
4: 165
5: 168
6: 160
A slight increase.
In addition to getting the 2F to run up to temp, I decided to do a valve adjustment.
The FSM I have says to do the adjustment warm with the engine running. I had never done that before.
First time for everything. Definitely a core workout, having to lean over and put tools to adjust those mini jackhammers.
After a running adjustment I immediately did another compression test.
1: 179
2: 175
3: 155
4: 164
5: 179
6: 184
I did a brief google on 2F compression results and I dont think I have found any this high. Did I do something wrong or is this just really good news?
Disappointed in 3 and 4. Perhaps another clearance check is in order since it my first time doing so on a running motor and it was a bit bumpy.
What are y'alls thoughts?
