Homemade Sync Tool - Need Input

[WMarshy]

I was going to point out that you could use ATF or kerosene in them which will not matter if it gets wheezed into the engine.

Personally, I bought one of those 4 dial gauges although I have yet to try it out. Space keeps shrinking in my shop out back but the side roof project is almost done.

That one in the pic does have #2 oil (home heating oil) which is nearly the same thing as kerosene. The only problem was it was so far off balance it would going to suck it dry quickly and might have been TOO MUCH! lol I didnt want to damage anything. I did fill it with trans fluid but thought it might be too thick and drained it and put the #2 oil in it. I might go back to the trans fluid after all.

I got out my mighty vac and got them a lot closer than they were and also check the pilot screws with my color tune. With the mighty vac I found #1 and #2 cylinders pulling about 10" hg and the #3 and #4 cylinders had about 5" hg or less. I got them all roughtly at 7-8' hg and called it a day. I was thinking about giving the home made tool another try but I'm knee deep in a GM 350 rebuild for my truck.
