I just finished removing the plugs and it turned over much faster. I am draining the oil now. should I still use the Kroil down the spark plug holes?

If you can't turn the engine over with the spark plugs removed by grabbing a fan blade (with a properly tightened fan belt) it probably needs more lubrication in the cylinders. Get the rings well-lubed and spinning freely before going any further.

by grabbing the fan blade I can get it to turn over.

In that case, you should get plenty of cranking RPM with a good 6 volt starter, battery, and properly routed cables. Maybe you're expecting too much in the way of cranking speed? While the plugs are out, try a compression test. If it's got at least 70-80 PSI on all cylinders, it should start and run. 100+ compression pressure is better, but not really necessary. a 6.5:1 compression ratio engine would have 95 PSI of compression pressure at seal level if it was 100% efficient with no ring or valve leakage, something that's virtually impossible to accomplish. As long as all the cylinders are within 5-10% of each other on compression, the actual numbers aren't terribly important.

I did everything Jerry told me to do, ATF plus Kroil into the park plug holes, refilled oil with 5-30 , spun it a half dozen times with spark plug in (much much improved) , ignition off, then lug engaged the ignition, the starter seemed to much improved, after a couple tries it fired off. It is running- Jerry is a genius! I can't thank all of your for your help- till next time, I hope I don't jinx myself by writing the note- Merry Christmas stovebolters!!!!

I really think the key was the Kroil mixture, leave it for 3 days, then refill with lighter oil.

"I love it when a plan comes together!" I seem to remember spending a couple of days at a homecoming a few years ago, working with a 235 that had sat unattended for several years. With a lot of work, and a little drill sergeant language at times, it finally fired off!

Awesome. I love it when my engine starts after I work on it.. I bet you learned a thing or three as well.


Another quality post.

Those special words do indeed make us feel better - we can believe they make a difference in getting them started.
