Unhappy No Fire To Spark Plug 149 Cub Cadet

Had all the bolt on parts off engine and pulled engine to pull oil pan. Was having trouble with the tab on the cam shaft that opens exhaust valve before firing. Tab broke off. Retrieved tab from engine that had broken off and put oil pan back on. Put engine back in frame and put everything back on that I had taken off. Put oil back in and tried to start engine. Would not start. No fire to the spark plug. Checked wiring on coil and had black wire from ign. on pos. side of coil. Wire from points and condenser wire are on the neg. side of coil. Got my cheap Harbor Frt. digital meter out to start checking the coil. Set meter to 200 ohm setting and got a reading of 4.2 ohms from pos. to neg. on coil. No reading from pos. or neg. to ground. Set meter to 20k ohms to check plus to tower. Got a reading of 7.4. Do not know if this means 7.4k or just 7.4 ohms. Reset timing using static method and a test light. Took a compression test and it read 98lbs. compression. Don't know what it should read. Leaked down about 2lbs. in about 5 min. Not sure you can do a leak down test with this gauge. All this and still will not fire. Getting fuel to carb. Had fuel on spark plug when I removed it. Sorry for the long post. All help appreciated. Have a great day.
