that is a lot of frogs, it looks like you were having some fun for a while.
have you had time to test the O2 sensor, to see if the sensor was putting out any ohms when heated?
looking at them plugs, i am thinking of some of the things that i will be going through, it has me almost thinking of picking up a USB inspection camera w/light that plugs into a phone. just for a piece of mind, so i could look inside the combustion chamber.
last winter when i was taking apart a cylinder on the 084 motor, i couldn't get the head would not separate from the cylinder, ended up taking taking the jug and head off as one piece. i would tap it with a rubber mallet, and still a no go. ended up heating it up with an electric heat gun. and the head dropped right off the cylinder when it got to about 400 degrees. just a little more work than what i was expecting.
on a side note i could see where the fins had been bent. So the some where in its past someone had tried to remove the head and bent the fins trying to pry it off.
attached is a picture of where the fins were already bent by from the previous owner tying to remove the head. at least that is the only way i can see them fins getting bent like that.
that is just one of the little problems that i have had to deal with.
just hope you have some good luck with your findings,
Bart
the cylinders were a tight fit into the motor case, it took about 20 minutes tapping it from side to side, to get the cylinder separated from the motor casing, then it was very simple the rest of the way. just had to pick up a different style of ring compressor. when i put the cylinder back on.
