I am not looking at an engine right now but the positions you mention here DO NOT sound right. I believe the TDC mark falls about the 1 o'clock position and 25* ATDC would push the mark on the dampener to about the 2 o'clock position at most!!!! Like I said, I am not looking at an engine right now but 3 o'clock and higher seem way off.thbjcb said:I tried the finger test and it was pretty easy to find the compresssion stroke. I then set cam sensor with the caspers cam setting tool. The postion is now exactlly where it was the very first time the engine was running for 10 minutes. So some how I had off for the last couple of days.(second guessing my first setup) So i tried to start it and it kept firing but would not start. Going through the directions with cam setting tool it said at zero TDC the notch in the metal cirlce should be around 3 o clock and at 25deg it should be around 5 o clock . My first one was at around almost five and the 25 deg was at 6 ?????
I tried the cam sensor in two other positons slightly clockwise and counter clock form the correct postion and it definallty did fire very much at all
Things i am going to try next
1. Draining out all the old gas and trying new gas and filter
2. Any other quick ways to test out the bad fuel theory?
ANY OTHER IDEAS??????????????
About the fuel. I have left fuel in partially filled tanks for 2+ years - out doors with very high humidity and wide temperature swings teen in winter to 100* in summer. I have never had a bad gas problem, but I know people that have had issues with much less stagnant time. The fuel gets a musky odor to it - kinda like a cellar in an old house that has some earth floor space. Bad fuel could be an issue and pumping it out is easy to do.
I would use the method mentioned above on the old filter and a strong dose of dry gas/alcohol to help suck up any water that might be in there, then run another gallon of fresh fuel thru it, observe the flow rate by timing the volume in seconds per gallon and observe to condition/color/odor of the fuel, then install the new filter and try it out with fresh fuel.
Are you sure the cam sensor is all the way down and not busted internally? Some have reported trouble with the steel ring under the cap - on top of the sensor.
