(quoted from post at 22:44:04 04/11/12) could be you have it 180 degrees off. Make sure the marks are lined up at TDC on the compression stroke then pull the cap and see where the rotor points....
Seems to me that someone posted that some of these 172 cu. in. engines have 2 sets of timeing marks 180 degrees apart. True-false, I don't know but might be worth checking out.
ALL of you "180 out" theorist are full of it. You & I both (all) KNOW that we have NEVER seen an engine start that was timed to fire at bottom dead center (180 out)! Let the guy explore some real possibilities rather than chasing moon beams!
Jammison you can search the archives and find about 80 posts by about forty "fools" about timing being 180 out and helping someone to solve the problem. I think I'd rather be a "fool" with all these guys, who know that on one upstroke valves are open so that a spark at that time will do nothing, and the next time up the valves will be closed so that's where we want our spark. You are apparently way beyond the rest of us with your ability to get combustion with the spark occurring with out compression. I look forward to seeing this covered on the evening news.
Jammison, you may want to think this out a little more. the 801 is a four cylinder motor so when one piston is at bottom dead center there are still three others going up and down, and they are not all at the same place at the same time. Were you serious or just trying to pull some legs?
orry, Show, but you are the one that needs to do some re-thinking. Sure enough there are 4 cylinders, but they don't all fire at once, so if the timing is "off 180" as he said, then they will each spark at bottom dead center............still no start. People give all kinds of bad advice on these forums, so each reader should be full aware & think through what they read & not simply repeat it as fact..........it usually isn't.
What people accept blindly & what people don't know never ceases to amaze me! "Sometimes it is better to remain silent & be thought a fool that to open one's mouth & remove all doubt."

The man said, "My 801 barely starts, then sputter, coughs and finally dies." I said forget the 180 theories spouted by you & a few others, because he did say that it WOULD start.......note that he did NOT say that it would not start at all! Go start an engine (use one that distributor can be rotated a full turn) and just see how many degrees you can rotate it in either direction and keep it running/sputtering. It will NOT be anything remotely approaching the point where a spark is occurring at bottom dead center!!! It won't even be half way to that point. As I said, forget the 180 out business. If it failed to start at all, we could discuss it, but that wasn't his complaint. Now, you were right about one thing....you can find ''..which only re-enforces my position that you can't believe all that you read on these forums & further you certainly can't take some tid-bit and mis-apply it!
My initial statement stands!
"ALL of you "180 out" theorist are full of it. You & I both (all) KNOW that we have NEVER seen an engine start that was timed to fire at bottom dead center (180 out)! "
Your first response was to Dave 2 not the original poster. My explanation of trying to run a motor 180 out still stands!
Show:"Jammison, you may want to think this out a little more. the 801 is a four cylinder motor so when one piston is at bottom dead center there are still three others going up and down, and they are not all at the same place at the same time. Were you serious or just trying to pull some legs?"
...............and when that 'one' is firing at bottom dead center, so all the others follow and thus fire at bottom dead center. IT ISN'T GOING TO START/RUN!! You stepped in it and now just can't get it off your shoe.
I expect you are talking speculation and never even had a hands on experience it setting the timing at 180 out to observe the results, but even in your mind's eye, how on earth could you expect the piston to go anywhere when it is at bottom dead center & you put combustion or any other kind of pressure on it????? It can't go further down. It can't go left or right. It can't go up. You have nothing to stand on.
