Also the cheap way to check your valves is to put a dollar bill up to the exhaust, if it blows it out the valves (exhaust) are OK, if it sucks it in that is where the problems begin.

I guess the pushrods on the forward cylinder had loosened and had the valves stuck open.

Do a compression test. It's really easy and the gauge is not expensive.
I'll go with 'not opening' or 'partially opening', but NOT stuck open. When they loosen, it is the same as if they are too short. TOO TIGHT will hold the valve open (off the seat).

IF the rear is 'cold', it ain't firing. AFTER you run the comp. test, get one of these. They are 'cheap', and really all a backyarder needs to check the spark. Qwik and to the point. If it will 'spark' with this, you have spark.


If you have the 'guts', while it is running on only one cylinder, hold a lighter to the rear exhaust. IF you are getting fuel (which I still believe you aren't), you'll KNOW it real fast. It will act like a flame thrower. The non-burnt AF mixture will ignite with the lighter.
