K341 Timing

Recommended Posts

Anyone familiar with K341 timing, could you give me instructions on setting my points? Where are the timing marks on the flywheel or even how many thousands of an inch before top dead center? I know the gap is .020, but I don’t know where the timing marks are. Thanks Charles

HI, If you look through the hole on the side of the blower housing, you can see the ring gear on the flywheel. On the block side of the ring gear on the flywheel are 2 marks. I usually use a wood stick or one with a piece of rag wrapped aroune it and clean the flywheel off by turning it when the stick is against it. There will be a line with the letter S. 20degrees later or about an inch and a 1/4 will be another line and the letter T. There is a little point on the side of the timing hole on the aluminum closure plate. I try to take some thinner and clean the marks out, and then sharpen a popsicle stick or similar and put some yellow paint in the marks. Any time we have an engine out and the blower housing off we wire brush the marks off and paint them. When we put the engine back together we put marks on the screen and the blower housing on the outside so they are very visible marking them correspondingly S and T. (Note: The S mark is for spark, 20 degrees advanced and T is for Top Dead Center, not used for igniton.) I usually connect a test light to the point wire at the coil and the battery plus terminal. With the key off I rotate the engine flywheel clockwise until the light goes out. This should happen when the S mark is in line with the pointer in the timing hole. If it doesn't adjust the points so it does. One thing, do not go past the mark and check it coming backwards, because of the gear slack in the camshaft. Turn the engine backwards a few degrees before the mark and always check it going forward. This takes the gear slack out and this how it will be when it is running. We never check the gap, we just time them this way. Then we start them and check it with a regular timing light through the hole or by our added marks. Should be right on. Al Eden
