still having heavy valve tick sound unless engine is 100% working warm. I checked with stethoscope for fan hitting shroud, exhaust leak, timing gear noise, etc. Still sounds like valve tick. I pulled spark plug wires off individually, and engine still makes the same amount of valve tick noise even while running on 3 cylinders. So I'm thinking that eliminates piston slap, wrist pin, etc. I did notice that upon mild "throttle up" of engine RPM, ticking stops, upon pushing throttle closed and at idle up to about 1100 RPM still ticks, but seems to go away upon pushing "throttle up" for more RPM. Anything over 1200 RPM or so, no noise. I added lead additive to the fuel. Any ideas would be appreciated. I should have dropped a feeler gauge at tappet clearances, with the engine running, to see if I could nail down when valve it was, but I forgot to do that and put it all back together...pained etc.

The garden was already sprouting when we hooked up the mid-mount shovel cultivators to the Pony. The seed bed was soft enough that the rear end would spin and slowly work its way to the downhill side of the gardens slight incline. From this, we learned our lesson sinc
