Re: LA115 Weird Starter Issue
Bad news. I adjusted the valves, but still have the problem. The exhaust valve was out a bit at .008" but the intake was in spec at .003". As soon as I saw that the intake was adjusted OK, I had a sinking feeling the problem was going to be a broken compression release (CR).
Can the CR be replaced or do I need a whole new camshaft assembly? Governor still works, so didn't get damaged. I saw a reference to just adding an extra head gasket to reduce compression so not to need the CR. Of course there will be some drop in HP. If this works and I could do it without removing the engine from the tractor, it would be a fairly quick fix. I really don't have the time to remove it and tear it apart completely as I have more pressing issues to address in the next few weeks.
Right now, I just have to raise the hood and spin the engine backwards a couple of revolutions and that gives the starter enough of a running start to get over the compression hump. Also, revving the engine and shutting it off at high speed seems to stop the engine well off the compression stroke frequently. Wifey will just have to learn to run it backward before starting or get used to driving the LGT 145 for a while.
Could there be any other cause? Like high carbon buildup? I noticed the plug was pretty carboned up when I removed it to adjust the valves.
Thanks in advance for any input. I'm all ears, or rather all eyes to be exact.
