Thanks for making this video. I have a randomly smoking FR691V on a zero turn and I suspect it is the valve guide seal on the #1 cylinder exhaust valve. Wasn't quite sure if I was going to need a valve spring compressor. I didn't realize the spring tension was light enough to compress by hand. I appreciate you sharing the zip tie method as well, I wish I would have thought of that for all the times I borrowed or rented a valve spring compressor.
