I had to remove my rotary valve cover to tap stripped out carb bolt. The actual valve itself had grooves in it and a small knick on the edge (looks like it had swallowed a bolt at some time - I can see a matching knick on the pto opening on the engine block). So I replaced with a new valve, used the timing wheel, and pretty sure I got it timed correctly. When I checked the valve clearance with feeler gauge, it came up that it had too much clearance, and I can tell that the rotary valve cover has been machined before. I put it back together anyway, figured if it was running ok before then would be ok???
Now when I start it, appears to be running rich, lots more smoke than usual. Also hard to start back up when it has been running for several minutes and I turn it off. This has all been while connected to the hose in the driveway. On the lake, couldn't get it to start when warm.
I'm thinking the problem is the excessive rotary valve clearance and that I need to order a new RV cover. Thoughts??? Or is it possible I might have the valve timing off very slightly and that would cause this condition?
Also - if I do end up replacing the RV cover, was thinking about getting it from SBT - it's $150 cheaper than dealer. Anyone have thoughts on that?
Thanks!
