I have a 2013 Troy Bilt Pony 42" lawn tractor with the Briggs and Stratton 17.5 engine. It does the thing where when i turn the key it turns a little stops at compression turns a little more stops again at compression, etc. If I take the spark plug out and turn the key it turns over normally. The battery is good and every thing I've learned by googling and watching youtube videos says to adjust the valves. I've adjusted both valves to .004 as one youtuber suggests, and to .004 intake and .006 exhaust as others say ). I've tried both settings several times and keep having the same problem when I put the spark plug back in and turn the key.
both the intake and exhaust enter and exit near the top of the valve housing so I'm not certain which valve is which. One video I watched which was for riding mowers in general and not Troybilt Pony said the exhaust valve is the one that is on top and the intake valve the bottom one - is this correct?
I do notice a sulfur / rotten egg smell when I try to start it - does this help diagnose anything ?
I'm at a loss - any suggestions on what I might be doing wrong or whether it might be a problem other than the valves like the solenoid or something would be greatly appreciated. :confused2:
I work on my own cars when they need repaired (have done head gaskets, brakes, etc.) but this is the first time I've tried to adjust valves.
