It sounded real sick to me. Don't forget to leave a section hanging out to remove it when you are done.

Well the cord worked fine. I ended up using about 3 feet of 550 paranoid. It did take two people to put the valve retaining clips back on. It still is not starting, so I ordered a new carb. Any other ideas would be appreciated. I also got some no ethanol unleaded gas.

Paracord, perhaps? :laughing:

Glad it worked for you on the valves. Bummer that it won't start yet. :(

Today I put on the new carburetor. I got it started but for the first start I had to disable the spark on one cylinder and then once it started I reconnected that spark plug wire. I have now started it about 10 times and while it did backfire a little through the carb, it started. I now am guessing that one of the coils is doing something strange and have ordered a new coil. The engine runs kinda of rough at idle. My guess is that the automatic spark advance on the bad coil is stuck on advance. At least I can use it again. I borrowed my neighbors mower with a Kohler engine and it started great. I talked to Terry at Power Trac today and they have PT with Kohler engines. They still have some left with Robin engines.

So the future for now is new Kohlers from PT?
That would be good news. Very few people in this forum seem satisfied with the Robin engines.

I think the Kohler is a really good choice for PT. It removes the weakest link in their smaller tractors. Terry says that they start much better.

I ran a test today and disabled one spark plug at a time. It ran worse on the side I suspect is a problem.

Bob, you should have done that earlier.

I didn't have the coin to drop a Kohler in last year or would have done so instead of a valve job on the Robin.
