I'm new to the forum - first post. I have the engine out and intend to replace the timing belt, coils and water pump - all are on order. Short story - the tractor, after not being used for a couple weeks simply cranked but would not start. No Spark, so I assumed coils. Proved by testing resistance after pulling the engine to get to them. While the motor is out I'm considering also replacing the 21 year old starter motor. Can this be removed without having to remove the crankshaft and camshaft pulleys and the inner engine cover? AND has anyone been able to buy the original Denso motor without having the $300++ that Honda wants. I think the Denso part number is 9702889-028.
