View Full Version : Kawasaki on exmark won't start
04-30-2008, 02:02 PM
I Have a Exmark metro 36, with a fb460c Kawasaki. New carb, NGK plug with good spark, I get some back fire through the carb, I've had it running and runs great, just hard to pull start, many pulls! I'm trying to find a service manual, and I'm thinking about grinding the valves and seats. Any input is welcome.

Backfiring through the carb is a good sign of a non-seating intake valve, A leak-down test would verify this.
Here is the valve service procedures;
Also check the valve guides for wear should you open it up.

Thanks for the info, I just ordered a service manual and I hope to pull it apart this weekend. My dealer is 7 weeks behind, I'm hoping the local machine shop can grind the valves and the seats, I can lap them but that's about it.
I'll post an update later.

I pulled the head and found a few of the bolts loose. I will check the head for warpage, The intake valve has a groove worn in it. I'm going to take the valveS and see if they can be refaced. I'm hoping to find a place that can grind the seats in a day or 2 vs the 7 weeks the dealer is behind. I think the auto motive machine shop in town will do it.
I received my service manual today.
I'll keep you posted.

Got the valves refaced and lapped in, they look good, I set the valve clearences. Now I need the gaskets and see how it starts.

Got it put together, and it started on the second pull runs great. Thanks for all the help.
