Question about John Deere Garden
It sounds like the camshaft timing is off. Did you have some marks to match up when you put in the new camshaft?
Posted on Jul 09, 2014
Of the 100+ camshaft replacements that I personly have done on the 425/445 and John Deere Gators I have come across 3 that backfired when completing the replacement.2 were do to bent valves coming in contact with the piston after gear failed and 1 was from a sheared flywheel key.The only other time I had this same injected engine backfire was on a John Deere gator 620i that had a faulty computer and fired @ 90 derees off.Do a compresion check and that will help out alot.
