Remove the plugs. Turn the engine so the pistion is at top dead center for cylinder. Clearance should 0.010 when adjusting rocker to valve. Repeat for other side. I just replaced my cam shaft if a 1993 JD445. I'm planning to run for a couple of hours then check cleanace again. Hope this helps, Gerry

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.

Hi

Please check for the anti back fire solenoid in the front of the carb. Check whether the wiring to it is fine and if it is getting +12 V. If yes then you maybe required to replace the solenod.
However, if this doesn't resolve the issue then you would need to adjust manually so that decompresser works normally. Inspect the flywheel key as well, it may have sheared.

Check the carb filter and the make sure there is no sign of water in/around the carbeurater. Hope this helps... If it does please do not forget to accept the solution or post back for assistance.

The cam has broken, this is a common problem with the 425/445. The cams are very cheap, made with plastic. Had mine replaced last year at the cost of about $300. Had water pump replaced as well.

Bent pushrod on inlet valve,husqvarna rideon mower


it is one of two problems - your engine uses a cam with a plastic gear - this gear has a tendency to move - it will probably need replacement . there is also a chance that the valve seat is coming loose (overhead valve ) which keeps the valve open - check the distance of the valve stems to make sure they are both out the same distance if they are not then when you put a new pushrod in and adjust it the valve will be pushed too far and hit the piston in turn bending the pushrod
