I went out and tinkered with the TroyBilt today. With out the spark plug it turns over just fine. Put the plug in it and it barely will turn over by hand.

 

 

Any Ideas?

I think that happens when the valves need adjusted. I have no experience with this problem but I've heard of other people have similar problems.

Is there a compression release on this model if so might not be working.

By the way I like the fuzz on your head :D I can't grow any hair on my head so your one up on me in that department.

It's especially true on the OHV engines. It opens the intake slightly for comp release.

Check the valves like Doug and Farmerall suggested.  Make sure they are opening and closing.

Battery good, starter good, bad engine ground ? I had a starter for my snow blower once that turn over great on the bench put would not turn the engine fast enough to start engine. Just wondering, Noel

I hooked it directly to the battery in the Hemorrhoid with jumper cables.

 

I will pull the valve cover off tomorrow and check it.

My neighbor had nearly the same problem with his troybuilt. He had to have a new cam and push rods put in which the parts and some labor was covered by Briggs. He had problems for a year or so. He would adjust the valves and it would run well for a while and have to have it done again. He and I did this several times. He took it to a dealer and they charged him $350 to fix it. had it for over 6months. Got it back and it did it again. This time when he took it back he called Briggs and complained. This is when they put a new cam in along with the new push rods. After this it ran well but he had no confidence in it. He gave it to his longtime friend has bought him a new Comercial Husqvarna Zero Turn with a Kohler motor in it. He did get $100 back from briggs.       When it was acting up it wouldn't turn over if there was a spark plug in it.                                                                                                            Roger.

Reset the valves. It'll turn over and fire right up. 

Check on you-tube for a video .  you'll be surprised at  the difference.  I recently experienced this with the same engine.  The valve clearance loosens up and there isn't any compression release.  Rick

 

There is a good explanation on youtube.   search for (how to adjust valves) Fix hard to start lawn tractor with ohv

by donyboy73 .    It's a two part video and he explains the how and why pretty well.

I read on your other thread that you got it running.   :thumbs:    Amazing what a difference that a few thoundsandths of an inch will make.
