I recently bought an old 5 hp Troy-Bilt Super Tomahawk Chipper Shredder. The thing starts right up but as I try to engage the chipper with the lever, the engine stalls. The guy I got it from had no problem engaging during my demo, but I can't seem to get the hang of it.

Would loosing the tension on the idler wheel help?

Should I put some silicon on the outside belt that touches the idler wheel?

Perhaps I need to lube some things. I don't have an owners manual, so I'm kind of lost in that department.

Any help would be appreciated. Thank you.
