Motor rebuild

[Cholder2003]

Quick question I just had a complete rebuild of my monsoon 335 I upgraded the can to a Elgin e-1135-p cam, new plugs,wires,coil pack, relays, everything new. And I can’t get it to idle on its own with out throttle. Talked to a couple people and they tellin me I got to retune for the cam? Anyone had this issue before? And any truth to having to re tune the motor?

I'd put the factory cam back in it.

Engine is speed density. Unless the cam changes are minor it cannot compensate for it.

I'm wondering if you'll have to do a base timing set-up also.

I put a ZZ4 cam in mine during a rebuild.  Runs great but spark plugs say it is running rich.  Way better than running lean.  No reprogramming.
