The choke works great except I assume that when cold, the choke would raise the rpm until it warms up. Right now it doesn't, and will barely idle unless I press the accelerator slightly. It doesn't struggle to idle at all, it's not lean, etc. and responds nicely - the idle is just low. If it's intended to be used with the manual throttle cable that the Rochester used, I can hook that up, but if it's supposed to raise the idle until warm please point me in the right direction. Thank you, Lindsey

If the fast idle cam and spring on a 967s are correctly installed, the fast idle spring is good, and the fast idle link adjusted to specification, then the engine should fast idle.

Good carburetion is fuelish hot airThe most expensive carburetor is the wrong one you attempt to modify. If you truly believe "one size fits all," try walking a mile in your spouse's shoes!The Carburetor Shop | | | | | Joined: Oct 2017 Posts: 214 'Bolter | | 'Bolter Joined: Oct 2017 Posts: 214 |
