I have a 1990 Volvo 570A (GM 350 block) with original Holley 4150 style carb with the stock volvo throttle cable. Carb was going downhill so instead of rebuild for $350 I decided go brand new for $450 so I bought a new from Holley Marine Avenger 4150 style carb 670 CFM.
My 33C cable appears to have twice as much throw and can't connect to the carb for idle. On the phone with Holley they say they are set up for a Mercruiser style cable, not the 33C from a Volvo and I should buy a new control box. (ha ha ha) I bought the $60 bracket and it's no different than the stock cable setup, it looks like my 33C cable is going to be too long no matter what. I have a Heim end (ball joint), but then my controls can only start at 1/3 throttle to about half throttle for WOT.
I sawed off the old volvo bracket with the little copper spinner block, but it doesn't seem to fit on the new carb throttle plate.
Anybody have any ideas how to get the 33C throttle cable working on the new Holley carb?
I thought about getting a piece of sheet metal and cutting out something like you see in this photo, but Hardin marine doesn't sell this piece highlighted by the red arrow. It looks like I might have to make my own makeshift version.
Thanks in advance!
Here is a photo of the original throttle bracket that goes on the old carb.
