Hi Mike, I thought that was a pic of bghert's set-up, I have the same looking bracket on mine, just with a longer tail and more holes, good job on the fabbing, it looks just like my eddie marine special, sorry about the mix up.

OK, I'm starting to catch up, you made the bracket that attaches to the carb throttle plate bracket, not the yellow cable bracket, correct? Is that a quick fuel 4500 carb?
Larry

Yes, The reason for the three holes. Adjustment. Some of the stock merc. setups have piece for the increase.

I did my adjustments at the throttles/shifters with stops vs. at the carb. This gives you a positive stop with no pressure on the carb linkage. Also, I personally like the shorter throw.

Yes to the bracket. Carb is a 4150, custom built by Tim Zepp engines in New Jersey. Body is a Pro Form with anular boosters .Metering plates and throttle plate are billet.

Here is a pic of my current linkage. I do not see anymore room for adjustment and I am annoyed with being WOT with the stick half way.

I had the same problem. Look at the pic in post #6. Click on it to make it larger. You will see the the Alum. Piece I made and bolted it to the carb linkage to extend the cable out fruther. You need to move it about 3/4 of an inch. You'll have to play it a little. Not very hard.

So if I am looking at it correctly the alluminum piece is bolted tot he original location of the throttle cable and simple extends the mounting location another 3/4". I am pretty sure I simple minded redneck like myself can figure it out. Did you have someone make that aluminum piece for you, it looks like it was machined.

I would not mind having the shorter throw, but i have hardly any movement before I am WOT. It is very annoying when I am trying to cruise at 3000. Your setup looks killer though!

I have the same problem after going from a Holley to a barry grant. WOT is at half. I get a ick out of the looks I get when I'm doing 70 and people see the throttle at only half:D
