Didn't really work on my MC but i did receive a package from Skidim today. My 4160 carb, gasket spacer, R/W pump impeller, catalog and decal. Took 8 day to get shipped up here. Was expecting two weeks or more. Total cost was around $510.00.

You'll be happy with that new 4160. Bought a new one for my '87 years ago (tired of messing with the old one). About a 1/2 turn on the idle screw and it was dialed in. Enjoy!

Did you adjust them with a vacuum gauge hooked up?

I picked it up from Wayne Kraft

Sidebar - I give my highest recommendation for aurokrafttransport.com. great guy to work with, and FANTASTIC service.

The work done on my MC today, was to prove to the bank/lender that an 02 X-30 is worth $30,000 and not $22,000 like NADA states....they'll just never understand

The ones that skidim sells are already setup for the the 351. While using a vacuum gauge is probably the preferred practice for those who know how to use one, I can attest, as someone who wouldn't have a clue how to do that or what to look for if I did, that those carbs from skidim are (or at least seem to be) bolt on, adjust the idle, and go solutions.

Good point. Much easier to do the wrong thing with a carb if you are not well versed in tuning them than the right thing.

Installed the Fly High piggy back system, 4 new Wetsounds 6.5 hlcd's and Syn 2 amp, new bimini top, and new 4 port Heatercraft heater.

Niiiiiice! I hope my wife never finds out that you can get a boat with a heater. LOL

It wasn't very far off, but it did make some difference. They are pretty spot on but I think each engine is a little different it never hurts to tune. If you are having part throttle or off idle stumbling you might want to check and set the idle screw mixture.

I did do a high RPM plug test and they do seem to be jetted correctly for the 285/351.

That carb was probably the single best upgrade I did for that boat. No more difficult cold starts, crappy idle, dying or needing to rev it to stay running when cold.

Now that I think about it, I can't remember if I ever adjusted the mixture or not. I know I read up on it, but I think I left well enough alone. Now, I definitely adjusted the idle because it was stumbling at 400 rpm out of the box. Great upgrade for sure. I'm sure with the proper know how, I could have tweaked it to perfection. But, without that know how, the aint broke don't fix it attitude probably served me better.

Can't repeat,

No....vacuum gauge = beyond my tool/skill level. I just bolted on the new carb and gasket, tightened it down without a torque wrench, and it fired right up and ran great. On the water I made a minor idle adjustment to get 600rpm in gear, and that was it.

Nice avatar, by the way--Air Assault!

Thanks. 506th and 327th OIF IV 24 year participant.

If you are not having off idle throttle issue then they are probably pretty close.

In a nutshell, You're trying to gain the highest manifold vacuum at operating temp and normal idle speed. Adjust one side a time closing them by half a turn. If the vacuum goes up do the other side a half turn. If vacuum goes down go out a half turn checking each side and always resetting idle if it goes up or down. Both sides should be set to the same setting.
