I rebuilt my 4160 and it was really pretty easy. I can't imagine the 4150 is all that different that it would be any more difficult. Just make sure you don't lose anything. The hardest part for me was removing the old gaskets. I bought some gasket remover at Advance auto that helped a lot.

Holley is the easiest carb to rebuild. I have done it several times down through the years. Just make sure you get your floats set level.

Um, pksier, did you set your floats level w/ the boat on angle ie. like when its floating, or w/ the carb level.

I set the floats with the carb level. The adjustment is more of a left/right adjustment than a forward/back which would be effected more by the tilt of the engine.

Definitely carb level, that's how I did it. The before and after results for me were unbelievable. The boat ran much better and started much easier after the rebuild.

The clear site plugs are helpful to see the float levels.

They are fairly simple to do. The Holley Techbook by Haynes is a decent reference. I have attached an article below that may help as well.

Good luck. Just go slow and make sure everything is spotless.

Hey All,

Thanks for all the responses...I think I've gotcha on the float level deal - I've got the tech book, several articles on "how to", the tools, the time and a rudimentry understanding of the job at hand...now I guess it's a matter of getting out there in the "lab" and making it happen.

Thanks again all

Wes

The floats sit in the fuel bowl in what is basically sideways to the carb. One connects on the right and the on the left inside the fuel bowl with the free end of each float facing each other in the middle.

While on the subject of carbs I was curious what size power valves every one put in their carbs when they rebuilt them.Mine had a 8.5 reduced down to a 6.5 rebuild kit came with a 2.5.Found a few problems with mine,no gasket between choke and the main body and the secondary butterflys were out of adjustment.
