Ok so I have a 4.3 Volvo penta and have been experiencing hesitation on throttle up and dieseling when shutting down. Took it into the shop and mechanic diagnosed carb issues so a carb kit was ordered. Today I received a call and was told that the whole carb needed to be replaced due to the interior lining peeling away from the carb and flakes blocking the jets.

Was told that they have never seen anything like this before and could not explain how this happened. So my question is, anyone ever experience this? If so can the interior of the carb be sandblasted to remove the factory coating? New carb $1000.00. If I knew anything about engine repair I might attempt it myself. Once I get the bad carb back I will post the pics.

There is no "interior lining" except the cadmium coating. The rebuild kit includes new jets, who cares about the blocked ones. Gas can not remove that coating. What happens is when you let the boat sit with gas in it for extended periods of time (6+ months) the gas coats everything in a thick film of varnish it's nearly impossible to clean but not impossible when soaks for a few days. You can let any gas made sit in there for 20 years and it will not remove that plating. It's chemically impossible.

That engine should have a 4 barrel on it. If not I can get you the part numbers for the 2 barrel. The good news is, a new carb is not $1000. It's only $425. IF not, the 2 barrel is even cheaper.

The rebuild kit is $25 http://www.race-mart.com/Holley_Perform ... 03-29.html

EVEN better news is: Give your mechanic the middle finger, hook up your boat and tell that dishonest cheat to go suck himself. Buy the rebuild kit for $25, do it yourself it's easy. It will run like new. In a rare instance if you did let it sit and it's all gooped up, take it all apart, stick it in a bucket of carb cleaner (buy it at NAPA) and in a few days scrub it down good with a wire brush and install the rebuild kit. Will run like brand new.

Welcome to the forums

PS, get used to installing refresh kits. If you use your boat weekly, you can do it every 1-3 years for optimal performance and gas mileage. If you use your boat every 1-2 months, do it once a year to avoid downtime of clogged holes from gas varnish. It's part of the maintenance schedule of owning a boat with a carb. Get used to it. If you run pump gas E10 throw a main jet in that's 2 sizes bigger then stock, it will run even better then off the showroom floor.

Yep they are claiming that "coating" is bubbling and separating from the body. They are going to show me this in the morning.

I did find this http://bit.ly/PXQXrx

Not sure if this applies to my engine but I am looking into it.

Thanks for the info. I should cancel the service. They had to order the carb anyway. Sad thing is they have had the boat since July 5th.

I have to agree with this:

" Give your mechanic the middle finger, hook up your boat and tell that dishonest cheat to go suck himself"

I doubt you have a 4bbl.

You're right, after a bit of searching they seem to be using the 500cfm 2bbl holley.

$299 OBO factory refurb direct from Holley. http://www.ebay.com/itm/350582015242?hl ... 296wt_1163

Not sure what jets will be in there, but the 4.3GL requires a #70 main jet and a 2.5 power valve.

For that price, I wouldn't even bother rebuilding your current carb after that idiot put his unskilled hoofs all over it. If you were in Florida I'd help you install it, takes about 30 minutes (don't forget new gaskets) and you'll be on the water running like new.

" Give your mechanic the middle finger, hook up your boat and tell that dishonest cheat to go suck himself"

Absolutely. $1000 bucks for a Holley 2bbl??! I'm new to boating, but was a hot rodder in my youth and I would have fell down laughing when your mech told you that.

Shoot, we used to build entire engines for racing for less than $1000....(of course that WAS a few years ago). Ric is right tho, rebuilding a carb is not that hard, just go slow and account for all the little parts!

For 299 or best offer, don't even waste the time rebuilding it. Just know that in the future if you know it's going to sit for longer then a month-- drain the gas out of the carb. Takes 5 minutes and it guarantees this won't happen again.

Took a look at the carb this morning and and grabbed a few shots.

The top and the left sides are showing the deterioration.

The $1000.00 includes the labor for tearing it down, replacing and testing. If I knew how to do this I might attempt it but I guess it's more important to get it back in the water, it's already been down for 3 weeks and if I attempt it maybe the summer.

Looking into the recall angle too.

Dude, it's 4 bolts, a kotter pin, and a clamp for the fuel line. If my 100lb 27yo ex-wife can change the brakes on her BMW (WAYY harder then a carb swap) wearing heels and a sun dress you can handle 4 bolts. Tell that man thank you have a nice day, get your boat back.. and by next weekend you'll be playing on the water for $300. It literally takes less then 5 minutes to take the carb off the boat. Another 5 to put it back on using only 3 tools. A hand wrench (1/2in probably), flathead screwdriver, and a pair of pliers.

Ok took the advice. Told the shop to cancel. That was a battle in itself. At first they told me I couldn't cancel then they wanted to charge a restocking fee. Finally we agreed on 150 for their time. I hope they gave me all the parts because what I got back was a box full of stuff. Hopefully I can figure out where it all goes, looks like its book buying time.

Bought the carb in the above link was able to get it for 250.00, looking for the rebuild kit for the 4.3gl-d which I believe has the proper jets and gaskets.

Thanks for the input.

Good Call!. Those idiots are working on margins that make the banks and casinos look like upstanding citizens, I have rebuilding Holley, BG, Quadrajet, Rochester etc. carbs for so many years that I count the parts in them instead of sheep when I go to sleep. Usually have time between rounds bracket racing to rejet the entire fields carberators. The 4-1/2"bolts and gasket, combined with the fuel line/s take only seconds to change...minutes if your extra careful. Do take CAUTION not to overtighten anything and manage/plan for spilled fuel by controlling it (plastic coffee tin cut don as a catch pan). Pickup a few sets of extra bowl gaskets and some extra jets, to give yourself some tuning ability, always check for leaks after assembly and...give those idiots the finger!

Suggestions on a reliable place where to get the gaskets from? Been looking fr a bit and can't seem to find it. Does the 2300 500cfm carb come jetted at 70 like the Selok book calls for or do ya think I will need to rejet. The description on the carb just states universal marine calibration.

I assume once this project is complete I will have better knowledge but today I ask from those who know. Thanks

That's a crazy price, I got my Rochester Quadra Jet rebuilt by a very good local mechanic for 160 a couple of years ago and the Q-Jet is a much more complex carb than that one. R+R a carb is not difficult. The rebuild part, takes some skill and experience.

The mechanic used a standard OMC gasket kit to do the rebuild.

pull the bowl off and look at the number on the jets, and the power valve has a number on it al well. then if they are wrong just order the 2 jets and a power valve from any auto speed shop or go on ebay.
when I was playing with different jets on my sundowner with that carb I went out with 5 different jet sizes and different PValves and changed them while on the water till i got the performance it should have. I got them all from Advanced Autoparts. they were dirt cheap
