getting real tired of carburetor

jimsbuddy · 04-08-2009, 03:14 AM

Ok, this is the second winter where I get ready for springers, or early Feb/mar boat usage and I loose a carb. I mean one carb is plugged and I drop a cylinder making it a 3 cylinder 50hp yamaha. Obviously Im not using the boat as often as I think I should to keep the fuel runing thru and the boat is sitting. What are my options for winterizing the carbs? Can I just run the carbs dry and leave them empty so that the fuel wont crystalize and plug up???

You might want to do what I do. I use a stablizer like everyone does, but every few weeks throughout the winter months I pump my bulb and make sure that nothing dries out. I also turn my engine over a few times at the same time. I never have had a problem in my lifetime of owning boats and that's over thirty years and some of those years I never used a stablizer!

sounds like keeping the bulb pumped and the fuel line maintaining pressure is your fix... I have had issues when I try to start the boat and the bulb never gets hard consistantly.... I have often thought about putting an electric pump inline to cure that issue

Doesn't hurt to drain the bowl of old fuel every month or two and pump new in with the bulb.

Just-in-Time · 04-08-2009, 09:45 PM

just drain the carbs after each use

jimsbuddy · 04-09-2009, 02:30 AM

Draining, was my thoughts also, I didn't want to dry them out and the gaskets start cracking and leaking...

fishkisser · 04-09-2009, 06:58 AM

I have treated my fuel for my inboard and kicker year round with Stabil since my boat was new in 2006 ...
I change the water separator filter once a year and have never found any huge amount of water ever ...
I have never ran my T-8 out of fuel for storage and it has always started no fail as does the 350 chevy inboard ...

That's exactly why I do not drain my carbs

What Gaskets? There are no gaskets in those carbs. Yamaha recommends running all carbs dry at the end of the day. Put in a 10 micron fuel/water seperator filter as well.
Store your tank either all the way full or empty.

jimsbuddy · 04-10-2009, 03:01 PM

What is that rubber thing around the base of the carb between the bowl and carb main body??? Thanks for the tip though, Im going to start that

smalldog · 04-10-2009, 03:12 PM

That is an O-ring.
Gaskets are made of a material that will dry out and crack.
Even what Yamaha calls a (cover gasket) is made of rubber and does not dry out.

jimsbuddy · 04-10-2009, 05:55 PM

Yea I know its an O-ring, black viton to be more precise. However I pulled off the carbs today and found foreign material in the carb #4. It was in the jet. Hence the reason I have a 3 cyl instead of 4 cyl, no fuel. I am thinking my issue was not with a gummed up carb from sitting over winter, but rather a dirty carb from faulty fuel filter. Im wondering why my little strainer filter on the side of the engine block didnt catch it. oh well

thanks to everyone for there input

fishkisser · 04-10-2009, 06:07 PM

Glad it was a simple fix ...

Guess its time to install a better filtration system than the stock one ...
An inline canister type filter would catch more particles than the little strainer filters ...

I leave fuel in the carb, keeps the floats from banging around during towing. Either you need a filter or perhaps clean out or replace your tank. I have had zero problems with my motors for years in that regard, and I don't use fuel stabilizers except for wintertime storage and I always try to fill my tanks after a day fishing to keep the tanks full. Ethenol is a effective cleaner and will find any varnish or gunk that may be hiding around.

Chrome Bumper · 04-11-2009, 07:51 PM

I have a Honda, the jets in it are tiny, a tiny bit of varnish and a cylinder drops out. I have a cylinder dropping out at idle now. I hope your Yami is easier to tear down than my Honda. Is there a drain plug in your bowls?

Maybe spray some cleaner in the drain, and new filter.

Use some fuel conditioner next year.

jimsbuddy · 04-12-2009, 04:36 AM

thanks Chromer... Yes these carbs have drains, but the faulty carb #4 is at the bottom and kind of behind the cowl of the motor housing. I cant really get to it to drain. I already pulled the carbs, cleaned out the foreign material, and ready to go back on. Test drive this wednesday at local Hagg lake for springer fishing on Thursday...

BassinFever · 04-13-2009, 09:47 AM

If I had to guess, the little piece that plugged the jet came after the filter from a fuel line starting to come apart from ethanol fuel! I would replace all the fuel lines!

Just a thought!!

jimsbuddy · 04-13-2009, 07:33 PM

well it just so happens I have had doubts about my ball primer. I can pump and pump, it gets hard, then gets soft again... Never really getting good and firm like an apple. Only soft like an bag of jelly. I also have a new fill spout for the main tank, and needed a good reason to install. I think it might be time for fuel supply overhaul. Anyone ever use an electric fuel pump??? I have tossed the idea of using a low psi electric fuel pump. Possibly with a adj regulator. I need to fire up the motor with a pressure gauge and see what the motor puts out normal to the carbs.

ondarvr · 04-14-2009, 08:47 AM

What would the reason be for an electric fuel pump on an outboard. The bulb isn't supposed to say hard after the motor starts and it may bleed off pressure very slowly if left for a period of time. If it won't pump up to begin with, then the problem is a leak in the system, bad check valve in the bulb, or bad float needle. An electric fuel pump won't fix any of these issues, only create huge problems if the float needle or fuel lines leak and then pumps gas into the boat.

Hunt'nFish · 04-14-2009, 01:41 PM

Do you pull the fuel line and run/burn the fuel out of the carbs when you put it back on the trailer?
If not, do it.
Hard for fuel to go bad & plug your carbs if there is no fuel in them to go bad.
I always pull the line & let my motors run until they die.
Never had any issue w/ them.

For winterizing, you could fog them.

Only to not have to pump the bulb when I want to fire up the engine.

I never said anything about being hard after starting the motor... this happens when im priming the engine to start.

agreed

The Tempo squeeze bulbs have quality problems. I went through 3 of them before I found one that actually pumped reliably. Tempo is out of business now. I haven't had problems with the Moeller bulbs.

thanks, I will look for that one
