1995 FastStrike leaking fuel

[pumfe]

Hello, All! My motor is leaking fuel out of an orface of one of the carb bowls. I thought maybe it was a check valvle where the BB looking ball is no longer there. I noticed it this weekend when the motor would turn off because fuel would run out in a steady stream for a few seconds. I did notice that this would leak a little bit previously, but that was when I would squeeze the fuel ball to prime it prior to starting (would leak around the ball in the orface). Now the ball is gone! It also leaked out of the top of what I think may be an electric fuel pump that is located at the front of the motor, but this again was only when squeezing the ball with the engine NOT running.
The new issue is the major leak out of the one carb bowl when the motor turns off. Can I replace just the bowl portion of the carb?

Pics attached.

Thanks in advance!!!

Phil

Yes...........

Thanks, Boobie,
I was able to buy the bowl, and the parts salesman talked me into buying the carb rebuild kid. It looked simple enough so I rebuilt the carb, but now when I give it full throttle, it hesitates a bit when getting up on plain, and it goes about 9MPH slower than it did previously. I didnt change any adjustments; any thoughts on what may be making it run like this?

Re: 1995 FastStrike leaking fuel

Did you get the high speed jet reinstalled correctly in the new bowl and was it clean ??

Re: 1995 FastStrike leaking fuel

Everything was very clean; no build-up or gunk. Not sure what the high speed jet looks like. The kit came with a new float and needle, the gaskets, and the "bolt"with the hole in it that the needle seats into. It seems to me that maybe the float adjustment isnt correct... i feel like it hangs a little lower than the original one did, but I am clearly no expert. Other than replacing these parts, I made no other adjustmetns anywhere on the motor.

Re: 1995 FastStrike leaking fuel

i wonder if you had a lean condition that gave you a little more HP than your current NON lean condition....

the high speed jet is under the big brass screw on the front of the carbs.

there is no adjustment for the high speed jet... you just clean it and install it...

i have rebuilt a few of those carbs and I swear , that i am thinking that i was confused about the 'washer' under the float needle seat, being there or not when i dissasembled the carb..

its in the rebuild package... and will have an effect on the float adjustment for sure.... but i think i remember the washer NOT being there on dissasembly

in any case if you set the float to open and close per instructions.... you will be fine.... I was

if you just reinstall as it was before....you might have issues, if you used a washer( gasket) , where there wasnt one before...

how much were the carb bowls??

were they plastic or metal?

thanks

Re: 1995 FastStrike leaking fuel

That gasket was used in the old looper float bowls. If you look closely where the seat fits into the bowl and you see rings, no gasket is needed. If there are no rings and it's just flat you use the washer.

Re: 1995 FastStrike leaking fuel

There was no washer on the carb when I took it apart. I did wonder if it was supposed to go on there or not, so I tried it. The motor would kinda rev up and down, so I took the washer out and now have the problem of lost power at high to full throttle. There was not hardly any play in the float when the washer was on there, and without the washer, I feel there is too much play. I cannot find anywhere online if there is a measurement that the float should be at with the bowl removed. There were also no instructions that came with the kit on how to set the float to open and close; the only documentation that was included was a sheet telling me which gasket to use with certain models.
I pretty much just screwed the brass threaded hollow bolt into the carb, assembled the float and needle, and put it all back together. There is a philips screw that holds the pin that keeps the float in place; i'm not sure if that can act as an adjustment or not. I read somewhere else to bend the float bracket to the specified angle, but that sounds scarey to me.


Bob, I paid $22 for the bowl and $27 for the rebuild kit.

Re: 1995 FastStrike leaking fuel

here is the explanation from my 1995 115 60 degree looper manual

so with the float forcing the needle into the seat, you need to adjust the float off the carb housing so that the surface of the float is level with the surface of the housing...+ or- 1/32"

then you tuen the carb over and let the float hang away from carb housing and that measure should be 11/16th" to 1-1/8ths" ( large tolerance!!! easy peasy)

good luck


your issue maybe you just installed the float with out adjusting...

you will need two sets of needle nose pliers to bend the float TABS on the metal hanger.... DO NOT force the floce down ward pushing the needle into the seat!!!!!!!!!! you will mark the rubber tipped needle

use two pliers and then see what the setting is.... and readjust with pliers and see what the setting is....

one adjustment is the bending of the large metal surface of the float arm...the other is the almost 90 degree tab bent off that arm!!!

its there for a reason!!!!! the tab adjust the large setting when the float is hanging away from the carb...

bending the large flat arm adjust the "flat = or _ 1/32" setting!!!!

whew...good luck

Re: 1995 FastStrike leaking fuel

Thank you so much, Bob. I think I can figure this out... I'll let you know if it worked after I test it this weekend. Below are some pics just so you can see what I was working with. I didnt see the 90 degree tab you were referencing though.

in the first picture you look like you are adjusted way to high!!! there shouldnt be that much of an angle in the light between the float and the carb surface...

here is a picture of the 90degree tab!!

as far as i know all floats have this.

the 90 degree tab is used to adjust the float drop...( the large measurement)

good luck

Re: 1995 FastStrike leaking fuel

Yes, those are pictures of what everything looked like when I installed it initially... I haven't made the adjustments yet. I think it's safe to say that that was my problem .
I also looked a little closer at the float and found the tab on the underneath side...
Thanks again, you've been a tremendous help!!
I will let you know how everything works once it's reinstalled and on the water.

Re: 1995 FastStrike leaking fuel

Did you get the high speed jet reinstalled correctly in the new bowl and was it clean ??

If you look at the carb with the front facing you, as it would if it was installed on the motor, you will see a large brass drain plug near the bottom of the bowl. The high speed jet is behind that plug. I doubt( but can't say for certain) that the new bowl came with a jet installed because there are many different sizes for the various models and HP of the engines they are used on. What boobie is saying is: Did you remove yours from the old part and reinstall it in the new part? If it did come with the main jet installed, is it the correct one? The high speed jet does not come in the rebuild kit either.

Re: 1995 FastStrike leaking fuel

Uh oh... I did not take anything out of the old bowl aside from the drahin bolt... and of course I already threw the old parts out. Grrrrr. So I guess I have two problems; the high speed jet, and the float adjustment. I ordered the part below... I hope it's the right thing.

0327558 ORIFICE, High speed, #69D, 115

Thank you all for your help... I love this site!!

Re: 1995 FastStrike leaking fuel

Did you look to see if the new bowl had one installed? You can remove the jet from one of the other carbs to check the size. It just unscrews. It should be stamped on the jet.

Can't tell you if that is the correct part number. The orifices and jets can be different depending on the model number.

Re: 1995 FastStrike leaking fuel

The new bowls DO NOT come with the jets in them. Shame.:grumpy:

I just checked the parts break down and it looks like you ordered the right jet. Check the top secret files at the begining of this forum for making the correct screw driver to install the jet. It's a special one.

Re: 1995 FastStrike leaking fuel

Gents, I took the boat out for the first time last night and it worked perfectly!!! Thanks to you all for your help and guidance! It's truly appreciated!

Glad you got it. Next time it will be simple.
