Ok so after gett my baby out of storage and getting her worked on to get her back up and running I've knot iced that she will go and cut out when I go full throttle I have to die it back then latter on the ride after she warms up some I can go full throttle but every now and then it'll cut out on me. It's not killing the motor completely it's just as if I let go of the gas completely. I don't think it's gotta deal with the fuel system just cause it runs fine after it "cuts out". I might try to get a video of it so u guys can see what I'm talking about it's hard to describe in text.

im not the brightest on here (espessialy about 2 strikes) so dont take my responces to sereously and i no u said its prolly not the fuel system but an idea of what it could be is matbe a clogged jet hopefully a more experianced person can give a better answer of what they think it could be but if nobody responds and u run out of ideas you could try getting a new one

Could be fuel starvation because something's bunged up. Drain the old gas and put some fresh in, and give the carb a good cleaning.

I also would look at the fuel system first. Small or clogged main jet, clog or restriction, faulty petcock. The symptoms you describe are usually fuel system related.

like was said if it forst came out of storage i would start with drain the fuel replace the filter and clean the carb
then i would look at the exhaust to see if it is pluged up
clean the air filter and replace the plug

Ah yes, I totally overlooked the out of storage bit. jmk makes a good point to drain what's in there and add fresh fuel. Even with Sta-Bil it will only stay good so long. I had some fuel in my car's tank for a few months with Sta-Bil and it had a very clear odor of bad gas and that trademark brownish/amber kinda color. I heard recently that the marine formula is actually a better choice for storing ethanol blended fuels.

yeah and with stabil and the ethonal gas that just about all of us have
the gas only stays good for about 30 days(about the same if you leave it untreated)
for storage i recomend seafoam and you might even be able to try to run some seafoam thru in a tank of fresh gas and not have to take the carb off

ya i ran seafoam through it after i got it back from the shop where they cleaned out the carb changed the sparkplug and a few other things but i'm thinking maybe i just need to drain it all out and start with fresh gas i guess i didn't even think about that. how hard is it to drain all the gas out?

pull the vacuum line off the carb
pull the fuel line off the carb
and pull a vacuum on the vacuum line
i use my vacuum brake bleeder for this

Bad gas.
Sea foam. Use a cap full every fill up and it should keep things pretty clean in there. JMK is right, might not even need to clean the jets if you get lucky with some sea foam.
The vacuum line is the small one. You can use a brake bleeder, or if you don't have one, a vice grip and just suck on the vacuum line to get the vacuum started and clamp down with the vice, or you can do like I've done and get a vacuum going and just plug it with your thumb and wait it out. There's always a good ole siphon too.

When I first bought my Marshin (Used) I had similar problems and here is what I did.
1) Pulled gas tank off and dumped out what gas was in it.
2) Added about a 1/4 tank of gas back in it.
3) Added a hand full of BB's and put the gas cap back on.
4) Shook the tank several times to agitate the BB's, they will act as a sand blaster and remove any garbage build up you might have on the walls of the tank, you may want to cover the gas cap with a rag as some may fuel may seep out .
5) Dumped out the fuel along with the BB's.
6) Add another 1/4 tank of gas without BB's and shake it up to rinse any remaining material out.
7) Pulled the fuel line off and blew out with air.
8) Removed the carb and tried to keep some fuel in the bowl so you can see if there is anything floating around.
9) Removed the main jet and blew it out along with blowing out any of the other passages in the carb.
10) Use a clean lint free cloth to wipe out the bowl and the intake side of the carb. Remove the electric choke and clean it and blow out the area it seats into.
11) Use a rag to wipe out the air filter tube that connects to the carb.
12) Reassemble the carb and install it back on the motor.
13) Replace fuel filter.
14) Hook everything back up and install the tank and fill with new fuel.
By doing this you have just covered the entire fuel system and have removed any contamination that could occur.
It better to take your time and do it right the first time.
One more thing I want to add is that after putting it all back together and you still have a problem, it is possible that you have a vacuum leak.
The way I test for vacuum leaks is to use a propane torch, turn the tank on but DO NOT LIGHT IT.
While the motor is running take the nozzle of the propane tank and go around the intake manifold of the carb and motor.
If you have a leak it will suck the propane into the motor and it will increase the throttle, it will rev up slightly.
The old way that was used to test for a leak was to spray starting fluid around the area. Problem is that if you have a bad plug wire that is arcing slightly and you use the starting fluid well you are taking a trip to the hospital.
Propane exposed to the air is not concentrated enough to cause any problem as there is too much oxygen in the surrounding air to cause it to ignite.

ok so i took it out for a total of about 3 hours today and i put some seafoam in the tank and i let it drain completely out (sat in gas parking lot full throttle till it cut out lol) i filled it up with 93 and put more seafoam in it and it seems like it's running A LOT better. thanks guys we'll see how it runs tom.

Ok so I thought I had it figured out and fixed but its been doing it again. I found that when it starts to cut out on me if I give it a little choke then it'll rev right back up. I then can go and dail it back and it'll go fine after that. Its only when I get it out after sitting over night or for a few days.
