Might be some crudded up gas.  I just started mine up after sitting since Nov.  I put in some Sta-bil before storage though so it just took some twists of the throttle and 30 secs of having the starter engage.  Check for gunk in the carbs and you should be fine.

I don't know why, but a good shake seems to ward of the gremlins. :lol:

love taps
« Reply #3 on: May 08, 2005, 01:45:34 AM »
yeah some others said just tap the carbs and maybe you'll get lucky
so i tapped the carbs nice like
and it actually choked up some black smoke but wouldn't stay fired up

i think that is grounds for a full carb clean
but probably better to go ahead and get them professionally done
I'll get some new plugs too

as far as the gas its brand new 91 octane
i kept the tank off and empty and kreemed
so nothing got corroded or stale

I really wish I'd taken pics of mine before I had them cleaned...

They were worse than that. A -lot- worse than that.

Sounds like it might not be getting gas.  Kinks in the fuel or vac lines?  Do you have an in-line fuel filter that might be clogged?  :headscratch:

Did you fill your float bowls by setting your petcock to prime for 30 seconds??? How did the o-rings look in your carb???

i'm not an expert on carbs
« Reply #10 on: May 11, 2005, 11:47:57 PM »
i cleaned them goodonly had a tiny bit of gunk on the bowls
the o-rings seemed good no cracks or mushes but i'm not an expert
the needles looked good too I think from what the
manual says they should look

also all my hoses are in correctly nothing pinched
although the tank's water avacuating hose always seems to get
slightly kinked no matter what position i put it in

so here's the situation now
after priming the tank and letting the
bowls get to a proper level -30 seconds or so
then put the choke either full or half way
then hold the throttle open
I start her up and if i hold the starter button in
it turns over almost sounds like its running with a few pops
and i get excited

however 1 second after i release the starter button
she fizzles down to nothing full stop

what am i doing wrong!

the engine is moving
i'm actually leaking/circulating oil now
i think i kinked my gasket on the left side

Still sounds like no gas.

1. Try draining a float bowl to make sure you've got gas in it. Your fuel filter could be clogged up with rust.

2. Did you clean all the jet's and passages when you cleaned the carbs?

3. Are you getting compression?

petcock
« Reply #12 on: May 12, 2005, 02:08:18 AM »
if i pull the fuel line off the feul-cock
gas should just spill right out correct?

thats not happening
the petcock looked fine and clean on top
where the little filter tubes sticked up into the tank
i'm wondering if there is rust clogged on the inside

is there any way to clean or test these?

Incorrect... unless your petcock is selected to prime. The petcock requires engine vacuum to open it.

Drain the tank (or at least tilt it to a position that all the gas doesn't spill out when you do this), remove the petock from the tank and inspect it - and clean it, if needed.

well the tank is clean and kreemed
and there is fuel in the float bowls
will a hand pump from a syphon
have enough power to suck fuel
out of the fuel cock?
the petcock is visually clean on the outside

the b400 has only on and reserve
so it is vacuum only
thanks for reminding me
i remember reading that
from an old post
