I have an Bravo 250 (I think it's a 1992).
This is my very first sled and know very little.
The problem I'm having is starting.
Before the weather got cold the sled started fine.
Now that its cold out I cannot start it wiyhout some starter fluid (of course I use the choke).

When its warmed up it starts fine.
The question I have is should I install a primer pump,I have seen these things but don't know where(or how) they attatch to the carb.


Also I was told there is a shim kit for the steering(its all over the place)
Is there anything I can do to tighten it up??


Sorry for all the questions,like I said its my first sled and having a blast with it (got it mostly for the kids).I will get a new one next year.

Thanks
Ed
 
Clean the carb, as it sounds like the starter circuit is not working. Technically the "choke" lever does not choke the intake, but rather activates a fuel circuit in the carb that supplies a richer mixture.

Yes the shim kit is widely available including at places like Shadetree, Dennis Kirk, JR Grahams, etc. It does help a lot, but you may also have too much ski pressure in front of the spindle. See the tech pages at TY.com
 
How does this starter circuit work (if its not a choke)?
When I flip it on when running it does bog down the engine.

I had looked at Shadetree, Dennis Kirk, JR Grahams, etc and all they have is to pump,ball primer (and not the spray-connector that hookes to carb.).

I thought I was on the the tech page (where are they at??).

Thanks
Ed
 
The starter circuit is nothing more than a plunger that when engaged opens an extra fuel circuit that richens the mixture. Just remove and clean, however it does sound like it is working.

Adding a primer is just a bandaid, as it doesn't address the real problem.

Clean and adjust the carbs, and check the carb boots for air leaks.

Sounds like it is too lean.

+++This may sound stupid but, are you flipping the choke lever to the second position? I have a few older enticers and if you don't put the choke all the on it will never start. I never have to touch the thottle either.
 
I too don't mean to confuse the issue but, could the fuel pump be responsible?.... Not really sure where it's located on this ravo, just remember what a nightmare older sleds were for us.... ften a pump issue....

My two cents...Good luck...
 
Bravo 250 Help

As suggested I cleaned carb.
The sled starts on 2nd try -GREAT !! (But its 45* and very warm-I will find out if it EVER gets cold again !!)


BTW:
There is no 2 positions on choke - just plastic rocker (that pulls a enricher valve ?)

ALSO:
I am about to change a clutch belt (its frayed) and would like advice on how the best way to do it. Do you have to remove the pulley on the crankshaft?

Thanks Again
Ed
 
Sorry, I thought it was similar to the enticers which have the rocker choke that moves 2 positions.
You should be able to twist the secondary clutch open by hand which would give you enough play to remove it.
