I want to provide a solution to the 125BV blower. I determined my similar symptoms were a fuel issue. I found the gas cap was not allowing air into the tank as the gas was used up; thereby creating a suction where the blower would not intake gas. When I loosed the cap, problems solved. I plan to get some carb cleaner to clean the vent in the cap. A very easy solution to all the problems I am seeing, like mine, on the web.

Do you have a push mower, leaf blower, string trimmer, etc. that wont run; and you dont know which direction to go to fix it? The majority of problems are fuel related and this is a fast, easy way to determine if it is or not.
Start be removing the air filter and verifying that the choke is open ( run position). Then, spray a shot of carb cleaner ( available at any auto parts store, wal mart or dollar general) into the throat of the carb. Attempt to start the unit. If the unit hits on the prime ( starts and runs briefly on the carb cleaner) then the problem is fuel related. You should check your fuel ( water or stale), fuel lines and filter, and carb. If the unit does not hit on a prime then you should start checking your ignition system and compression.
Most snow blowers do not have air filters. They tend to clog on these units. Sounds like your issues are fuel related. You may try to flush the system with a product called "Start" from Wal-Mart. You will need to follow the instructions on the bottle and try to keep the unit running long enough to run this cleaner through the system.

You might have more than one problem...first check the IAC (Idle Air control) valve located on the intake plenum, if possible pull it out and spray it with choke/carb cleaner. I'm guessing you are hearing the fuel pump coming on when you turn on the key...if you don't know, check it. Key to on (not start) and the fuel pump will bring up the fuel pressure and cut off.
I haven't had experience with the '98 but those caravans are known for having dash problems...occasionally it requires replacing the cluster, if you are lucky you may be able to reseat the cables going to it (or try gently moving them around). Your symptoms are a little confusing since you say they won't power up...do you have movement in the gas gauge at all? I had one that had similar symptoms and if I smacked the top of the dash everything would come on...worth a try just to see if anything changes...just don't hit it hard enough to break anything (or hurt yourself obviously).
Since the van is starting I would rule out the relays (and fuses)...and it's running too long for it to be the cutout relay (loss of ignition, which cuts off the fuel). If you give it some pedal (gas) will it stay running? If so, do the IAC thing...so try to determine if it's a idle only problem or it just dies in general
cut the new fuel line down to 1/3 it dia size about a 1/2'' long slide a stiff wire threw the hole and out threw the gas cap opening slide the hose over the wire and pull it back till the hose comes threw put the fuel filter on and pull it into pace
Nephew had similar problem on different vehicle - had spark to plugs, limited gas, everthing else checked. I did one thing first - check for two fuel filters - one in the tank was only screens and one in the line itself. Found a little in line filter just outside of engine compartment under car next to frame that looked like it had never been changed - partially clogged - replaced it.Almost ran but would not keep running. I had rotor and cap pulled - found that the screw holding rotor in place was loose. The rotor edge next to plug wire leads was chopped up and the cap's plug wire leads were heavily oxidized. Replaced them and got it running but a little rough. Pulled the spark plugs and found gaps from 25 - 100 ---replaced the plugs with correct gapping and it ran really well.
All of these "starting/running" issues are similar and related directly to one cause. It was suggested several times that the muffler may be plugged, but mine was found clean during a complete teardown. Cab cannot be blamed either, since the fuel filter wouldn't be able to pass anything large enough to foul an orfice.
Very common issue with hot running two cycle engines...ring fouling and loss of compression. The brand or type of oil must be scrutinized, and the mixture kept exact. I would never use anything but Echo or manufacturers recommended oil in these units ever again.
