Question about Briggs & Stratton Briggs Stratton 2550 Psigaspressure Washer

1 Answer

Won't start I have checked the spark plug and I have good saprk. I have checked the fuel sysstem and the primer bulb injects fuel. I have removed the head and cjecked for engine damage and all cycle correctly. Vaves opne on time piston shows no dmagae. side walls are smooth and not damaged. This engine was working fine but the pressure washer needed some O rings replaced. I have tried to start it with and without the pump attahced. Evrything on the engine looks fine. I removed the spark plug and laid it againist the housing. When you pull the starter it has great spark. I replaced the plug and sprayed starter fluid in the intake manifold. When you pull the starter it rotates smoothly but won't start or even act like it.

I could be the timing is off.
You can check it with a feeler gauge.
Place a 0.08- to 0.012-inch feeler gauge tool between the flywheel magnet and ignition armature legs to adjust the ignition armature air-gap for proper ignition timing.

SOURCE: pump leaks not to much pressure and when i you the prime pump

Hello rr61
If the pump is leaking you will not get pressure. You need to get the leak fixed. Where is it leaking from?
Leaning back to star and run sounds like the motor oil is low. You are "tricking " the low oil sensor. I would change the oil and be sure it has the correct amount.

SOURCE: Engine wont stay running

It is a diaphram carb. Doe's the primer **** straight gas or does it have air bubbles in it? If it has bubbles in it then it is a leak in the fuel line.
If not then Unhook the intake fuel line and pump the bulb until all of the gas is out of it. Then pour the gas out of the tank and rinse it out with new gas. Pour in new gas and it should be ok.

Ryobi 410 mini tiller w/Walbro WT149A primer bulb won't prime. New bulb, new fuel lines, hooked up right, carb cleaned. Been sitting for several years.Runs when fuel is pumped into the fuel inlet.

hello sir, my machine will only start when pumping primmer bulb or squirting fluid in the carburetor than stops. the fuel line has broken off, in most small carburetors this is a ongoing problem.old fuel will crystallize when left in tank for a long time.plugging up ports, fuel lines, small screen in carburetor.fuel lines will dissolve clogging carb.this is why it will run when the choke is on creating a vacuum to where there is fuel forced in the carb to rum,also the gas will evaporate leaving the oil behind clogging up carb.the thing to do is remove carb. and clean out,replacing gaskets or fuel line if necessary.use carb cleaner to clean out carb.make sure to make note where fuel line go.the fuel filter broke off of fuel line letting debris get in carb plugging it up.the muffler is known to clog up a lot on these machines where they want run. the compression should be 60 to 120 lbs any thing below 60 is junk. when adjusting the carb screws turn in all the way than turnout 1 1/4 turns turn in slow until machine runs also you need to check for spark by removing plug and grounding against engine to check spark, ok.a new spark plug would be a good ideal too , if you are going to make these repairs use new fuel line and filter,hope this helps,any comments welcome,thank you, !!

Mantis tiller will not start. Cannot get primer bulb to draw fuel.I replaced all of the lines,primer bulb still won't work. Tiller will start by priming cylinder by removing spark plug. Help?

Make sure there are no leaks in the bulb. Did you reattach the fuel lijnes correctly? You should feel resistance after pushing 3 or 4 times to ensure fuel is getting to the carb. If necessary replace the bulb. Otherwise check with Mantis at or give them a call for troubleshooting assistance.

Will not start

After 3 years, the fuel lines may start to decay and the fuel filter in the tank is likely to be plugged. Check the air cleaner and muffler for plugging also. Remove the spark plug and check for spark which should be blue and snappy. If nothing, try a new plug gapped at 0.020". A properly running two-stroke plug should have a light to medium tan color on the interior insulator. A black insulator indicates an overly rich fuel mix or jet setting. A white insulator is either new or running too lean which will damage the piston and cylinder if allowed to continue to run. If you get spark, pour a little mixed fuel into the plug hole and try to start the engine. If you get a few pops, then concentrate on the carburetor and fuel feed. Does the primer bulb bring in fresh fuel when pumped? If not, is the bulb itself damaged or hardened? The primer is supposed to pull fuel through the filter, into the carburetor filling all spaces inside, then out to the primer pump and the excess returned to the tank through another line. Hope some of this helps!

Won't start

drain fuel tank. keep depressing the primer bulb until it is clear. drain tank again. remove carb cover and disconnect lines one at a time. keep depressing primer bulb to get rid of excess gas. remove spark plug an turn engine in a position that the spark plug inlet is facing the floor, pull starter rope a few times to get rid of gas in the engine chamber.
