You should be able to remove the old one with a screw driver or needle nose pliers. The new one should have a new gasket with it.

The jet in the carburetor is clogged if it is a 4 cycle unit or the diaphragms are stiff if in a 2 cycle unit. It is burning the primed fuel but can not draw any more fuel to burn to stay running.

SOURCE: I have a yard machine

Your carbs main jet is blocked. Using the primer supplements the fuel input and keeps the engine from becoming fuel starved.

You need to remove the main jet and run a strand of fine wire through the jet to clear it.

SOURCE: 21A-121R900 Won't stay running

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, ~~

If the carb is new, then make sure the fuel is fresh- LESS THAN 30 DAYS OLD!!! Is the plug good? Air filter OK? Good oil in the engine? Make sure that the shut off cable hasn't stretched. It may make contact and shut off the engine.

New honda hrr auto choke hard to start


sounds like it may need the carb clening out, but it could be the auto choke not closing when cold. there was an issue with some of the early auto chokes on the gcv135/160 engines so check to see if the choke flap is in the closed position when starting from cold, run the engine for approx 10-15 minutes and see if the choke flap has opened fully.leave it to go cold and see if the choke flap has returned to the closed position

on the side of your mower by the exhaust, there should be a plastic cover about 2"wide by 3" long, inside of this is your air filter take it out & clean it with a air blow gun, or tap it until clean, see if that helps.

Won't stay running


Check the gas cap vent. A partial vacuum in the tank will cause these symptoms.
