Question about Husqvarna 160 CC Honda OHC Engine 21 in

2 Answers

Carb will not shoot gas in engine w/primer.

I'm an 8th grade science teacher and also teach a small engine class. I've compiled 42 Briggs vertical shaft 3.5hp-3.75hp engines. 20 are dedicated troubleshooting engines. I think I know my way around this engine, but one problem stumps me. I have approximately 8 carb/tank combos which I have completely disassembled (diaphragm, fuel pickup tube, primer, check valve rubber, ball, spring, main jet) except for the steel balls which look like orifice plugs and not to be removed. When the tank is filled w/gas, the primer pushed, no gas come through. I've had engines do this (not prime) and I poured some gas straight into the carb, started the engine, then the primer would work. Seems there should be a better fix. Would really appreciate the info as I'm on a budget. Thank you. Carlton Ochner Stockton Middle School

Hi
oval or round form
At the diafragm part,under it, there is a technological cover(made of alluminium).Under it there are some orifficies,make conection with "Venturi"wall from the carb(three orifficies I think).Some way remove that cover and clean the small plugged holes.You need to change it with a new one.Please let me know how the things are going on.

sincerly yours savumihai71

Will not prime with primer bulb , can squirt gas in carb and get running then while running you push the primer button it chokes down the engine .


Does it stay running after you squirt fuel in the carb opening? If yes, then there may be a pin hole leak in the hose going from the fuel tank to the primer bulb and it is adding air to your carb.
Thanks

My briggs and stratton Model 12H802 engine is hard starting


hard starting on small four stroke engines is often related to valve clearances closing up due to normal wear. Its not a hard job if your a mechanically inclined. Few small tools, feeler gauge and new gasket for the valve cover. maybe a 30-40 min job .....many youtube videos.

After been in storage for two years I've tried using my Poulan, I clean the floater area making sure not old fuel is there, but still is not running unless I put gas directly into the carb and it does it...


The carbs on small engines have numerous jets which clog very easily. If you are able, remove the carb and soak it in a carburetor cleaning solvent......make sure to remove the gaskets or purchase a gasket kit before you soak. Remove the carb from the cleaner and let it dry. Reinstall.
You may want to check the fuel lines and primer bulb while you are at it. Good luck and I hope this helps.

I Have a push lawm mower (mtd product model # 11a-439s729) serial# 1d261k81143 I have to prime before pulling the lanyard to start . I have no problem starting the engine ,the real problem is it will die...


I really need your engine number but I am going to guess that it is a 3.5 to 4 HP Briggs & Stratton with a black primer bulb on the side of the carb.

Try this the next start. Take a screw driver handle just a bit smaller than the primer bulb and FORCE it against the carb body trying to make a seal with the primer rubber against the carb body. You use your thumb if you can manage to depress the entire area of the center of the primer bulb agains the carb body. If it runs normally when you do this..... the Primer Bulb has a pin hole in it. (No joy..... read on)

If after doing the above you strill have the same problem remove the air cleaner and tighten all of the screws that mount the carb to the gas tank. Often over time the carb body will warp and then it starts getting air introduced into the diaphram that is between the cab and the gas tank. Tighten the screws. There are usually 5 of them. (Remember the body is plastic.... tight but don't break it) Then try another start.

If that does not work the diaphram between the carb and gas tank is probably damaged and will need replaced.

If you need parts info respond with your engine number or go to www.briggsandstratton.com and look it up for yourself using your ENGINE TYPE MODEL SERIES number found on the air shroud above the spark plug.

Thanks for choosing FixYa.

I have a 4 hp Briggs and Stratton engine - stops running with gas


01 Sounds like you are describing the primer as being on the front of the carburetor air filter body. The line you describe is probably used to force air from the primer into the carburetor or into the fuel tank (a box of metal about 6" long by 3" wide by 3" deep?) on which the carburetor body mounts, from your description.
02 The engine will shut down with a little bit of fuel in the bottom of that tank. You should be able to remove the fuel cap, located on the top of the tank, just to the left of the carb and see into the tank. The carb does draw fuel from this tank as it runs.
03 How long does it run before quitting? If it runs ok and you get a small yard done and the engine does not emit black smoke, that might be normal.

Your engine model # 128602 Type 0212-E1. Forget about ordering from Sears and paying shipping and waiting a week. Go to your local Briggs and Stratton dealer (most shops are) and buy part # 694395. Should cost about $3.00

Can't keep mower running without consistently pushing the primer.


It sounds like there is water in the gas. The only way to remedy this is to take the carb off of the gas tank and replace the diaphragm, there is a small reservoir between the tank and carb...clean with WD-40 to remove water

Mower won't stay running


carb is gummed up. carb cleaner is the only thing that will help, Get it at walmart, spray can usually less than $3. Comes with a wand (straw) for spraying in small holes etc. Take the air filter off and look for small holes around inside the carb intake, stick the straw right in those and shoot, WEAR goggles or classes and rubber gloves, stuff is nasty. If it still won't run you will need to do some disassemble of the carb, if it has a bowl remove it and wash everything out with the cleaner.DO NOT however get the carb cleaner on the bowls top rubber ring it will wreck it. Be careful to put the float and needle and seat back as they were. The brass screw that holds the bowl on has some tiny cross holes in it, one strand from a wire brush works great for cleaning them out. Good Luck, Chuck
