SOURCE: LTH1536 engine surges

We had some issues in the UK like this, it was a fuel issue, there is very little gravity feed from the tank to the carb, we were fittind an electric fuel pump which cured the problem, might be worth checking out.

Briggs & Stratton 44N877-0005G1. Lawn tractor runs 10 to 30 minutes then engine starts cycling and dies. Takes 1/2 to 3 hours to re-start


be sure the air vents are clean and not clogged up with dirt, oil or grass. sometimes when engines are dirty they will tend to over heat and cause the fuel to boil. be sure the fuel lines are away from the engine. might change the spark plug. they tend to break down at high temperatures. last you may change the coil.

Check motor mounts and transmission mount

Also check the air tube (TOP AND BOTTOM) for hairline crack.

A worn motor mount can cause excessive vibration and damage the air inlet tube.

Use a bottle of yellow HEET dry gas / fuel dryer to remove moisture in your fuel tank.

What should I do with my husqvarna 130BT because I put in too much oil with the gas and it won't start?


First, you need to dump all of the fuel out of the gas tank, Preferrably into a gas container. If you know how much oil you dumped in, you can calculate how much more gas to add. You could also just dump the gas, re-mix some new gas and oil, whichever you prefer.

If you are comfortable doing this, remove the fuel lines going to the carberator and let them drain into a pan. Pump the fuel primer to purge the gas out of the carburator, and then re-install the fuel lines. This might help you get it started a little faster, but its not necessary. You can burn the old gas in the engine at it will be fine.

Next, remove and replace the spark plug. Its probably fowled out with too much oil. Keep a can of carb cleaner and a small wire brush handy, you may need to clean the spark plug a couple times. If it gets too dirty, you can replace the spark plug with a new one. Do not burn Carb Cleaner in your engine for long periods of time, it will damage the engine.

After you have installed the spark plug and put some correctly mixed gas in the tank, Try to start the engine again. There will be some residual fuel in the fuel lines going to the carberator, so you will need to burn off that gas.

If you can't get it to start, try these steps:
Choke off, throttle wide open, crank several times. (or let it sit in the sun for a couple hours) (this corrects flooding)
Prime carberatur, Choke full on, throddle idle position, crank until it fires once but does not start.
Choke half, crank until it fires again or starts.
If it starts skip this step: (Choke off, crank until it starts).
Keep the choke on half for about 10 seconds and let it idle.
Put the choke off and let the engine warm up for a couple minutes.
After warmup, test the throttle to see if it will run at full throttle (it may take some fluttering until the engine is fully warmed up)

Let the engine run at full throttle for a few minutes. The exhaust may be a little more blue-smokey than normal...this is the excess oil burning...totally normal and harmless.

After about 30 minutes engine will start surging, by partly pulling the choke out it will run better. The carb has been recently rebuilt as well as new filter and fuel line to carb. Tried different fuel...


Typically a surge is caused by a lean condition. I'd say the float is set to low and this is causing the engine to lean out & when you apply the choke it richens it back up.and the surge stops.

My lawn mower is surging and spark plug is black is this lack of air briggs& stratton . plus runs ok when running out of petrol /????


Are you running it with the choke on? Also if the air filter is dirty it will do that as well. Black plugs means it's getting too much gas and is not getting the proper air to burn properly. Some engines if you rev them up with the handle right as fast as it will go automatically the choke is on.

What are the steps to start my husqvarna 125b handheld gas blower


Put fresh gas/oil mix (if it is a 2 cycle) in the tank.

Put the choke on. Push the primer bulb 3-6 times. Pull the cord until the engine sputters. Put the chock to 1/2 way, pull cord again. Should start and run a bit with choke set there, then in about 10 seconds, put the choke completely off.

Engine surging


watch the governor and see if its stable or if it's the cause of surging and then it can be determined why the governor is adjusting the RPM. Hold the governor still and see if the engine surges then too.

THIS IS CAUSED BY A PIECE OF DIRT STUCK IN AN AIR BLEED JET OF THE CARB OR THE CHOKE BLADE NOT BEING FULLY OPEN, CHECK THE CHOKE BUTTERFLY 1ST, IF IT IS OPEN ALL THE WAY THEN REMOVE AND CLEAN/REBUILD THE CARBURETOR
