It starts fine and runs on choke but not off choke

It cranks immediately; new gas, full oil. warms up nicely on choke, but the minute we take it off choke, it starts to sputter and dies. Every time.

It sounds like you are not getting enough gas. I think it's the diaphragm, When you take it off of the choke diaphragm controls the gas flow, apparently yours is just shutting down. It's very inexpensive, and very easy to replace. Good Luck :)

Hi, I have a 13.5hp Briggs & Stratton motor which starts and will only run on choke slow rpms and mild smoke.


check the point where the fuel hose goes to the fuel tank
there is very fine filter in the hose that could be blocked preventing full fuel flow
only running on choke indicates insufficient fuel flow

My lawn trimmer stalls out after running for several minutes


id Check the spark plug. If the electrode on the plug is worn , id replace the plug. Make sure you check the gap on the plug before, you install it. Id also check to see if the air cleaner is dirty, or not. If the air cleaner is dirty the engine can't breath. Is the gas old that's in the trimmer? If it is dump it out, an replace it with new gas/oil. Are you sure that you mixed the gas/oil correctly? Is there a choke button on the trimmer? Make sure that after you start the trimmer,an it warm's up a little you shut the choke back off.

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.

unleaded fuel is notorious for going stale,and it can leave a resinous coating in the carb-try running the saw on half choke with new gas and less oil eg 50 to 1 for say ten minutes,this should clear the gunk out-if this does not work,you have two choices-strip and clean the carb,or adjust the H (high) scew on the carb anti-clockwise by a quarter turn a time till it revs out full bore-good idea to remove the chain and wear ear defenders when adjusting-and always use a chainsaw at its max rpm,or you run the risk of "kickback"

Hard to start lawn tractor


I have 2009 lawn tractor that will not start (from day 1) unless I use a small squirt
of start fluid into the air cleaner area. Nothing else seems to work. The battery will run down before it starts. Once engine is warm it starts great. Love the tractor,
hate the starting problem. Elevation is not a problem in michigan.

13.5 OHV B&S won't stay running, blows gas out carb.


Check to see if the oil is over filled. check if the oil smells like gas, could be a gas leak into the crank case.
More than likely the head gasket is blown internally, causing excessive crank case pressure
