Porta heat 55 model 50137 does not work, fuel problems

hi Herb.
there is a lot of places you could get one from.but i think it best you go to this link and see what helps you best.
i have had a look on ebay and there is some on there.
fuel filter for porta heat 100 Google Search

It could be many things.
When the engine crank but won't start
Retrieve PCM faulty code if any.
Engine need 3 things (Fuel, Air, Fire (spark)
1- Fuel = fuel pump working during the problem you can hear a sound at the fuel tank cap (remove)
All Fuel Injectors working.(Power and the spray).
2- Air = MAF defect (Mass Air Flow) no code will be set
When the engine is running with a screwdriver lightly hit the MAF the engine will stall if it's the problem.
air filter restrictions
3- Fire= Is there spark at all spark plugs wire?

Find out the ground of power windows it could be the same as fuel pump or ignition system (Ground corrosion, high resistor)
and many more.
See good technicians to fix your car..

Hope it helps

Follow gas line from tank to carb. Observe bottom of carb. Remove screw holding carb bowl to carb. Clean bowl. Pinch off gas line with pliers. Ensure float falls down easily. Float up no fuel flow, float down fuel flow. Observe screw that hold carb bowl to carb, see if it has a whole thru it, clean with small wire, bread wrapper works good. Observe center fuel port, clean with wire. Remove pin that holds float and meter needle, clean port with wire. Reassemble. Ensure air filter is clean, oil is full, 30w oil, spark plug is clean and properly gapped. Replace air filter and spark plug once a year. Empty old oil out if any grey is observed in oil, this is moisture, can accumulate after winter storage. Clean out side of carb with carb cleaner to ensure choke can rotate freely. Always use Stabile in gas.
All newer mowers have a low oil shutoff.

Suggest start w/ the basics : Air, Fuel, & Spark. Internet search indicates that it's a Briggs & Stratton engine, which I just worked on yesterday (165 cc version). Easiest things first - ensure that there is FRESH fuel in the tank. If it's been sitting there all year, drain it out and refill with new fuel. (make sure you follow mfgr's recommended fuel type.) If you have a primer pump, make sure you can hear fuel flowing when you depress it (typically 3 - 6 pushes to prime the engine). If not, then youi may have a fuel line or fuel filter clogged. If you remove cowling/covering over top of engin, you can get access to the air cleaner. Remove the air cleaner/filter, and you can see into the carbuerator. This should make it easy to see if the primer pump is squirting fuel when depressed. While the air filter is out, make sure it is clean. If gunked up, I usually soak it and wring it out in fresh fuel, then let it air dry to clean it out (mine is made of foam). If it's a cartridge type air filter, blow it out w/ compressed air, or put a new one in if it's dirty. Lastly, if you have an assistant, you can check to see if you're getting a spark. Remove the spark plug, inspect if for correct gap and overall condition - remedy if you see something wrong. Then with it out, connect the spark plug cable (the high voltage line) to the top of the plug. Now, while touching the threaded part of the spark plug to a bare metal part of the engine case or lawnmower chassis, have your helper pull the starter cord and look at the plug's gap for a series of sparks.

If you don't see any sparks jumping the spark plug gap, you may have a bad plug, bad cable, too big a gap, or a bad magneto, or corroded connection to the top of the plug.

If you don't have fuel flow, you may have a clogged fuel line or fuel filter.

Air flow is pretty basic, so with the air cleaner removed, it should be pretty obvious if you have an airflow restriction. You can leave off the air cleaner/filter to troubleshoot the engine and to start it, just don't operate the mower without it, or you risk sucking in junk, rocks, you name it, into your engine.

THis may go without saying, but also inspect all linkages, springs, cables, etc. IF you see something loose or broken, check the owners manual or diagrams and remedy that. Also check out the Troubleshooting section in the owner's maual (available on-line at Husqvarna)

My problem yesterday was very simply BAD, OLD GAS. Briggs & Stratton make a pretty reliable, easy to start lawnmower engine. But even that's not enough if you're feeding it bad or contaminated gas.

One question: have you tried the machine without the porta-filter attached? If it works through an entire cycle without the porta-filter attached, then the porta-filter is clogged. I've lost that special little tool to poke into the hole on the porta-filter, but a fine-tipped needle works just as well. Other pins that I've tried are too thick. Sometimes there's a piece of coffee that has made it through the top part of the filter gets stuck at the single hole that is the exit. Find an appropriate pin and poke around with it, then run WATER only through the filter. If it makes it through a cycle, you've fixed it. This clogging can happen very frequently with too finely ground coffee.

If however, your machine stops and beeps without a filter attached, then there's something restricting the flow inside the machine and your only alternative is vinegar, or similar decalcifier.

Good luck!

Some possible solutions (from general experience (i'm 55 yrs old)): 1. Plugged up fuel filter; Replace it. Part costs less than $10.00.If the filter is just in front of the tank, it should take a screwdriver and 15 minutes or less to swap. 2. Water in the fuel tank; Add a bottle of "Heat" to the tank. Cost ~ $3.50 or less. This next may require some trouble shooting or head scratching first. DO #1 & #2 First. (Won't hurt & Doesn't cost much) 3a. Partly clogged fuel line. 3b. Cracked fuel line. (Sucks air into the fuel line) Depends where the fuel pump is.(Also look for fuel leaks, especially around hoses in the fuel line.) 3c. Clogged carb.Filter (if it exists). Verify fuel delivered to Carb by disconnect @ Carb. attach small hose to catch container then turn on (NOT Start) ignition.Should hav a steady flow of fuel for at least several seconds. If so, Replace carb. filter. 4. Weak/ failing fuel pump. Major pain but backyard mech can do it with helpmay take half a day.May need to have a few empty gas cans available to save the existing fuel.. Replacement In-Tank pump assembly should be less than $50.00.

Not in any way,It can only reduce air flow to the inside of the vehicle causing the a/c and heat flow out of the vent to be deminished

Hi, I see you have changed a bunch of items, but do we know if the engine is getting fuel pressure? (55 psi at test port), or getting good spark? Could the spark plugs be fouled?I think before you replace too many items, you should start with basics. Good luck, Thanks...

Since you don't indicate the make and model, I can't give you specifics, but when I had this problem it turned out to be a dirty carb. This can cause uneven fuel flow and loss of power. At full throttle, you may not be getting sufficient fuel to work properly. Try cleaning the carb a nd update this with the results.

Hi ..... Go through the above list, pay particular attention to fuel delivery ie blocked breather in tank, any filter fitted to tap or change in line filter if fitted. Easy to check, take off fuel delivery to carb (place container to catch fuel), start bike and fuel should come out a strong contant flow.
Let us know how you get on.
