    Probably yes, you have created more damage than will be cost effective to repair. To check, remove the muffler and look into the cylinder with a flashlight. If you see scratches on the piston and/or the cylinder walls, then the piston and cylinder will have to be replaced. This is not an easy job. Most shops will charge $40 - $60 in labor. The parts will probably be another $60 - $80. Probably cheaper to replace the blower.

You need to empty the gas tank, then you need to install a new spark plug.

You might also need to clean the air filter depending on how long you ran the unit.

Next refill with the correct gas mixture, and after a few tries it should start!

I put it 30 dollars of unleaded91 that was given to me from my mum an heard it was mixed with a bit of diesel gas put it into my 2005 Mazda premacy went down the road and the car started shaking an started...

The gas/diesel was in a can from your Mum or you bought the gas/diesel at a gas station ?
The station needs to be responsible if you bought a gas/diesel mix from them.
You will have to have it towed to a mechanic. The lines and tank will have to be emptied of diesel and flushed out. The plugs will need to be changed and it could have ruined your catalytic convertor.
My daughter did a similar thing to her car.
Bad news - it can be a very expensive fix if the cat. convertor is ruined.

Son put gas with oil, if i drain it will that fix it or is the fix more detailes it will start but blows out gray smoke

You can drain it and it will be just fine. Putting mix gas into an egine that just needs gas is fine. Its going to smoke untill all the oil is burnt up. He didnt hurt a thing. Altho if you put just gas into an engine that need mix you will cause alot of problems so becarefull with that. Good luck and if you have any more questions about it feel free to email me.

My son accidentally put straight gas in our gas weed wacker, now it won't start. drained gas and replaced with correct mix, still no go.

Try taking the spark plug out and spraying a little WD-40 in the hole and letting it set for a time. Then pull the cord slowly one time and then replace the spark plug and try to start.

Have less than an hour on it since new and can't keep it running. Starts hard. Have tried every trick that I have read about on the online chats and am convinced that this machine is a P.O.S. Anything...

You may have tried this but fresh gas. If it only had an hour on it but it sat around for 6 months or a year, the gas may have gunked up. But you probably already knew that. If it is gunked up try putting a bit of straight gumout or the like (not the spray but the carb. cleaner you mix with gas. and let it sit a few hours or over night the try and start it with a full tank of fresh gas mixed with the proper amount of oil. NOTE: there does exist some possibility that this may ruin the carb so you may want to start with just a small amount of gumout mixed in W/ gas. but since it sounds like you are about ready to through this out . . .

Does the poulan p4tn20sa take a gas/oil mix?

I cannot find any literature on your mower, but I'm guessing it has a 4 stroke Brigg's engine on it. If so, then there is no gas/oil mix requirement. The only engine's where you mix gas and oil are 2 stroke engines, which are not installed on most of today's mowers. There should be a separate place on your mower to put gas and oil in. If so, then you should probably run straight 30 weight oil in it and do not overfill it or you'll ruin your engine. I hope this helps. James.

Need to now how much oil and gas to mix

Most newer 2 cycle motors use a 50to1 mix. Older models use 40 to one. If you don't know the exact mix a 40 to one ratio will work for both types.
The really old machines (30 years old use 32 to 1) and I suggest using Amzoil Synthetic 2 cycle mix. It will works for all mixes and not ruin your motor if the mix is too light.

Saw wont start

Think about joining the Army and tell your dad. This will take your dad mind off the saw while he is trying to change your mind to stay in school.

Actually 32:1 mix is richer than 50:1 meaning it shouldn't overheat the saw piston.

Is the gas fresh? Is the mix actually correct? It very hard to see a spark from a two cycle engine. You also need to pull the starting rope very fast for it to operate.

My guess the plug is fouled out it needs to be clean again or replace.

Used wrong gas can and ran saw on pure gasoline.

if your saw didnt lock up ,or overheat it should run again, take out spark plug, with switch off, put your thumb over the hole and check for compression when you pull the cord. if it pops your finger off the hole you probably didnt cook the rings, or burnt the piston, the raw gas may have washed the cylinder down enough to temporarily lose compression (lack of oil seal). refill tank with proper gas/oil mix, squirt a small amount of oil in cylinder and pull it thru a few times , this should seal up the rings again , put in a new sparkplug, and try normal cold start, you may have to clean the plug a couple times before it runs. if it runs but lacks power my guess is the rings got to hot and lost their temper or scored the cylinder. dont use alcohol blended gas this will ruin fuel lines , they soften up and fall apart etc. premium regular if you can get it, check the fuel line to be safe for pinholes as they will **** air and not start if you get alcohol blended gas. anyway good luck. geo_1
