charger 10 carb issues

[upstateyankee50 59]

first of all I want to thank the ones that did reply and offer there thoughts as to why the carb is acting up; the thing is I can not get it to fire up ;the gas flow to the carb flows like a river so the pump is fine ;the inline filter was checked and it is clan as it is one of there glass types where you can see the fuel and it is clean ;taking out the spark plug it is dry where it at least should be wet from gas ;even trying to prime the carb it still will not fire up besides at times I can hear a snap might be from the starter but I am not sure so to be safe I walked away as not to end up with a bad motor ;the dealer where it was taken a week ago Tuesday told me he would check it out yesterday well around 3-O- clock yesterday my daughter and son went with me to check it out well the tractor was just sitting where it was taken off so we loaded it on the truck and off we went ;there is no reason to let it sit any longer and really not knowing when it will be looked at ;so it is here where it belongs ;the pitch of the loading ramps were at a 90 degree angle going up and no way could be push it that up that height so putting the forward control in forward as being an automatic I let the motor creep its way up the steep incline ;good things the batter was new ;not a word was spoken from the mechanic so again off we went so now I am trying to go alone here and figuring out where to go ;in the ears there are a few repair shops but due to the virus they have closed ;as far as setting the adjustments it would hard as it won't start to even get it warmed up 'so again any thought sure would be appreciated ;thanks everyone

Can you post some pics of the tractor, engine, and carb so we can see what we're up against?

 

I'm thinking you'll be in need of a carb rebuild to start.

I may have missed part of the story, but do you have a good spark at the plug?

I let the motor creep its way up the steep incline

I don't quite get this. Did the motor start?

 

Are we in fact dealing with a Tecumseh 10 HP?

 

I don't know if the HH100 has Automatic Compression Release or not, but did you check for any compression at all? Pull the plug, and hold your thumb over the hole while cranking. Any compression?

 

I guess that answers that.

 Like @Gregor said.

 

If you have fuel getting to the carburetor but your spark plug remains dry, then I would suspect either a clogged main jet, clogged emulsion tube, or no compression. No compression would mean that there is nothing to suck the fuel air mixture into the cylinder.

 

 

Things to check

1. Does the engine seem to turn over really easy? Turn the engine by hand, you should feel resistance as it reaches the compression stroke.

2. Remove the air cleaner and hold you hand over the carburetor while turning the engine over, you should feel suction at the carb.

3. Remove the spark plug & hold your finger over the hole while turning the engine over. You should feel pressure trying to blow your finger off from the hole.

 

If you find that you don't have compression, then it's time to pull the cylinder head off and see what happened. Hole in the piston, broken rod, or a valve stuck open.

Does it start or run with full choke? Does it run if you hand feed it? 

Might be something as simple as a stuck float/inlet valve. 

Do the compression test as outlined above and if it passes a good old fashioned carb cleaning is in order.

trying to prime the carb it still will not fire

If it does not ignite when you spray fuel into the carb,  You do not have spark or the intake valve is not opening.

i did have the carb rebuilt but I am not sure if the shop did put a new kit in to it; I did buy a brand new carb for it from a dealer here and he said it is the correct one for this motor ;well after installing that one the tractor still wouldn't start even when primed ;so that is when I decided to have a repair shop rebuild the one that came on the motor ; lME-29

yes it is a 10 horse Tecumseh motor and I do have spark plus compression ;odd that I always started up every time but when I wanted to mow the yard a few weeks back that is when I had issues as it wouldn't start even with priming it ;it wanted to start but that is all ;it has the electronic ignition and I was concerned if I tried to crank it so many time the ignition would had burnt out so I replaced the carb with a brand new one from a dealer and he told me it is the correct carb for this motor ;

thanks and I really never thought of a few things that you suggested ; the engine does turn over really easy I did remove the plug and tested for spark as I was turning it over I could fell the compression 'yes and my last thought was to remove the head off and check the valves ;I will let you know and for sure I do hope that I don't have a busted rod as odd it has always started great before this issue 

[ebinmaine 72,645]

It's important to keep in mind that you should never ever assume a new part is a working part. Every manufacturer in every industry all around the world has an acceptable defect level.

 

You say you've replaced the carburetor and that your dealer claims it's the correct one. Where was it made? How old is it? Is it gummed up? Is it ACTUALLY letting the gas go through it?

 

How are you testing for spark? Are you using an external spark plug tester that allows you to leave the spark plug in the engine as it should be?

no it will not start on full choke at times it seems it wants to start but won't ;even priming it rather hand feed still nothing ;I did have the carb rebuilt by a dealer but who knows if he really replaced any thing

yep that was my next thought the intake is stuck I am going to remove the hard today and check things out and hope it isn't a serious issue ;thanks for the imput

yes you are correct about assuming but I do go buy what the dealer says as far as being the correct carb for it  where was it made well there are no markings or numbers on the carb the new on that is 'it looks brand new with the instructions ;as far as your next question all I can tell is that the bowel gets full 'the tester is an external tester as leaving the plug in the engine I as well replaced the plug but that didn't help either ;thanks for the input and I will let everyone know once I pull the head and check the valves if they are opening and closing as they should ;

well again; I put the thumb over the plus hole and I had a lot of compression than putting my hand over the mouth of the carb it sucked my hand plus my hand was covered in gas ;then I removed the head and both valves are working properly as both going up and down as far as the emulsion it was clear as when blowing though the tube I can hear air through the carb; so it seems the repair shop really didn't rebuild the carb just a fast cleaning ;I did chat with the dealer who sold me the new one he says it is the correct carb for the 10 horse and there is no way he will give back the 103 plus for it ;if that carb was the correct one the engine should had started as I didn't mess with any adjustments nor on the one that came with the 10 horse ;so now to get a kit and try to fix it myself ;to all that replied with there thoughts and help I sure do appreciate it ;in the future once I get the old girl running I for sure will let you know again thanks so much guys ;

[ebinmaine 72,645]

Given that your hand is covered in gas the carb may not be the entire problem. 

That tells you it's at least getting into the bowl and up the tubes. 

 

 

Engine runs if you SPRAY gas in it?

I did the hand test over the spark plug hole and  had lots of pressure as well as placing my hand over the front of the carb and it sucked my hand in plus my hand was covered in gas ;than removing the head both valves are opening and shutting so it seems the repair shop just gave it a once over and really didn't rebuilt it with new parts ;lesson learned as not to trust anyone ;thanks for the input and I will let you know what happens

yes that is true and no it will not run even with a spray 

[Gregor 4,847]

Starting to look like a possible timing issue.
