charger 10 carb issues

[Gregor 4,847]

Even though, if the timing were off some, I would expect a pop, sputter, something.

I agree Gregor.      Unless it is only firing on the  exhaust stroke where there would be no fuel in the chamber.

With good spark and, good compression, if fuel is sprayed into the intake,  It should run or try to run without a carb.

 

Check to see if the points open when the piston is at  TDC on the power stroke(both valves closed).

Electronic ignition isn't it?

Good point Eric.   If it was converted....could be the problem.

at times it tries to start but for only a minute as smoke does come out of the muffler but that is all

nothing has been changed it seems the electronic ignition is from the factory ;all I  know is it came that way when I bought it about 5 years ago for 200

yep I agree but I feel if I keep on trying to fire it up it will damage the ignition system  as years ago I had another horse with the same set up and after time it fried and it was very hard to replace

well if there are points on this motor they are well hidden as I sure can't find them besides being a electronic ignition set up there are no need for points or am I wrong here 

[Ed Kennell 41,938]

No points if it is solid state ignition.

so very true ;I have been told it might need to be timed but really I have no idea as to how to do this

I'm thinking your carb is fine. 

 

Other issues.....

 

I agree as even a brand new one should at least fire it up and run ;I was told it might need to be timed but really I haven't a clue as to how to do it ;thanks so much for your input

Pages 45 - 47 in the posted manual refer to the timing and ignition on this motor. Personally I have never dealt with timing on a 10 HP Tecumseh.

 

I will add though, until you can at least get a wet spark plug, I would continue looking for a fuel issue. All the spark in the world won't do you any good, without fuel.

One  more thought. I want to say first, I AM NOT A BIG FAN OF STARTING FLUID! But desperate times call for desperate measures. Open the choke and throttle, give it a healthy dose of starting fluid. If it does not pop, sputter, spit, backfire, or blow up, it's time to look beyond the fuel issue.

thanks so much for the in put 'this will be my first time with timing a motor

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

according to the spark plug tester I have all kinds of spark plus even with a new one; I should mention that I did remove the head and both valves are working as they should but it seems in the past that one owner  might had issues with the motor as there were 2 head gaskets which is really odd but that shouldn't make any difference in the starting issue ;I bought this old girl about 5 years ago and never any issues till the tranny started to leak so a mechanic that I knew removed the tranny and replaced the seals and once there he changed the gasket on the fuel pump and the carb plus he tweaked the carb as he thought it needed it but after wards it ran so fine till this issue happened ; I can not contact him any longer as he passed away a few weeks back due to this virus ; the thing is even with a brand new carb and I never touched any adjustments plus had the other one rebuilt ;I should be able to get the engine to run ;not un less the current repair shop didn't rebuilt it but just a once over but again with 2 carbs it should at least start'

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?

 

no it does not

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

yes I do

I have downloaded the document about a 10 horse and all of the settings and more but it really doesn't say any thing  about timing and with you I have never timed on either;

and yes I can crank this all day and run the battery dead hoping it would  at least fire up and yes with out fuel we can get spark but with out both it will never start ' it seems the fuel bowel is full

Is it possible the tester is faulty?     Have you actually checked for spark at the plug?

If you have a good spark at the plug, good fuel sprayed into the intake with the choke and throttle open, good compression, and it still does not attempt to start,  I give up.

I don't know if this applies to 4 strokes, but I work on a lot of 2 stroke motors. I can't tell you how many times I have had spark to the plug, but not through the plug. Even a brand new one.

oh for sure I have good spark as my hand touched the coil wire and I got snapped good 'in time I will figure it out

Touching the coil wire tells you there's electricity THERE. 

 

It does not tell you there is reliable spark AT THE PLUG INSIDE THE ENGINE.

that is so true ;I did get a new plug today and again removed the head it seems someone in the past added another head gasket which makes 2 on it ;where one is only needed 'so turning the fly wheel by hand the piston came up as it should plus both valves opened and closed ;I did remove the carbon that was built up on them plus the top of the piston ;then after putting every thing back together plus priming the carb as I tried to start it still nothing ;the plug was dry where there should had been a smell of gas or even felt wet ;as I was turning it over there is a strange noise at first I thought it was the starter but it seems more like inside 'so I gave up ; some members mention that it should be timed but really I don't have a clue as how to do that ;so yes with a brand new carb and the other being rebuilt there is a bigger issue but what and where '
