Is the source of the pop from the muffler or the carburetor? What are the engine ID numbers? Fixed jet or adjustable jet carburetor? New or old spark plug? Fresh or old fuel?

The poping is from the muffler.

The carburetor is adjustable ID# 1074 J2V.
Old spark plug.It looks good to me
Fresh fuel.

Although it appears OK, replace the spark plug, Champion RJ17LM or equivalent. I'd say you may still have a carburetor issue. How, exactly did you recondition the carb? Whatever cleaner you used? The exact parts used? Compressed air or not?

I used Berryman's B-12 Chemtool dip not spray. As for the exact parts# i toast the package but it was a full tecumseh carburetor kit. I told the dialer the Engine ID numbers and he gave me the kit to fit the engine (he said). No Compressed air water their all ports on carburetor and lit it dry all day? I'm going out of town for 1 or 2 days i will get a spark plug and see if it works. I will let you no.

Thanks PUEY61

Check your valve clearance, it sounds like the exhaust valve is not seating properly.

Tec. HM 100 Int. .08 Exh. .08

Check with the engine cold and the piston at TDC.

OK
I worked on it all day new spark plug no deference. After i bought the generator i pulled the tank off and put decal in it to clean it out and a new fuel filter. Today i pulled the carb bake off and it had dirt and gum in it. so looks as if the decal die not work. So wait is the BEST WAY TO CLEAN THE TANK? I need to fix this first. I'm going to buy new fuel lines and a new fuel filter after i get the tank clean. I have the carb in B-12 dip now cleaning.

Thanks for they reply (mikesmalleng)

Mike appears to have had a typo...The correct, valve clearances, if needed, would be .008" not .08" and actually the Tecumseh manual states .004-.010" on both valves but .008" is well acceptable. Let us know once you have done a complete fuel system service and then tried the running of the engine.

If it keeps doing it try closing up the hi-speed jet a bit.

I cleaned the tank looks like a new one inside. Cleaned the carb all ports look new. New fuel lines & fuel filter & spark plug. Now it will not run smooth at all. Adjustment screw want do nothing it runs to rough to adjust. It will run so so for 4 or 5 sec then bake to rough for 4 or 5 min some times stopping. You have to choke it to start it hot or cold. It run beater when i first started this post (i'm just not good at this). Now i no why i only gave $5.00 for it. I can work on ATV's so ok this is the same. NO not at all the same (not to me).

So please some one help a dummy

Thanks for they reply (kbalona)

Get something to catch the fuel and start by removing the bowl and see if fuel is running freely into the bowl. If the fuel gets there ok check the nut that held the bowl on, it has feed holes that get gunk in them which can be very difficult to remove(when you blow the holes the gunk just moves out of sight but is still there). If you have done all the soaking and cleaning(you have used high pressure air to blow out the carb). Check to see ig it runs while you feed the carb with gas(start a siphone from a bottle) if it runs ok get a different carb, if it doesn't it probably isn't a fuel problem. Have a nice day. Geo

Puey61: My mistake. it is .008 up to 5hp

But lets make this more clear for HUBBA,

.10 INT & Ex for L head

.004 Int & Ex for OHV

Since the popping is from the exhaust, I'd buy an in-line spark tester and check for sufficient spark from the ignition system. Briggs has a good, cheap one, part number 19368, that will clarify the condition of the ignition. This won't, however, tell you if the ignition timing is correct (in other words, a sheared flywheel key). If the ignition seems sufficient and you know the key is not sheared then you need to remove the valve cover (behind the carburetor) and check the valve clearances.
