First, I skimmed through all the posts. Solomon, when cleaning a carb, I know you've said its perfectly rebuilt several times, but one of the earlier posters was onto something when he told you to run a wire through the main jet on the main brass piece that goes in the bottom of the carb, sometimes soaking wont do enough, you have to physically remove the gunk.
I see your posted you have a brass piece in the front of the carb covered by a white cap that keeps coming out? It goes in all the way snug, not too tight, and yeah, your engine can run poorly or not idle right if its not clean too! Thats your idle restrictor screw, this has no adjustment, a good deal of these Tecumseh carbs had no adjustments for air fuel mixture, dont try to jet that out, it'll just make the engine run worse, and no they arnt interchangeable from different hps. Dont put the wrong carb on your engine, thats not the solution either, just see that both your brass pieces are in completely clean to where you can shoot carb cleaner in a can through them and they come out all sides. Nearly all smaller Tecumseh engines have this screw, get used to seeing it on your kart and bike engines!
Yeah, lean or rich those mufflers can do strange things, also if a single baffle is collapsed it can do strange things, or if you put a smaller muffler on it it'll act off or run even worse as he said before.
If you engine is backfiring period check the flywheel key and see that its in tact and not damaged (really sorry if someone said this first)
I'm super shocked your engine has points and condensers and looks the way it does, this almost seems unreal, can you please take some pictures so I know its really not electronic?
Briggstwin - if you mean all carbs have some form of adjustment I hope you mean idle speed... a ton of these Tecumseh engines that are on karts, pressure washers, generators, etc only have that.
Linksep - maybe not a "frankencarb", I kinda think thats what it had to begin with and its just not clean. What do you consider rebuilding? I see bad o-rings, gaskets, floats, float bowls, pick up tubes, screens, needles, seats, etc all week long.
I'll ask Robert at the shop tomorrow what his solution to this is because he knows a great deal more than I do about engines. (experience is the key)
