Jiffy Ice auger tuneup

I rebuilt carburator on my 2 horse jiffy. I had it set so it was running mint, but my younger brotherhas been using it for a while and was playing with the screws. I talked to a small engine guy about a month ago and he told me how far the screws are turned out from factory, but now i can’t recall it(should have written it down )

The top screw is just an adjustment for the throttle, but then below that one to the left(closest to the engine), and then another to the right of that one. Roughly, how far out should each screw be turned out?

Thanks

(SRY, I know explanation is bad, but if u know the carb, u should understand)

The 2hp and 3hp Tecumseh engine for the Jiffy’s usually use the same “base” settings for the set screws. Turn them clockwise gently to seat them both. Gently is the key, as you don’t want to ruin the seat. Turn the right one (farthest from the engine) 3/4s turn counter clockwise. This is the one for fast speed. Turn the left one (the one closest to the engine) 1 full turn counter clockwise. The engine should start and run now. The right one is for full throttle speed, and can only be adjusted under load. If it bogs down while cutting, let up on the throttle, turn 1/8 turn counterclockwise, then retry. Do the same thing with the left one at idle speeds when the engine is warm. Turn a very little at a time until the engine “sounds” to be idling optimally. This should help you get her running nicely.

i brought this up last weeka dn am going up to get some sea foam tonight and thinking a new spark plus since havent changed it for like 4 years for my 3 hp model 30…..cleaned the carb last year but still makes me have to choke it way to much!!! any tips and also what size spark plug does it take anyone know at work need to stop on my way home
