snowblower wont start unless gas is poured directly into carb

i have a very old hahn eclipse snowblower im fixing and it was having starting issues and i noticed that the engine doesnt pull fuel from the tank into it so i had to pour gas past the fuel filter down the gasline then it started and ran off the fuel in the carb then died i did this several times but it never pulled fuel from the tank. is it the fuel filter?

It could be the fuel filter or a blockage somewhere else like in the fuel tank. If you have a fuel shut off valve I would confirm that it is in the open position.

My general rule of thumb when refirbishing old equipment like a snowblower, is to replace the fuel lines, fuel filter, spark plug, oil, and pending condition, replace the belt(s).
This way here, you have all the potential trouble makers replaced and good for many years to come. Fuel lines are pretty cheap, and not a lot is needed on a snowblower (probably 2ft max).

When I did my old snowblower, I also greased all bearings and grease nipples, and inspected/tightened (as needed), all cables and cotter pins.

i pulled the side of the fuel filter facing the engine out anf fuel spilled out of it conferming that the fuel line isnt clogged but when i hooked it back up fuel didnt flow to the engine i think. also all the controlles are messed up because i had it running with gas in the carb for a little and i shifted into forward then nutral but it didnt stop also i pressed the blade button and after i let go the blades kept spinning and it still was going forward o and it wint run unless choke it all the way up

Sounds like you have a bit of work to do.
I would start by adjusting the carb. Sounds like the carb is set way too lean to run. When you adjust the carb during the warm weather, adjust it a bit to the rich side (just a hair). If you tune it perfectly in warm weather, you'll be choking it during the winter in the cold air.
I made this mistake. Tuned perfectly during the summer when I did the work, ran like junk when it came time to using it until I re-tuned it.

{{hahn eclipse )) This unit must be very old,, Punch the engine #'s in here & We'll get you dialed in,,,, Chances are you will have to re & re the carb to rebuild it if it's not drawing fuel,,, Roger

keystart,
most cases, there are two screws, an idle screw and a A/F adjustment screw. I believe mine at the A/F screw in the bottom of the carb, through the center of the float bowl.
I do not remember the exact specifics for mine, but I think it was finger tighten the A/F screw, then back out a 1 and a quarter turns.

Based on what you have posted, I would probably suggest removing the carb, cleaning it up or replacing it, and install with a new gasket. You can generally buy pre-cut gaskets or as I did, trace the carb out on a sheet of gasket material and cut my own.

I tried the numbers in several sites including Briggs & No Parts Found,Verify the #'s & if it's as old as the series you gave us ((1942??)) You may have to search for some speciality sites.. Can you post pics of the carb?? I wonder if its just an old flow, or pulsa jet type?? Roger
