nEW cARB IS SURGING, HOW TO ADJUST?
For model number 31AH64FG731
Hello Paul,
Thank you for writing in. Here is some information we have found: Confirm It’s a Fuel Delivery Issue
Before adjusting anything, check:
? Fresh fuel (old fuel causes varnish and lean surging)
? Fuel filter not clogged
? Fuel line not cracked or collapsing
? Tank vent not blocked (loosen cap briefly to test)
If it still surges, move to carb adjustment/cleaning.
Clean the Carburetor (Most Common Fix)
Surging is often caused by:
Partially clogged main jet
Dirty pilot jet
Varnish buildup
Basic cleaning steps:
Shut off fuel.
Remove carburetor bowl.
Remove main jet (usually in center of bowl).
Spray carb cleaner through:
Main jet
Emulsion tube
Pilot jet
All visible passages
Blow compressed air through passages.
Reassemble and test.
?? Do not poke jets with wire — you can enlarge them and ruin fuel calibration.
We hope this helps.

With WD-40 or equivalent, spray the four nuts on the underside of the snow blower housing that hold the shave plate to the housing. Also spray the two bolts that hold the shave plate to the side of the housing. Let sit for a few minutes and using a 1/2" box end wrench remove the four nuts on the bottom of the housing. If necessary, app

It is recommended that the bottom bolts and nuts be replaced with 5/16-18 X 3/4" long zinc plated carriage bolts using zinc plated washers and ny-lock nuts. It is also recommended that all of th screw threads be coated with an anti- seize lubricant so disassembly at a later date will be easy.
I ordered a replacement chute rotation gearbox. The small metal ball on the end of the cable (on the replacement part) was attached about 1/8" too long and made it so that there was too much play in the trigger that operates it. Thus, the replacement part did not work. I called customer service for directions about returning the part.
... Read more They said it must have been defective. I'm still waiting for instructions about returning it for a refund. The whole thing was a bust. I ended up disassembling the old gearbox and fixing it, instead of replacing it (which would have been my preference). The replacement part did not work at all!
