Also the manual for the engine says all fuel oxygenators are fine (ethanol, MTBE, methanol). I can accept the fact that maybe this unit has dud carb, but are we really sure it's not something else? Also, I've used snowblowers for 30 years, I doubt I'm just now noticing the glowing muffler. I get tired of just throwing parts at things when there should be actual trouble shooting based on symptoms. Is the glowing muffler due to a rich or a lean mixture? Until that is cleared up, I'm really not comfortable throwing money at a carb
BTW, my neighbor has yardman with the same engine, and that one does not glow, but maybe his is messed up too? Anyone else with this specific engine please chime in, the newer ones sound a bit flakey compared to my past experience with snowking engines.

As far as when it hunts, it certainly does it at high idle, as far as under load, I will have to wait until we get more snow, so not sure. I will also do the float pressure check and make sure it seating, as its still leaking form the bowl. I am also going to check the intake and carb gaskets seal integrity using starting fluid, or did i read someone used WD-40 for this? Will also check the timing and flywheel key as some have suggested.
will post back when I get it fixed.
PS- is it really hard on the engine to run it with the glowing muffler? Am I in danger of burning a valve or something?
