Default New camshaft and now running crappy

Hi again...
I got the new cam in like I said and it was running awesome... Tuesday afternoon I changed the oil and I heard that hissing noise through the slit in the hose so I know I primed the pumped, drove it around and I was running good... Yesterday we got that snow (western NY) so I plowed my driveway twice, took about 1.5 hours each time.... then I had to go plow a friends so I loaded up the wheeler and took it to his house and plowed his drive way, his is much bigger so it took about 3 hours... I left the wheeler on the trailer last night and this morning I went and started it unloaded it and I started to plow my drive way and I about 25 min in it started starting running rough... not backfiring like before just bogging down.... I shut it off cleaned out my garage and when I started it again it ran fine for 5 min then started running rough again idles fine but no mid-top end power... I tried running it with the gas cap off but still ran crappy the tank was also about empty so I filled it with gas but still no luck... so now it is inside with a salamander plowing on it to thaw it out.... new sparkplug and wire when I did the camshaft... help again please

Since you ran it almost out of gas,possibly sucked some trash,water through the pump into the carb. First thing I'd do is pull the line going to the carb,crank the engine over and see if you have a steady flow of fuel. If you do then you may need to pull the carb and clean the jets.

okay I just got home and I went out and tried to start it, it has been at room temp this hole time... It started right up and idled fine I gave it gas and it revved up good, then same thing acting like it is starving for fuel. I took off the gas line at the fuel filter and it pours out steady... when I turn it over it sprays then nothing in sync with the motor turning over ( the spray is no more than when it is just gravity feeding out) and it does the same thing with the fuel filter on... I came in here to post and reread what you said and I went back out and noticed that there is another line that goes from the pump to the carb. I took the line back off at the fuel filter and hit the start button and the wheeler started up and ran with the line that has the fuel filter disconnected and dumping gas I revved it up and it ran fine... no bogging or anything... So my question is- which of the two lines should I pull to test the pump and does anything I said in here ring any bells?
thanks OPT Hope I made sense of what is going on...

okay now this aggravating I just went back out to make sure what I said was accurate and I started it up and it idled fine but ran crappy during mid-top end throttle but when I disconnected the fuel filter line it ran the same but stayed running... and I should not have said starving for fuel because I do not know the difference between starving for fuel or to much fuel...

Could be a fuel pump diaphragm is leaking allowing gas into the vacuum line to the carb. Pull it and see if you see gas residue on the hose or smell gas from the line.Top nipple on the fuel pump is the inlet from the fuel valve. The one below it (with the filter) goes to the left side of the carb(as you're sitting on it) The angled nipple is the vacuum line leading to the right side of the carb.

okay I am going to go out there right now to do that but just curious does that sound correct about the spray then nothing then spray than nothing when turning the motor over?

okay I just went out there and took the hose off at the pump and looked inside with a light and it is completely dry, I started it with out the hose on and it ran fine for about a min or 2 then just like before started running rough not wanting to go about mid throttle but when I force it to rev up it then it does not even want to idle the hose had vacuum also on and off pulsing I guess
