32:1, Walt Conner

I am assuming you drained any old fuel/oil and mixed up a fresh batch? Yes it could be the fuel line or screen in the fuel tank partially blocked. Also there should be a screen covering the main jet (fuel chamber has to be removed to get at it) that could also be blocked. If the mower was sitting for a long time with fuel in it, you need to check all of these things. The float, needle and seat are not difficult to replace but they might not be your problem, look for a blockage first.

iowaboy ... I was cutting grass under moderate / light load. I've since re-tested the 10323 with stock jets ... 1999 10323 "E" Duraforce ... burned 12 oz of gas in 38.67 min - 0.31 oz/min ** Correction to previous 10323 test ... carb had a #67 drilled main jet & #78 drilled pilot jet. Note that this later test was done starting out with a drained fuel bowl AND tank before adding 12 oz of gas. I first added just a few oz. of gas to see how well it ran ... it ran good so I cut grass until it died. Then added my 12 oz. and ran the test on an already warmed up engine (figure warm-up time it another variable that should be eliminated for fair comparision). Realizing my first 10323 & 10424 tests may or may not have had gas in the carb fuel bowl, I re-tested the jetted 10424 just as I did the 10323. 2003 10424 "E" Duraforce ... burned 12 oz gas in 24.2 min. - 0.49 oz/min (#68 drilled main jet & "40" Suzuki Pilot Jet) This was a 19.5% increase of fuel useage ... empty vs. possibly full fuel bowl plus grass cutting load was more moderate even sometimes heavy this time. What is amazing is the comparison between these two latest tests ... stock 10323 @ 0.31 oz. / min. vs. jetted 10424 @ 0.49 oz. / min. ... a wopping 58% difference !! You also got to figure the 10323 has a drive load on it (including added higher speed 10550 gears) and the 10424 does not. The jetting on the 10424 is the absolute minimum (next larger drill size on main jet and "40" Suzuki jet is slightly smaller than the next larger #78 drill size). Also the 10323 has a lot more hours on it, but always ran perfect without even a hint of surging before jetting. The 10424 surged real bad when new and is only on it's 2nd mowing season ... rotated with my other mowers so you might say it is hardly even broken in. Next week I'll re-jet the 10323 so it is identical to the 10424 (1st test it was actually jetted one size richer on both main & pilot) to see how jetting really affects this mower. 7024 & 10301 had been run dry prior to my tests (7024 is retired and gets used only a few times a season / the 10301 still has the snail-speed gears in it so I don't really enjoy using it) so the only diffence in their tests and these new tests would be running time from a "cold start".

I have checked the coil several times and it always is putting out a strong spark when it want start.When I pull the plug out and spin the engine good and hard then put the plug back in it will start right up.I have ruled out flooding as a problem so why would spinning the engine with the plug out seem to fix it?
