ok up date , pulled the sediment drains , pto had the most fuel drain out , pulled the plugs , with the drains still off pulled the cord , I m just getting dribbles of fuel out , would think with this 1/2 in fuel line I would be getting a lot more , I did pull the in tank line seems ok , if the needles were stuck closed I would not get any fuel out of them at all , I have never seen what normal fuel flow should look like off of one of these pumps , my guess its set up for high volume ,and its a dual feed,, should have some pretty good blast out of the drains , opinions please

Pulse fuel pumps don't deliver much fuel at starter rpm. That you got some says you're getting fuel TO the carbs. The most common issue with lack of fuel FROM the carbs is dirty jets, like 90% of the time. Pull the carbs and clean them. No parts needed. There are cheap tools for cleaning jets and flow passages.
Also, water in fuel is a very common issue. So, while fuel Iines are off, get fuel to flow from the tank by gravity or pressure. Use a clear glass container to inspect the condition of it. Should be clear as water. Yellow to gold color is bad gas. Let it settle for 15-20 seconds and any water will settle into a bubble at the bottom. If in doubt, just remove it completely and put in fresh gas.

i have sprayed pre mix while running into both carbs no change , after a repeated test, appears center cylinder suctions is less on center cyl, any clue on that

You sprayed gas into the carb throats and it still won't run? No spark or way out of time.

You spray down the cylinders with mixed gas from a chainsaw or weedeater and never starting fluid unless it has the oil mixed in not the carburetors when doing that.

Agreed with KC check compression on all cylinders with WOT hot and cold.

If those come out right then I would look into a fuel pump before spending money on a CDI or stator. Cut back a 1/4" of the spark plug wires and put new caps on also.

sprayed fuel thru carbs no change compression changed hot to cold on center pulled the jug i dont see anything wrong , ring gap looks good

 

[polaris754]

compressdion cold was the same ; looking at that , not a good gauge , but was equal did a hot run
pto only center was down 20 psi , pulled jug , looks ok , ring gap ok

 

[polaris754]

remember his is 2 cyl down ,, thats what is bad never seen 2 at once, some say its the water pump , no coolant leaks

 

[polaris754]

run this up 5 6 g cold center and mag pipe

 

[Coolhand]

What is the exact compression numbers? Need to know that and do gas down the cylinders not through the carburetors.

 

[polaris754]

its not a good tester 125 across

 

[Coolhand]

Rent one from autozone or oreillys for a day and check.

 

[polaris754]

it is from oreillys neighbors otc reads140 a hole cold,, when I checked hot center dropped to 125 , so I pulled that jug , shows signs of blow by, still cant see what's wrong why center and mag are nor firing,, right now I have filled the case with trans fluid to check for leaks

 

[kccats]

If your cases had a leak it would have locked up

 

[polaris754]

been 2 days no leaks seen from case , i would think if the water pump was a issue i would have trans fluid leaking out the weep hole has anyone seen a case crack internally cause this , this is not making any sence
