2001 SRX700. Ran great last year. Summer storage included sta-bil and cylinder fog. Just started er up and she don't sound right. Temp readings on the exhaust indicate #1 not firing all the time. Replace Denso Iridium plugs with new BR9ECS plugs. #1 still not firing all the time. Plug is wet with gas.

Ideas? coil? wire? bad plug?

Thanks all!

You mentioned #1 not firing all the time. I'm assuming the pilot is partially plugged. Does it fire fine with more throttle?

What he said. Those SRX carbs are notorious for getting the pilot jets plugged up during the off season, even with the preventive measures that you took.

I would bet that by removing the carbs and pulling out the pilot jet on each carb and cleaning them you'll be running smoothly. I would clean each pilot jet, not just the one from the cylinder that's giving you the problem now. The holes in those jets are really small and it doesn't take much crud to create a problem like the one you've got.
 
Hold on now boys

Did you check to see if you have spark? Why dont you do that before you go pulling the carbs.

If I didn't drain the bowls on my 99 sx 600 or my Viper, 100% of the time I had a plugged pilot jets in the fall even with stabil. The last few year I have drained the bowls they have not plugged and started it right up.
 
Yes, I have spark. So despite my efforts last year (clean carbs, stabil), I should clean them now before the season. I guess I won't be cleaning the carbs each spring from now on!

I would be concerned about draining bowls. I've seen little rubber gaskets dry out without gasoline to keep them moist. I've always heard "keep fuel in it".

OK, I'll buy all this if someone can explain why the plug is wet when I remove it. If it ain't gittin gas, it shouldn't be wet, right?
 
ONe would think that if you have spark and fuel it will fire, you could test the plug cap and coil without too much trouble, I have had to replace a number of plug caps in the past. The cap need to read 5K Ohms, and if you don't have a service manual a shop might give you instructions and specs on the ignitions coil. This could be done prior to pulling the carbs. But pulling the carbs prior to riding is cheap insurance against a burn down early in the season.

There really isn't any "perfect" way of storing them for the summer. The guys in the "leave fuel in it" camp risk having to pull the carbs and clean them and the "drain the float bowl" guys run the risk [although very slim] of having seals/gaskets dry out on some models.
 
sta bil

i guarantee its a plugged jet from the stabil, it may work good in the gas tank itself but if left in the carbs over summer will gum up your jets
 
SEAFOAM! I have seen hundreds of plugged and gunked up carbs that had Stabil in them. Store all my power equipment with Seafoam. NEVER, i say , NEVER had a dirty cab part on my sleds since using Seafoam only. Those pilots on the Viper are TINY!! Every time I pulled them they were spotless. Get them cleaned and use the right stuff to keep them clean.
 
I am also a supporter of sea foam....But I am not comfortable hoping it cleaned everything 100% I'd hate to burn down because of a partially plugged jet. Since clearing the carbs isn't a huge project, I always just go ahead and do it. To each their own right?? :)
 
I use stabil every year, put it in the tank on the last ride. Never had a plugged jet but still check the carbs every year, not worth the risk. Carbs have always looked good when I check them. I don't drain the carbs. Call it Murphy's Law or whatever, seems like some people get away with it and some don't. I would still ALWAYS go through the carbs every year.

Back to the original problem. It's possible to still get some gas, hence the wet #1 plug, but it is probably partially blocked and not getting all the fuel it should. I also think cleaning the carbs will cure your problem. It's the first thing that needs to be eliminated anyway. You need to look through all the jets and make sure you can see through them. I spray carb cleaner through them, and then air. The pilots are the worst to get clean. I use a welding torch tip cleaner to run through them (my old exciter was always gummed up!), carb cleaner and air usually WILL NOT UNBLOCK THEM. I've even plucked a strand from a wire brush to run through them, it works in a pinch.
 
Thanks for all the suggestions. I go through the carbs. If ya don't hear back from me, then that did it.
