Other Primer seized

Second year in a row my plunger primers have seized up. First year I drained the gas and did nothing else. Last year I ran oil through them.. didn't work. Any suggestions? Do bulbs last longer / work better?

Thanks,

I put in a new primer every Spring before my first ride. I've had too many croak mid-season. $12.00 and they're easier to replace while my ski is in the basement instead of on the ramp in the lake.

Well I had bought two new ones already. Went to switch them out last night and both the old ones were working again..?.. I tried the WD last year and couldn't get them to break free. It would be easier to replace them now and not have an issue all season but that would be too easy. I'll keep a spare with me and change it at the lake if I have to.

I would think a bulb under the hood would be a pain in the butt. I have to prime mine every time I start it. Sometimes I have to prime even if I've been riding for a while and just fall off...

Sounds like you need to tune your ski.. I know that can be easier said than done... I dont have primer at all and my ski fires up instantly.

I agree with the under the hood deal. Too much of a PITA. Mine was under my hood when I bought it, but then I ingested water once in the middle of the lake and I was :):):):)ed, since there was no way I was pulling the hood in deep water to get to the primer to purge the water out of the carbs. After my long swim to shore, I rode home and immediatley and relocated the plunger to the dash.

I spent a good bit of time messing with the carb last year. I had issues with it dying at high speed. Got that fixed and it runs great low and top end. I could be a little lean on the low end but I think if I was lean enough to cause starting issues it wouldn't run good at the low end.

Might be a small air leak. I have to prime every time I start if it has set for any amount of time and maybe once or twice all day while riding.

whats your compression? could be a sign of a weak top end

Never checked compression. It's not weak (stock) top or low. Runs great. We have 2 sxi's and they both need a little shot of gas to start up every now and then. I've run against 5 other sx/sxi's and it's been even or faster every time. The more I think about it I don't think the low end is lean either. If I'm on the water it has pretty good snap in the low end. It does seam a little slow trying to come up from a sub but I think that's just the stock ski trying to pull my fat ass out of the water.

On a side note I ride between 5-6K above sea level. We took them out to Kentucky last year. I think we were a couple hundred feat above and I was shocked the difference a little more air made.

Same problem this year. Got a new to me SJ and had the same problem on a primer that was installed 4 months ago with nothing more than a few start ups through it. SJ starts without priming my remaining Sxi won't... go figure :)

Anyway anyone with the same problem heat from a hair dryer freed it up.
