OK first of all, I am new to this site, so thanks in advance for any info!!
I bought my 99 GTX with a blown motor took it home and finished removing what was left of the engine. I sent the engine off to have it rebuilt. During the interim, I took apart the carbs and cleaned them, replaced all the gray fuel lines, drained and cleaned the gas tank, as well as, the oil tank.

My new rebuilt engine arrived and I carefully installed it following all the specs and diagrams from the official sea doo shop manual. I put fresh oil in the tank and bled the oil pump. Put in fresh gas along with 38oz. of break in oil.

I tried several times to start it. I primed the carbs and she fired right up, but it would not idle. I have started it several times and it seems as though it is starving for gas. I finally got it to rev up a little and when I did the engine went out of control reving up. I quickly pulled the key and it just kept going. I quickly pulled the plug wires and it just kept going. OMG I finally put my hands over the carbs and smuthered it out. I have never seen anything like this before. I am totally confused:confused: I need help figuring out what happened and mostly to just get my ski to run properly???????????? PLEASE HELP!!! jj

your pull'n air chief, and probably at base of the carbs. if/when next time it happens, pull the choke, hopefully it wont "run away", again.
 
Thanks...I will check that first thing in the morning. I makes sense now that you mention it. I was just scarey watching my hard work possibly go up in smoke. :cheers:
 
problem solved

The PTO side carb's gasket was not installed properly...therefore it was sucking air. Replaced the gasket and presto!!!! She runs great.:cheers:
