With the 951 engines, that compression isn't bad. How is it running?
It cranks fine, but just seems as something is not letting it fire up. When i checked my spark plugs, my left spark plug was brown color, but my right was dry, even though i turned the adjustment all the way counterclock wise, the only change was that there was a little bit on fuel on the right spark plug, but barly.
What may be causing that theres no fuel
Spark is blue on both.
What can be wrong? thanks. I just remember reading that 130 psi was the lowested before it needed a rebuilt and 150 was great.

150 is the compression for the 717 and the 787 engine. You have the 951 engine, right? What color fuel lines does your unit have? If they are the stock grey lines they need to be replaced. The carbs would need to be cleaned, along with the fuel selector.

The stock grey lines deteriorate from the ethanol in today's fuels. You will need 1/4" and 5/16" fuel line and about 20 stainless steel clamps. I got mine at NAPA. Most auto parts stores will have it. You don't need the high pressure fuel injection line. It's more expensive. You would disassemble the carbs and clean the filters in them. The fuel lines come from the tank through the selector. You would remove it and clean it out as well. Replace the lines one at a time so you get them back in the right places.

I got a roll (20' I believe) of the 1/4" and had quite a bit left over. I think I got about 9' of the 5/16".

The 951 engines use both. The smaller (717 & 787) engines only need the 1/4".
Hello everyone, I know that I have been absent for awhile and have not been able to keep you up to date due to my job.. But this is what I have done so far.
*Replaced All the gray fuel lines.
*Took out the old fuel, and put in new.
*New oil
*New spark plugs, Blue Spark.
*Cleaned Carbarators
So good news is that I am getting my beeps now, so my ski is "ok" I guess.
Though for the first time I am getting the "Oil Low" warning, not sure why, have half if not more of the oil tank filled. Had a compression test, 125 on both. One of the spark plugs head is chocolate color, so that one is fine, though other is still white, but is somewhat wet. I may need to turn the adjusted abit more.
But problem still is that its not starting, Engine is cranking. I wish this was just a car lol, I am better with those.
Anyways, if you guys have any ideas with what else I can fix please let me know, Its really appreciated!

Alright, maybe the oil is under the halfway but not to far if it is, Somewhat hard to see.
Well I really don't know, I mean I try to start, and it just cranks.. I have tried holding the throttle to see if it would keep going. I just feel like I will never start it. =\ Not trying to bug you guys or anything, just don't know what to ask anymore.
Do you know how much I need to turn the adjusters for one ones that control the fuel flow or w-e.

Low speed is 1 1/2 turns from closed. H speed is 0 turns
Can you verify you are infact getting fuel to the carbs? If you replaced the lines, it takes a while for gas to fill up the lines..
get a little squirt bottle, fill it with premix and put a little down each spark plug. Also, replace or dry out your plugs, they may be fouled, or wet.

Yeah I think it was because i just got new lines and have not started the moter for awhile. I just had to just the choke a bit more, and got it running. Now it start right up from the first push of the start!
Im really happy because I may acually be able to take it out for this summer haha
