*****UPDATE***** I figured it out...... my plug wires were NOT grounded good. After I grounded them, i was showing a reading at WOT!
Hey Everyone! I'm having a heck of a time with my 90HP Sportjet out of my 94' Regal Rush 14' jetboat....
Here's the scenario....... Its always been hard to start....... usually one person has to play with the throttle at the carbs while the other tries to start it...... once it starts up it dies...... do that about 4 or 5 times, then it will run decent.....
I noticed that when I take it out of gear and push the throttle forward, it wasn't even tweaking the butterflies on the carbs........
To alleviate this problem, I made a longer throttle linkage........ now when you take it out of gear, it will tweak the butterflies JUST enough and fire right up........ however, it was dying every 3 seconds.......
So I took the carbs apart and cleaned everything. It was just rebuilt and I was running double oil, so I was thinking maybe they got a little gunky. Now that is all cleaned up, I finally bought a timing light.......
At idle, timing is showing at 4 degrees roughly......... when I advance to WOT, I'm not reading anything....... its like the timing light doesnt work at all.
Again, at idle, timing light works fine........ when advanced to WOT, NOTHING.
Can anyone help me? I'm at my witts end with this boat and NO ONE will work on a sportjet around here......... absolutely NOBODY!
Here is what I have been following in a post on here:
"Here is how I do it... from the clymer manual... It takes two people... not enough hands. LOL. (But if you have a chance, check out Ken's website. You can click on the Kenimpzoom name next to his post for the link. Excellent advice is there for a SportJet owner.)Assure that the zero mark on the flywheel is aligned when #1 is at TDC.Remove the spark plugs and ground the spark plug leads.Connect the timing light to the #1 spark plug lead.Disconnect the throttle cable at the engine, and move the throttle tower shaft by hand to the WOT position. (this will advance the timing linkage and open the throttle plates)Crank the engine on the starter and note the timing marks on the flywheel rim.Timing should be 32degrees.If not, loosen the timeing link locknut and turn the adjusting screw."
Thank you!
