Originally posted by Zamboni:<br /> Hopefully someone else chimes in. I recall reading there is a replacable wax pellet in the auto enricher that melts. Auto enricher is known to be trouble prone...if you want pdf zip of 95-97 merc manual I can email, biggerhammer site took dl manuals off.

Any chance of getting an email copy of this manual? I just bought a '95 Dynasty JetStorm with a 120 and it has similar symptoms as being described in this thread.<br /><br />Thanks in advance,<br />Jeff<br />j_mirch at yahoo.com

A few weeks ago i installed a new Auto enricher. The wax pellet is not servicable on it's own. I didnt see any improvements in cold starting. So i am still @ a lost and my wallet is lighter.

Manuals on way Tiflan.<br /><br />Sorry to hear you through money at problem and still there 6x....check your readings with new enricher installed.<br /><br />Sure I read on old sportet forum a post about the guts of the valve and replacing wax pellet-can't find it now.

I recently purchased a 1996 Sugar Sand Mirage <br />with a 120XR Mercury Sportjet and also have cold<br />start challenges. A crazy question.. where is the<br />choke for this model, or is there one ?<br /><br />I would also appreciate a pdf copy of the manual <br />sent to me at caldwell54 at comcast dot net<br /><br />Thanks !

Re: Merc 120 jet cold start problem (1999 yr)

Sure are a lot of guys having cold start issues with those sportjets....I'm going to read over threads at onl sportjet forum to see if a common cause/solution was found.<br /><br />Manuals off to guys who asked.<br /><br />Don't see much useful at that site, helpful guy trying to sell a kit:<br /><br /> http://p081.ezboard.com/fsportjetworldtechquestions.showMessage?topicID=39.topic <br /><br />There was a good thread on fixing the enrichers-didn't imagine that....looks like infos lost. Was a post on replacing pellet/adjusting enricher:<br /> http://p081.ezboard.com/fsportjetworldtechquestions.showMessage?topicID=286.topic

I have a very simular problem with the same engine except it is a 2000. I can detect no power coming to the enricher. A couple of questions. What voltage should I be seeing? The second question is "has anyone ever installed a bypass switch to manually operate the enricher and what results did you have? If possible, please send me a copy or the manual. .bobalford@aol.com. thanks for leting me intrude.

Ya i'm having the issue with my 95 jazz sportjet 120 no primer bulb, no choke, can't find the manual. I have plenty of time to troubleshoot if i can tinker around and get a fix ill post. In the mean time do you mind sending me a copy of the manual also, it would be much appriciated.

My brother just bought a baja splash with a mercury 120. He's having some problems getting the thing to open up. I believe that the previous owner believed it was something to do with the choke but was not sure. Is there anyway I could get a copy of the manual Zamboni? I'd really appreciate it.
