Fed up with Dominator, any ideas on where I can send it ?
I've had this carb for the past 4 seasons and for 3 of them it worked great.
With a .700" , 254/262 dur solid roller cam it would idle at 700 in gear all day long , boat ran great etc.
Well I put a smaller cam in this year (for valvetrain longevity) and am having idleing issues. I think I have this thing pretty close but am at wits end with it.
It was close one weekend, 4.5pv's in it , 90 jets squared. Just a little rich.
I ran a poker run and the boat ran irratically. I later find out that one of the pv's came apart. The little retainer and spring were bouncing around in the float bowl. I installed a 5.5pv (all that was availble this holiday weekend) and dropped the mains to 89 squared. It starts and idles fine just like before but now when I get off plane it won't come down to an idle. I put it in neutral , it will idle at 1800rpms I then shut it down and instantly restart and it is fine again. Why the lean spot after coming off plane ? If anything the 5.5pv should be a little richer at an idle.
I'm tired of working on it. Any suggestions on were to send it ? Quickfuel,BG ?

Sent my dominators to Dean Nickerson. Came back perfect (after providing all of the engine specifics).
Good luck.

Had my 850 done by Dean Nickerson. When I had the engine dynoed the dyno operator told me that it had one of the smoothest fuel curves he had seen. I had some tuning issues (mine not theirs) and they were very helpful. I have had a carb done by Barry Grant and was not happy at all. When I phoned them with a question I got the "how dare you question us" attitude. Do yourself a favour and call Dean.

I had a 1050 Dominator on a 502 with solid roller that came back just about perfect after Dean went through it and made several mods. Ran like **** before that, fouling plugs, etc. Not sure of your motor size, but 90's sound like a lot of jet with PV's. Only issue I had was a lean condition in the intermediate transition (motor would stumble unless I gave it a couple of shots of fuel before I went through..~3000-3200 rpm), the only way I could correct it was to put bigger jets in, but it was to rich on top then. I just lived with it because I wanted a clean transom. Sold the boat at the end of that season to move to a cat. Mine had something like 80 / 86 jets, PV's blocked.
In summary a 1050 was just too much carb for fully ported iron head, solid roller 252/[email protected] .680/.708" on 114 CL, 502 single plane.... IMO.
Dean will work with you until its right, and yours sounds like something relatively simple. My guess is air bleeds.
