Carb Question

I recently replace my Holley 4010 with a brand new marine 4160. Testing it in the driveway, it didnít seem to idle perfect. It was good just not perfect. Following advice from here, I sprayed carb cleaner around the base to see if there might be a vacuum leak. It appears there is a slight vacuum leak at the secondary throttle shaft. The RPMs increase by approximately 50 when I spray the shaft. (Verified by the tach on PP). I havenít had a chance to do an on water test yet.

Based on this thread, http://www.mastercraft.com/teamtalk/...ad.php?t=61436, and others it seems other people have experienced a similar situation. However, I havenít found a definitive answer as to whether this is common and/or acceptable. More importantly, is it unsafe, i.e. could it lead to a fuel leak.

I intend to call Holley, but first I wanted the groupís opinion.
Thanks

if it's brand new - I would contact the reseller who you bought it from - or follow whatever warranty instructions you have.

Also, once you get the vacuum leak eliminated, you may have to adjust the idle slightly (600--800 rpm in gear at idle if I recall correctly).

As far as fuel leaks go, do not over tighten the fuel line connection to the carb. If you do, it will likely leak. I can't recall the torque specs, but you don't want to exceed them.

To close the loop in case anyone stumbles onto this thread. I called Holley and was given a few suggestions. I also called Discount Inboard Marine (where I bought it) and talked to Vince. Great customer service. Both the Holley Tech and Vince said they had not heard of this before. Vince put me at ease regarding a fuel leak. So I checked it again. It turns out that the vacuum leak appeared to be just below the throttle shaft so it seemed like it was the shaft. I guess in my attempt to not over tighten the carb and warp the base I did not tighten it enough. A little tighter and it is much better.

Carb help

I have a 93 mastercraft maristar 225 with the indmar 351 and a holley 4010 carburetor. I am having some trouble out of the carb. It dies when you hit the throttle hard, I have to ease into it. then it runs great. Sometimes its worse than others. I just rebuilt it with a holley kit. Much better than the beginning of the season, but I am tired of it not running right. Every where I read say to get the holley 4160 carb. but there seems to be so many different ones. Can someone tell me the list number on the carb I should get. Seems like the Holley site says to get the 0-80319-1. However, I don't want to buy the wrong one. Any suggestions here about which one and where to purchase would be greatly appreciated. thank you in advance.
