this is my first time posting although I've been an almost daily visitor since I found out about this page a month ago. usually can find what i need through search but can't find definative info on this.

have a 89 190 with the 4160 carb, had some problems with a leak out of the forward diaphram and replaced that, returne the carb, adjusted the choke and have got it running (rough for a bit, I'm pulling her out of storage for about 3 years) I'm pretty sure I need to get it refreshed or rebuilt to get her running right but after deciding that i need a rebuild,

I've notice that there is gas at the gasket between the carb and intake, followed the gas and it looks like the trottle linkage also has some gas on it as well and it is coming from around the linkage and flowing back down the gasket to the rear of the boat.

CAn this be fixed? i've read a couple of comments that say if it is leaking here then it is better to by a new one? don't want to drop$450 on a new carb, but don't want to waste time and money if it is a goner.

Anybody dealt with this? any info appreciated.

i've looked into the rebuild, but will it address the gas leak from the throttle linkage that i have?

or fix that would require more than the rebuild?

thanks.

I know!!! I know!!!


I'm asking about the leak from the throttle at the carb, will the rebuild take care of this or will it take more/unfixable?


thanks tho

thanks thoYes.............

Do you have the crappy instructions or the nice PDF version? The kit instructions leave a lot to be desired.


Is the evidence of gas a leak or residue from fuel presence? A hard to word question but is it leaking in a dripping manner or just residue on the throttle linkage?

don't have any instructions, haven't got the kit yet.

i'm not seeing any type of dripping, but there is a wet spot (gas) under the throttle linkage and where the linkage connects to the carb there is residue. also, under the linkage down the side of the carb there is wetnes as well (gasoline) and down the gasket to the rear.

as far as fuel presence, all around except for the spots i mentioned it is dry/no leaks.

Put the rebuild kit in and clean up the linkage. It's all good from there. You'll be just fine. I have a nice set of instructions in case you missed my comment on the crappy kit instructions.

PM me your e-mail address and I'll send them your way. A nice Powerpoint and MC is too skEErt to allow a PPT file extension in the attachments...

i appreciate it

i've seen some comments on this forum that said that if there is leaking from the throttle linkage then it isn't worth rebuilding. any word on if that is true?

i'm new to carbs and motors in general, but am learning and have done some work on my own. I'd like to do the carb myself if i can, but don't want to get halfway into it and find out that the throttle may be more than i handle.

how can i get good instructions?

thanks again.

I would hate to second guess something of that nature but I can't see that being the case. I'd call Holley and talk to them on Monday. They are good people to deal with.

For myself, I have not seen that to be the case.

Calling them is not a bad idea, also give this thread till tomorrow afternoon to get some attention... folks are still out on the lakes today(lucky ones anyhow)

yeah, i wish i was one of them

thanks for the help guys, it would be great if i only had to put in the rebuild kit.

i've been able to get it running and such and have had it on the water for test drives up and down the river (don't want ot get to far) but the carb is unrealiable as it is (won't start up always, runs rough, etc., but when i can get it going it will run fine)

i'm amazed at how tough it is though, never went totally dead on me (unless battery problem) and it started right up after about 2 1/2 years of nothing (after a solenoid change and charge)

I think it warrants a rebuild. IMHO, $30 to find out if it fixes the problem far outweighs $400 for a new one. Plus, if it can't be fixed by the rebuild kit, you can easily sell the old one for $30 all day long on ebay in non-working condition. No harm nor foul, just a few hours time delay to see if the rebuild works.

welll the kits from skidim cost around $50 if i'm correct.

called skidim and talked with one guy who wasn't familiar with this problem, called back and left a message. also called Holley and sat on hold for about 15 minutes till i gave up, will call them back tomorrow.

i'd rather not go through the trouble of putting in the rebuild unless there was a pretty good chance it will fix the problem

thanks for the help, anyone had this problem before?
