View Full Version : Stock Jet Size and other odds

07-02-2006, 02:28 PM
Anyone know the stock jet size in my carb? 89' PS190 351. 4160 carb. I looked at the site someone had sent and they did not list my "list Number"

It has 63's in it now and I am at 6500 feet. Does that sound too big?

Also I have the powerslot 1:5:1 tranny does this reduce the gear or increase? Meaning, on my Supra I had a 1:1 tranny and the RPMS where real close to the speed. With the 1:5:1 would the RPMS be higher for a lower speed in general or the other way around.

One more question, I idle sometimes at 1k sometimes at 750 why would it fluctuate? I fixed the high idle problem I had eailer this week.

I think I have learned more about boats in 3 weeks than most do in a lifetime.

Thanks again for all the knowledge,

I don't know what jet size is required but Vince or Richard @ skidim.com or 1-803-345-0996 can assist you in making the right choice for your elevation if what you have is not correct.
