Supra Saltare in France

[86 century]

The 1 1/2 turns is a starting point. Just so we know where were at check the float settings and power valve if it has poped back through the carb it could have taken it out.

Get the eng running turn the screws in one at a time till in nearly kills the eng.
Then back them out till the idle smoothes out. It may take going back and forth a few times to get it right.

From one eng to another the final setting can be vastly differnt.

Thanks century, I will tune it as you describe next time I run it. And keep you in touch

First cession of my friend. 32km/h at GPS, no ballast, just me in the boat :

Definatly in love with Supra Boats. The Saltare is the Best low cost choice we could do ! Today was shinny and 24°C, water 12°C, 4 people in the boat, 1 rider, good wake, good vibe, alot of Fun !

I have an oil problem. When I shut off the engine, some oil is going out from exhausts. I read that it's maybe tired piston rings, or valve seats. The engine is 250 hours. It will be too much work for me, so I simply will check oil level and often clean spark plugs.

I'm also close to place an order for a 4160 E85 conversion kit. Here in France E85 is half the price of gasoline. So it will be an economical upgarde.

I'd be careful on the E85 conversion. Ethanol loves to attract water and quite frankly, having the boat on the water with E85 in it is just asking for more trouble than saving a buck or two on a gallon of gas. Plus the E85 doesn't usually produce the same amount of power that a gallon of normal gas does.

Hey Ben,
I use my boat daily. E85 attracts water when sitting a long time in a non moving tank.

I already did an E85 conversion on the old Peugeot 205 of my gril Friend. I simply drill the jet 50% bigger, tune idle jet, and give 5 more degrees on timing. The engine was alot more torquy. It was an 1.3L and works like a 1.6L after conversion, with only 20% more fuel consumption on a half price fuel.

We do 150H of wake per years. That means 3800L of gasoline. Means 6080€/year !!! It's definatly not a buck or two to get 30% economy. Remember I'm not living in US, here gasoline price is a real problem to our common passion

Would realy like to know how the convertion comes out.
I have considered doing the convertion to mine only thing keeping me from it is not being able to get e85 on the lake.

Hey guys,
Today I tried to tune the engine, to get less black smoke at idle.
So I warmed the engine (I did 2 wake cessions before acting), and start to trun mixture srews. I tried with 1/4 turn each side, and each time. When I srewed, rpm rised, so I unscrewed idle screw. It started to smoke less, but I finally turned srews to maximum ! And the engine is still running. Running good actually !
Is it normal ? My carb is a holley 4160 with 1 metering block with 2 mixture srews on 1 side and a jet plate on the other side. Is there an idle system on the jet plate side ?

[86 century]

I dont think any of the holly vacuum secondary carbs have four corner idle.

I could be wrong unless some one has modified the carb.

[Sdc77]

Ok. Any idea why the engine is still running with tightened screws ?

Here is the wake, no ballast, no extra weight, 3 people in the boat, speed 20MPH :
