im sure theres no real difference that you could ever feel. But theoretically it lets the diaphragm fluctuate with less resistance. One more update.... NEW TOY! Thanks to ShoNuff, this should match nicely with my c75 hub 9/17 hooker impeller.

Wood vinyled pole. AWesome!

Out on Friday. This time 2 packages.

Back on the water today. Put 2.3n/s, 120 hi, 120 low, gold 115 springs. The thing rips. Definitely capable of backflips. I'm set at 1 turn out all the way around and its running rich, it started to show signs of fouled plugs after 1/2 gallon run through. Then I let buddy ride it...

On a side note. I have 4 springs laying here brand new from a rebuild kit. They are identical to the pictures posted in length... but now the gold is longest. From longest to shortest, I have Gold Silver Black Silver I cant tell a difference between the two silvers. Is the shorter...

No jets today. Riva didnt ship the parts out yesterday even though I ordered them at 11am. Oh well. Goin to spend the rest of the week in north tampa. Perhaps sunday I'll get it goin. Now to figure out what spring I should use to achieve 20-25 pop off. As for a race. LoL...

Waitin on the jets and seats. Should be here within the hour. Then off to the lake!

If youve done a 750/550 conversion before you know that a extremely aggresive blue printed pump and tuned impeller is KEY. And yes, a properly setup pump will hook decently. You should also just go ahead and take your motor out and put many many layers of reinforcement in that ski. I...

Blocked crossover allows for stronger signal to both carbs, when you fill it, your going to have to drop your pilot jet up to 10-15. Its pretty neat. Perhaps even your main jet 2.5-5 as well...

the easiest thing to use is QuikSteel from advance or someplace. 5.49 a tube. Kinda looks like a little debbie cake roll. You mash it with your hands and just shove it in. It seems like its not going to stick for the first 1-2 minutes as it will just pull back out with your fingers but...

Almost finished! Powdercoated the headpipe today, did a neat blend. Unfortunately I forgot I did the manifold in Satin black and I did the headpipe in texture black... so they dont quite match. Got the motor back in the hull, 1 motor mount ate the dust in the process. Right now...

Fill the crossover, and get your limited chamber back.

So Tim told me the cylinder was ported by a guy named Scott Palmanofski or something of that sort of last name. He recommended 20-25 psi popoff, a needle and seat of 2.3, a pilot of 115-120, and a main of 120 for starters. Gonna try to get those in a bit.

Indeed. Ive thought about that too. However without a syphon tube reaching down to the bottom, your cooling water will seemingly accumulate at the bottom half filling both chambers?

I have same problem with my b pipe. As soon as I shut the motor off, it rapidly cools, and sucks water all the way back filling the crank case. I just havnt been able to figure out a way to make a small enough waterbox yet.

What a tool.

What?! no pump yet!? You gotta be jokin. I sent that forever ago.

Well since the shed is Waaaay to dusty from all this sandblasting and powdercoating I've been doing lately, I went ahead and assembled the motor with a new piston in my room. Shes cute. Now I just gotta put the electronics on it, bore out the FPP manifold a bit more, and put it back in...

Got some crusty old carbs from a 760. Eventually they will be sent off to become blackjacks, but until then I made them work. Pulled them apart, and they were just as nasty on the inside as the outside. After 2 days of acid dip, they went into the sandblaster... then back into the...

Alright, Ive read the watcon writeup. I'll read over it again and get it all fresh in my mind. I guess what I was really asking was, 44s are far more susceptable to N/S errors because of the lower pressure, unless 38s which seem to run fairly well on anything from 30-55 psi depending on...
