Those jet sizes you quoted aren't like anything I've ever seen for 50hp. For example, a 50-horse dry shot takes about a size 40 of our US size, which is about .85 mm. Regardless, here's an excellent jetting chart:

Retarding 2 degrees for every 50-horse is a rule of thumb. Hope that helps.

Thanks for help, its a MUZZY Stealth Kit ( WET ) and the Jets are in the Kit, for 50 HP. But i want up to go to 100 HP... there is a Fuel Regulator in these Kit...Fuel comes from the OEM ZX12 Pump...

But i give in a NOS Pump, f..k the Regulator, and put the normal Nozzels in it.... i think thats better.

Thanks for Retard information...

I ran a seperate fuel for my wet kit.
26 nos 30 fuel. using the Holley chart it is good for 100 hp.
on a progressive Schnitz controller, 1257 block with JE pistons.

Whats the fuel pressure to the fuel solenoid? (not head, actual flow pressure)

As soon as you know the fuel pressure its all easy from there.

Also when knowing a little timing out of it, try 1 step colder plugs.

Need jets? I got every jet you need for $2.50 each. Flare Or Funnel Or stainless (stainless are $3.50 each)
