Tri Z 38mm Carb Jetting?

[1972mercury]

I've been building up my tri z engine with the yahama wrench report mods and I was planing on getting some v force 3 reeds and a 38mm PWK carb but running little short on money and I remembered I had a snowmobile carb laying around found it it was also a 38mm but round slide but it will do took it apart real clean inside was wondering what jets it had it's got a 45 piolt and a 340 main I'm guessing go one up on the pilot and one or or tow on the main?

I don't think you are going to get an answer that easily. I'd bolt it on and very carefully start to jet it beginning with the air screw out 1.5 turns and the needle clip in the middle slot. Get the pilot right then go to the main. No easy answers for a change like this.

He said he was planning on getting one, not that it was. I thought the same thing as you the first time I read it and then saw the carb:lol:
