Working on a new combo....never sprayed a big shot less than 275-300....anyone have any low hp tuneups? 100-150-175-200?

I can do the math buy trying to see what others have used?

73n 63f for 200. Had good luck with this tune and so have others. Might try 73n 60f if it's still a little rich

Seems like a small fuel jet though? I was thinking 73 squared was 175 hit. What flowing fuel pressure?

I have a cold fusion plate, adj 150-300 and have 73 squared and 6 psi flowing pressure on the fuel. Gapped plugs at 31 and pulling 8 degrees timing. I haven't hit it yet due to n/a traction issues, but will soon.

This is from my nos big shot manual..

.047/.053 100hp
.055/.061 125hp
.063/.071 150hp
.073/.082 180hp

Hope this helps.. I'm looking to try a 100-125hp soon on my big shot and work up to 300hp.

Lot of guys say to reverse the jetting. I had my plate flowed by IS and my 200 tune up ended up 73n 63f at 5.5lbs of fuel.
