I'll bet the engineer didn't tell you that bolting your carbs down with l-19 bolts is worth 50hp...

I have a question for you guys, I think that everyone so far the has responded to this thread, has a roots blower with carbs that are mounted sideways. So, have any of you checked at what angle they are at while running wot or Idle????? Mine are at 6.7* at idle and at 7* at WOT (depending on water conditions). And it just happens to be that 7* is perfect angle of trust for my setup. Well that don't work out the best for the float levels. Believe me put angle finder on a float bowl and see how much 7* lowers the low sides of the bowls. Maybe it wont make much difference, but I bought 6 two inch carb spacers and am milling them at 7* so when I m at WOT or idle my carbs will be flat level & can set float levels right on. Also the stock car boys have special floats for going around left turns all there lives. They are wedged on the G force side. I was thinking of installing these also, for rough waters running, getting on plane etc.... What do you guys think??????

Mine are mounted sideways. I changed my stock fuel bowls out for the aluminum bowls with large sight glasses. What's nice about them is you can raise the float level to the top of the sight glass, which is towards the transom of the boat. With the stock style bowls you'll be spilling fuel way before getting them that high. With the stock bowls I'd set them to where they are level with the bottom of the float hole, install the float screw, then raise the float another 1/2-3/4 turn. Either way, I've never had an issue float level related.

Quick Fuel makes 1050 marine carburetor with J tubes 2 circuit metering 1.710 venturi M-4710 (can that one be used side by side)
Then there`s a street strip carb, fx4700
Drag FX 4710
FX 4710-2 .. 2x4.. that`s the side by side application?
so many choices..I wish someone would answer the phone over there.

They must be a smaller company than I thought.
