Yeah! I had no idea I would be able to still hear it from so far away. It sounds a little warbley just before it is on the pipe, and I am not sure if it is the audio or or real. I am going to have to maybe use this as a tuning aid.
With alcohol carbs(V8 car engine) I have removed the floats before, and using basically the same idea as you are, but I drilled a hole in the float bowl at proper fuel level for my return in order to maintain the correct level. My catch tank didn't have any pump to push the fuel back to the tank, but it didn't run long enough to fill the gallon tank.
@@SpeedofCheeseRacing it's strange the crazy things we come up with just for a few HP here and there, but I always enjoy how you think differently from most people, out of the box thinking isn't always the best but I have found that you learn way more trying crazy things than just doing what everyone else is.
If you're ever struggling to drill exactly the size hole you need for a jet, consider pressing a watch jewel into a brass carrier. They come in lots of sizes and they're super accurate, don't corrode or wear.
@@SpeedofCheeseRacing oh, I mean actually leaving the watch jewel in the hole. They have really accurate laser drilled holes though them. They're like little sapphire donuts.
I love the outside the box thinking, that's a smart solution! :) That pump is specced as 65 liters/hr so it's not going to keep up if you're filling the reservoir at 1.3 gallons/minute. Maybe an electric pump would keep up if your current solution ends up not working out. Or you could put some main jets in the fuel line to adjust flow to the reservoir. What size main jets does it like? I'm working on an 873cc 4 cylinder that I want to run on methanol and was planning on using 38s on it too, would be nice to have somewhat of an idea of what range of jet sizes I'm going to have to need :) I have no idea atm, could be 400 or maybe 1200..
Jets in the fuel line is exactly what I did. :D Seems to work pretty well. I ended up with .116 mains which is bigger than Mikuni makes so reamed them to size. I have mains up to .123 if I need. I am at 4200 feet and run at 200 ft, so I hope I have enough to get it to run there.
Cool, thanks for the info! That means I'll have a valid excuse to be cheap and just drill/ream my own jets and I won't have to buy any :) I am currently running my 335cc single cylinder on E85 and my main jet is about the same size as yours, pretty close to getting into the threads. But I am probably a bit overcarbed with 45.5 mm, I wish now that I had taper bored it instead. I don't think I can drill large enough for methanol and this carb size so gonna have to get a new carb.
Drill your needle jet to 120. Find a tapered reamer ream to 122 to 125 at the opening. I think 6fj40 needle with 113 to 116 main 40 pilot can't remember how big on the power jet 3.5 float valve. We ran a mikunis round vacuum pump 270cc honda in a micro midget blendzall 4oz per gallon
Im really enjoying this build. Why cant you just run a fuel pump, a little bit of pressure would fix the problem? I would think you would be far better off running the float assembly. The methanol rd400 i have runs two taps. Its nowhere near as extreme as this tho.
