I have a lot of pops, poofs and farts on decell and between gear changes. Nothing real loud but aggravating.
I am running a 52.5 pilot, a 150 main and the needle is raised .030. The fuel screw is turned out 2-3/4 turns from closed.
I have a Harley dyna muffler and thats when it got bad. There are no leaks. I had none of this with the stock muffler. Well none that I could hear.
I can get it to stop by using a 55 pilot with the fuel screw turned out 3 turns. Not good as that makes the idle circuit too rich all the time but the pops are all but gone. It runs good with the 52.5 or the 55. Both have good performance. I had rather stay with the 52.5.
I read about cutting the spring on the TEV but don't see this as a solution. There only needs to be extra fuel on decell at high engine vacuum. With a weak spring fuel will come in sooner and be too rich when you don't need it.
There needs to be a way to slightly increase the fuel flow through the TEV only during decel at high engine vacuum . Thats when the idle circuit goes really lean and needs a shot of fuel.
What say you learned people as well as shade trees. Is there a way to increase the fuel delivered through the TEV and keep the stock spring so you only get it on decell at the highest engine vacuum.
Or do you have other solutions I havn't heard about.
