Model Forum / Radio Controlled / Air Models / October 2006Saito 180 Exhaust pressure/Cline Regulator
I can't get enough exhaust pressure to pressurise the fuel tank when using a cline regulator on a Saito 180. Has anyone else had the same problem? I have change the one-way valve and made sure it is installed correctly but still have the problem. I have a Saito 82 and it works fine. >I can't get enough exhaust pressure to pressurise the fuel tank when > using a cline regulator on a Saito 180.

He's probably diagnosed every possible permutation of a problem with his product.

If it is stock, if you can stand a little reduction in performance, try adding a addition tube on the exhaust outlet. A little back pressure might be all it needs. A tuned pipe could do the trick, too, if the tap is put in the right place.

I could install a new outlet in the manifold before the silencer to see I get the required pressure. >>> I can't get enough exhaust pressure to pressurise the fuel tank when >>> using a cline regulator on a Saito 180.

Instead of the stock one way valve (small pinched neoprene tube/brass insert), I use a YS one. This one is a real one way valve and I had no problem to pressurise my tank. On your big 180, muffler pressure is certainly more than adequate. You may try to slightly bore the tap, but a good oneway valve is a must.

I agree with you on the stock one way valve it only need a bit of oil to block it and then you have a dead stick on your hands. I have ordered 2 x ys valves and will drill out the tap. Thanks for the info PAU |
