I have used the Cline regulator system on both O.S. 160 and 1.20ax. Works absolutely flawless. Never have to re-set the needle, never goes lean, and will not let fuel to the carb at any time. You guys either have a faulty set-up, or a bad diaphram in the regulator. The perry pump is no way a better solution to delivering consistent fuel flow to the engine. I use the 120ax in a competative advanced pattern plane with over 60 plus flights on the current set-up. Over 100 flights on the 160fx. So not sure why you are all discounting the cline system.

I've also used the Cline system successfully on two Moki 1.80 setups. I've also used the VP30 on 3 of my own OS 1.60 FX setups and have helped about 8 local guys do the same. The VP30 is 1/2 the price and is "fire & forget" once it's set up. When you do it right, the engine is super easy to start and there's nothing to worry about. You never have to mess around with a pressurized tank, no worries about whether your check valve is still working right (get ready for that someday), no worries about the nitro in your fuel eventually desolving the CA joint for the nipples on the regulator body. That is also going to happen to your setups, so be sure to always have alchohol, Q Tips and CA at the field with you so you can clean it up and re-attach. No maintenance on a diaphragm either.
I'm sure the VP30 doesn't last forever, but it seems to outlast the Cline. That's my experience from many hundreds of flights on both setups. Anyhow, fly what's working for you. I liked the Cline when I first used it, but I've found that there is a better solution.
