I have an Moki 2.10 and am running it inverted in a Pica 1/5s. p-40 Warhawk. I am Having Problems getting it started. I use 5% sig 1/2 & 1/2. It justs wants to flood. I use an K&b 1L plug and OS-F plug and am running out of options. " will an Cline pump help?"
NEED HELP....

Your problem is that the engine has too much fuel in it and it's flooding the glow plug. This is a problem with inverted engines. If you're priming it either with raw fuel or by choking off the carb, try a lot less. The plug and fuel you are using is fine and is not the problem.

Ron, Thanks but do you think a cline pump will help with that and is there a trick to starting it?

All the Cline pump does is regulate fuel pressure at the carb when the engine is running. Your problem is not too much fuel pressure, unless of course your tank is located way above the carb. I haven't had a whole lot of experience with inverted Moki's I just know that Moki or any other brand can be a problem inverted.

Are you hand proping or using an elec. starter??

I would try drying out the plug and connecting the glow driver without any priming at all.

Ron

Ron, I am hand propping.
Thanks for the info. I will try the things that you suggested.

I had a love/hate relationship with my Moki 2.1 for over a year and a half, and almost gave up on it. Mine is mounted sideways in a Midwest 300XS. Three things made a big diffference in this engine: 1. I put a Cline fuel system in. In addition to pressurizing the tank, the regulator allows consistent metering of fuel to the carb. I ALWAYS use an electric starter. I broke a couple of props trying to hand start it with a big chicken stick. The first start of the day really requires a starter. 2. I use 1 gallon of 10% nitro with all synthetic oil diluted with 1 gallon of straight methanol. The result is 5% nitro, but more importantly the oil content is reduced in half. Jim Cline says you almost don't need any nitro at all. I had been using mostly castor at about 18-20% oil content, and the engine just would not turn up. In fact, I eventually cooked the ring unto the piston as a result of using too much castor oil. 3. I use a Zinger Pro 18-10 prop and the engine really turns up. It took my sending the engine to Jim Cline to get it right. He is a great guy and really knows his stuff. I found his recommendations hard to believe at first as I had been in R/C for over 30 years, but he is right on.

The Moki likes to start wet. This is not good for an inverted engine! With the Cline regulator, several revelutions must be made to build up pressure requireing a starter.
Mine is side mounted and I have to crank it about 30 sec before it will start with a starter. I have the Cline system.
Mine will start by getting it quite wet, flip it 2-3 times then attach the glow plug and flip it backwards using the spinner. With a chicken stick it will brake the prop.
With an inverted engine, I would turn the airplane over and start it. Especially when cold.
