Default RE: Walbro conversion for OS 160FX

Thank you Benoit,

Ok Here's an update on the project:

Im going with a walbro carb conversion for this project, as it has a diaphram pump and regulator on it and meters easier than glow carb.

Actually Ive run into a problem today. I received my package of walbro carb, gaskets and adaptor flange for EVO26.

The flange has a 17mm outer diameter throat and 160FX has a throat of 15mm. so unfortunately its not a bolt-on fit..

The good news is the walbro carb clears the thrust washer so it wont be a problem once I sort out the adaptor flange.

On another note, this engine with gasoline is doing fantastic!

Here's a couple of RPM readings (with glow carb) you all will enjoy:

All with Bisson Pitts muffler - same day, same fuel.
using single 1500 mAh LiPo cell to power RCExl ignition.

APC 17x8 - 8400 RPM
JXF wood 17x8W - 7800 RPM
JXF wood 18x8W - 7400 RPM (unbelievable thrust!)

The transition is incredible even with 18x8.. no lag what so ever, can idle around 1600 rpm with ease..

I will upload a video of the engine running soon.

I also want to say, one of these conversions will be used with a MVVS 26CC tuned pipe. I bet the numbers will go up even more!

This might turn out to be the best 26CC conversion.

Im still using the 7:1 oil ratio gasoline, buy I will drop to 10:1 once I sort out the walbro adaptor and report back with all the tach readings.
