Inverted.

I think you are correct, Martin but I will investigate other suggestions. I am sure the throttle is opening fully.

Same effect with a new plug & fresh fuel, Don but thanks anyway.

I bought my Laser 150 NIB in 2017, from 2019 it has been flown frequently in a 82" Seagull Spacewalker. I have never been able to get more than 7400 rpm, on Laser 5% & a Graupner 16*8 & using an OSF plug. Last weekend I had to abort a take off because of a loss of power on the 1st flight of the day. On running the engine in the pits the rpm audibly fell & the engine began hunting gently. I used a tacho on the next start & saw that the RPM was 7400 but that quickly by 1000 rpm & the engine was hot. Another start, with a richer mix saw the rpm fall from 6000 to 4300 with more hunting. When I took the valve cover off an inordinate quantity of clean oil flowed out. The engine has never suffered a crash, has excellent compression & the valve clearances are as specified. Ideas please. Tony

My Skybolt was very satisfactory powered by an NGH 17!

I bought this partially built kit a few months ago but I am struggling to find the space to build it. Only the front fuselage crutch has been assembled & this is how I bought it. It comes with the extra optional G/F cowl & is in excellent, original condition. I live in CT13 & would prefer collection but am willing to discuss a meet up. A bargain at £200.

My first flight of 2024, today. The weather at Dover was amazingly good for mid February, gentle breeze & bright sun. I am looking forward to more tomorrow.

Helicoil a success!

A good idea, thanks.

Thanks Both. Looks like I will have to drill & tap M5.

I have acquired a Moki 180 2 stroke, recently, it came without the silencer fixing bolts. I am unable to achieve satisfactory security with M4 bolts & M5s are too big. Can anyone confirm the correct size, please? Tony

To test the system, I bought a couple of cheap items from the UK warehouse last Thursday. They arrived today!

Loads on Ebay!

No problem with the longish fuel feed.

Please see the attached photo. The tank is a square SLEC item, I think 14oz, it projects approx 6mm above the former immediately behind it. Surgery was required!
