Hello Jon, I have sent you a PM. Tony

I will follow up when more info is available.

This is a an experienced colleagues elderly Laser 150, bought 2nd hand several years ago & used in a Wot4XL. The 1st run this season it started as expected & when accelerated the engine stopped suddenly & appeared to have seized. Investigation revealed the damage shown below Fuel used was Optipower 10%. There is no known history of crash damage.

No better for me now, 1730

I have broken 2 white inserts, they appear to have been glued in place! I attach a short length of fuel tubing to the inflation needle & blow as hard as I can!

A very pleasant, late autumn morning at Dover. John & I were alone enjoying the calm, cool conditions even tho' there was a little mud in the grass. Perhaps flying hasn't ended for this year!

My thanks to everyone who responded to my cry for help. All sorted by a new OSF plug-red face!!

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!
