I have an old os 32f engine in an old concept dx,It is running on irvine sport 5, 5% nitro fuel,the only time I get the engine running right is when it is to lean and overheats very quick,Im going to try higher nitro fuel starting with 16% duraglo(its all thats available at locol shop) any suggestions on other fuels or anything else to try,I know its an old engine and heli but they have had very little use before getting stored for 6 years,want to get it going to learn on as want to get airskipper 50 once I can fly half tidy.

The 32F-H was, and still is, a good reliable, easy to tune engine. It should run well on %5 Nitro fuel but what is the oil content of the fuel?
The 32F-H is the predecessor to the 32SX-H. I suspect you might need to clean out your entire fuel system if the Heli has been sitting for that amount of time plus re-setting the high and low end might help you.

Depending on where the stuff has been stored for all that time, it wouldn't be a bad idea to go through the engine and just make sure there is no corrosion or gumming. Give it a good cleaning and re oil it it should be good to go. These engines are pretty tough. As far as nitro content, that's going to be limited to whatever is available to you. I've seen guys run 30% in the 30's and have no problems.

Thanks for the comments,Ive cleaned the whole engine out with meths and stripped and cleaned the carb 3 times now,Ive also checked the fuel system,the tank was a new one that has never been fitted to another heli,all the fuel lins are new,however when I stripped the carb I didnt note where the needles were,last time I had it running the idle jet was 21/2 turns out and the main 11/4 turns out,I have set these to 11/2 turns on the idle jet and 2 turns out on the main ready for my try with nitro tommorow,the oil content in the 5% fuel is 18 % klotz oil,Im confident that there is no grit in the fuel system.

I am glad to see you re-set the needles. Getting a reliable idle will help your tuning and midrange funtion.

Is your 32F-H ringed or abc (really abn)?

What plug are you using?

does anyone know where the idle needle would be factory set,there is no info on o.s. site as this engine uses the 3h carb,tried the blowing through the jet until i can hear my breath and that but it didnt seem to work,unless it was a fuel problem then

Since it is ringed you can run it a bit richer on the high end. BTW - how much time was on the engine before you re-activated it?

Setting the low end will take some trial and error as you've no manual to refer to but I would estimate starting the engine with the low end out 1 1/2 turns
and the high end open 1 3/4 turns. Get the low end dialed in first then the top end then go back and check the low end.
