|Thread: ASP 80 AR 4 stroke|
After re-fitting the fuel tank and connecting new fuel pipe. Connecting the Carb and Exhaust only to the fuel tank I left the crank case breather feedingout of the bottom as sugested, thanks for spotting that out.
I noticed that the glow plug fitted was not glowing when test out of the model although it was taking current . The only glow plug at the local model shop was anoter Taylor A long reach glow plug for 4 stroke engines. I tested the new glow plug which glowed as you would expect.
When the new plug was fitted this changed everything. It coughed, splittered and with some help on the throttle from my 4 year old son it was trying to run but wasn't not quite there, I adjusted the second screw for idle and screwing this in quite far, it sprung into life. A tweak on the Main mixture screw I'd say it was roughly around the 1 1/2 to 2 turns out not sure exactly, it runs perfect on 13 x 8 prop on idle and powerful with throttle up.
So, all worked out with a working glow plug and connecting the fuel tank to the engine correctly and getting the mixture right.

|Thread: ASP 80 AR 4 stroke|
When I read the manual for the SC engine that came with the engine the running in mixture states to be 5 turns out on first time running !
Steve, when upside down I turn over the engine by hand and I hear no fluid at first and then the second turn some fluid is then heard through the engine, and only after doing this turned the right way after does the engine run as if normal up to 1/2 throttle until it cuts out .... I can confirm the clunk tube within the tank is connected to the carb and the two tubes at the top of the tank are connected to the crank and the other to the exhaust.
I wreckon new tubing and an OS glow plug will be a good start towards the problem. Will get it done at the weekend.
Hi to Ultimate, I fancy the idea of an onboard glow setups where did you get your Timbo's onboard glow setups from ?
The fuel tank is going to be re-fitted into the fuselage and dropped down 5mm however I dont think the position was causing any problems, I'll fit new pipes external and internal of the tank. Clunk tube is free but I'll change the tube and check again. My nitro is %10. I'll get an OS plug if it will help. I'll adjust the mixtue to 2 turns I want it a little rich while running in.
Thanks, let you all know how it goes!
I have a new ASP 80 AR 4 stroke which I am having trouble to get it started.
It is fitted into a model already in the hope to run it in on the model, this is fitted with the head facing down. Wish I had done it on a bench now!
The mixture needle is about 4 to 5 turns screwed out from being all the way screwed in and the idle screw is about 3 to 4 turns out.
If I put the model upside down and turn the prop a couple of times I hear the fuel through the engine I guess it is entering through the crank case nossle I turn it back the right way and it starts up running at about 1/4 throttle and moving it to 1/2 throttle is ok for about 3-4 seconds before it cuts out. any more that 1/2 throttle cuts out.
I first thought it was the fuel tank position being abit to high in relation to the carb but I have put it on the side of the body it is in line with the carb with a rubber band.
I have an A Taylor Made glow plug as recommended by the model shop and it is a long reach in comparison to the 2 stoke glow plugs I have that are short reach. I'll try changing the plug but its the same make and type as I bought 2 as once for spare.
Any ideas please of anything to try is welcome!
