Default Pull start loose "slipping"

More problems ...

When i crank my pull start its almost loose .... im able to start the engine but it was a lot harder to pull before , sometime when i pull i feel the piston is not moving at all ..... once it started engine seems to run well this all stared when i finished my gallon of fuel ( o'donnell 20%) and now using blue thunder sport 20% maybe just a coincidence i dont know

Im new to RC cars ... but really addicted , i have a 777 kyosho with star K4.6 nitro engine

It's a one way bearing in a hex nut. Basically a roller bearing cam, and I suggest you remove the engine, and then remove the scews/bolts that attach the the pullstart.

Then clean the one way bearing with WD40 and then put a clean rag throught it and turn to really clean the roller bearings. We use a special "one way" lube, it's a very thin but not OILY lube and unless u can get some, the WD40 and then cleaning off the residue should do the trick.

While you are at it, clean the shaft that connects to the engine's crank and if you are really keen, you could remove you clutch and give your engine a good clean too.

I would also take the opportunity to clean the engine's outer with a degreaser, just be sure to block off the air intake and fuel nipple.
