HPI RS4 engine
Hello,
I was given a HPI RS4 2nd hand from my bro who lost interest. I know the car sat in a gargage drawer for over a year or 2. I started to break down the RS4 for a good cleaning, but noticed the main purple gear doesn't turn (refer to pic), and crank cord won't budge. Any suggestions? Could the engine be locked up?(is that even possible)
Please be patient as I'm a complete newb to the RC scene.
Thank you

The basics of trying to run an engine that has not been in use for years would be throw out the old gas and change the fuel line.

One more thing when your done using it throw away the gas.

Remove glow plug,see where piston froze, if at or near tdc, last time it ran it was not stored a bdc. Use ARO , LET IT SOAK 30min. Use pair of channel lock, grab around the flywheel, and turn the opposite direction the pull srart. This will not put so much stress on connecting rod and bearing. Once it breaks loose you can probably use you pull start. Then you can decide what you want to do.

engine will be just fine unless there is internal damage. A buddy of mine has a .40 os airplane engine sit for 10 years and was all seized up. We took CRC spray lube or wd-40 and got the engine to free up and we took it all apart and cleaned everything with wd-40 piston rod sleeve crankcase crank. It had some rust on the components and we just cleaned it up. polished everything up and got the engine running. we preformed a breaking for the engine to make sure the engine was ok and just make sure everything was seated in. Then we flew the plane. He put about 2 1/2 gallons threw it before the plane crashed.
unless there is physical damage to the internal engine components don't worry just clean the entire engine up and start it up.

I still have one of these, was my first r/c car ever, bought it in 1997 with the HPI .15FE Nitro Fail...
I ended up putting a .12cvrx OS engine in it which was a smaller engine and ripped a whole mess harder than the .15...
I haven't ran it in 10 years though.
the kit itself was nice, needed all the upgrades like two speed and everything. Let me know if you need any help with the car, I know it inside and out.
