Ok iv got a acme condor that I found in a shed fully built just a few parts missing which are ordered and waiting to arrive. So I put a new glow plug in today poured a little fuel into the carb and went to give it a fire to see what I'm working with. But pull start isn't pull at all really. Feels really stiff. Is it a problem with the engine or pull start?

Sounds like an engine that's gummed up with old fuel. Time for a cleaning.

You mean pull it apart? Piston the lot? Sounds a big job for a newbie haha. You think that would solve it? Or should I stick a new lump in it?
 
Take out the glow plug and drip some fuel in there. Let it sit for a few hours then try to turn the flywheel by hand. Same thing on the low end. Take out the carb and put some fresh fuel in there to help break down the gum.

Iv put fuel in both carb and where the glow plug goes. And I can turn the flywheel by hand
 
Loosen the glow plug and see if it will pull a lot easier. If that's the case, you've got good compression when the plug is in tight.

If I remember right it pulled easily without a plug in it

I have an engine out if a thunder tiger. Do you know if that would fit?
 
Sounds like you have a good engine. Here is what I would do if it were me. I would pull the engine and tear it down. Then I would make sure to have all the bearings removed and just the bare block and crank in hand. I would boil them overnight in some antifreeze ( I use an old pressure cooker for this) while they are "cooking" I would meticulously clean the carb piston rod and sleeve. with everything good and clean I would give everything a rinse off with wd40 and a little fuel. Then reassemble. It sounds like a lot but you would know EXACTLY what you have and that it is clean. Now i also measure and check things but that is just me.
I would not change the engine, do not see the need for it. How does the rest of the car look? You said there were some missing parts. Is there any broken parts? Does it show signs of hard use?
I am the type that every used rc I get I clean the entire thing and check every part. When I get it back together I know what I have and that it should perform just how I expect it should. Dirt in the wrong place can cause a lot of headaches. Take your time and see what you really have there. You will probably end up with an rc that will last you a long time with proper maintenance and care.

Thing is stripping. The engine down to pieces scares. I'm new to the hobby and have just got my head round most mechanics lol. After the engine runs it just needs spur gear but I was thinking about changing the clutch bell to for piece of mind. Because when you roll it, it clangs up like between the 2 cogs it jams
