First off I'm Cal, from Queensland AU. I do apologise that my first post is a noob "car won't start" thread, but there you go.
So, I have done a search but didn't come up with too much information. If there's somewhere that covers this topic well please link it and I'll have a read through it to save you retyping and such.
I can't tell you too much about the car's details because I don't know a lot about RC cars and I actually got this one as a gift. Score.
I do know that it is a Chinese branded one.
I have had it running before, but not for long. It got quite hot (melted the plastic cover) and conked out. Nothing was seized or blown, but the car wouldn't restart. I left it sit for a fair while but I've had more time now so I've been playing about with it.
There is discolouration on the (>technical term missing<
) part that joins the engine to the gears that turn the driving gears. So the part with discolouration is joined to the engine.
I seem to be having fuel flow issues. Reading some things I found online and on this forum I've done the following:
Checked glow plug (works, and is a new one anyway; I do have a spare)
Cleaned carb and set to factory (no blockages)
Checked fuel lines (all fine)
Blown through the pressure line attached to the exhaust (pushes fuel through the fuel line when detached from the carb, but doesn't when the fuel line is attached to the carb)
Used the pull start with my finger over the exhaust (this pulls fuel through the system and did give a bark of life but it didn't continue so I'm assuming the fuel isn't flowing under the vacuum of the engine alone)
Checked the exhaust gasket (the gasket between the two halves is fine, the rubber that joins the exhaust to the manifold (correct term for an RC?) is fine, inside the exhaust however there was nothing (struck me as odd, but again I don't know much about RC cars) other than a metal plate with several holes that I assume is a baffle of sorts to help back pressure and noise)
I will mention I did have the cylinder head off (the part the glow plug screws into and is finned to dissipate heat; in case I've got the wrong term); but I screwed it back down as I would on a normal engine, tensioning the bolts quarter turn at a time in diagonal opposites, to ensure a good seal.
Is there a way to check compression on these little cars?
I can feel compression if I put my finger over the plug hole (with the plug out) and I can tell there's compression with my finger over the exhaust; but I don't think there is enough.
Anyway, that's all the information I can think of for now but if I've left something out please let me know and let me know how I can get the information (as I said I don't know much about RCs).
Thanks in advance for any help you guys can give, and again I apologise my first post is a problem one.
