Chris's Car

About 3 years ago Chris bought a radio control model car from "Extreme hobbies" I think it was called at Indooroopilly Shopping Town. Now vanished and we have no idea what make or model it is.   We have decided to have a go at getting it going.

The problems were and still are
1.  Would not start
2.  Suspect the front problem

So we went to Hobbie One at Creek Road on Thursday.  Arrived there aroud 4:30 and were advised wait till 5pm when Al who turns out to be a bit of a ledgend was due.  About five to four a stream of people arrived carrying cars in various states of disrepair.  These were presumably the true believers who were "in the know".  The cars were lined up on the counter and Al would go from car to car inspecting, advising and dispatching underlings to dig out some spare part or other from "out the back".

We gained some useful information from Al:-
The fuel system is preasurised.  Obvious when you think about it as there is a hose that comes from the exhaust to the top of the fuel tank and blowing in that hose qucikly showed our fuel system was not pressurised.

We purchased a new fuel tank and hoses and an air filter & fuel.  As you can imagine Al is a good salesman.  The fuel tank was too big and eventually I gave up trying to fit it in. 

A search of the internet showed a previously unkonwn (to me) hobby shop on Beudesert Rd.  Went over in the hope of purchasing a new fuel tank.  They had only one and it was $30.  (I think we paid about $8 at Hobbie one).  So gave up on that approach.

 I went back to trying the fix the seal on the old fuel tank.  I thought the seal had dissolved (so did Al).  But upon closer inspection, the seal turned out to be the same milky colour as the rest of the tank.  It was dismantled and cleaned and re assembled and then using the new hoses checked that it pressurised.

So now we had a clean fuel tank that sealed and new hoses.  Later we dismantled and cleaned most of the carburetta.  But it is still difficult to start.  I am not sure if there is more to clean.  I think we are OK compression wise because
a) when it does start it runs
and
b) if we flood it, then you have to take the glow plug out to get it to turn over.

The fuel tank is not original and was ditched before use as it was too big and touched the exhaust and the flywheel (under the pink air filter).

RHS.  You can see the hose going from the muffler to the fuel tank.

Back

Front Diff.
This seems to have problems. 
a) Siezes sometimes (We think) and stalls the engine.
b) One of the wheels seems to free wheel.

(Ignore the half inserted screw.  This is a field fix from last time the car was used.  We replaced this with a M3x8 CSK screw)
