Engine problems

[Jim (across the pond) Adamek]

This looks like a great site. I am having a problem. The engine is out of a Hillman Hunter. The engine idles just fine but when the gas pedal is pressed the engine dies.  I replaced the fuel pump but it did not help. I took the top off of the carb but it looks just fine. Any suggestions?

Perhaps it was a dirt particle which is now dislodged. It might be worth cleaning out the carburettor and seeing if there is any evidence of bits getting into the carb, rust from the fuel tank would be a good contender. If so, an inline fuel filter ought to stop that causing problems.

Alternatively, could it be water? Modern fuels contain more ethanol and I think that can absorb moisture. Whether it can separate out or not I cannot remember but it might be affected by a change in ambient conditions.

I have an inline fuel filter in line near the fuel tank so sediment in the carb should not be an issue. For now I have the tools in the old girl just incase she dies again and hopefully I can once again run the car on ldle and drive it home at idle speed. I am thinking I should get a carb rebuild kit just incase I need it. For a Hunter I doubt there are any kits over here. also when looking for a rebuild kit the ports come in two different sizes and I believe I'll have to break down the carb to get the proper size unless someone knows the port sizes for a Hillman Hunter

Jet size is 90, needle is either a 5M or 6R  but some later ones  were fitted with a 100 jet, but needle size is the same  thats for the 1750 , so as both are listed, you should be ok using either,  i hope this helps

I did put on a new fuel filter. I am also thinking that when I put the oil in the top of the carb maybe it took  some time to work its way in to lubricate to carb and that it just happened to be the time when I got it to work. The carb was totally out of oil when I found the problem.

I am going to take a ride in it today. Hopefully the old girl is done messing with me.

Well I took her out to the grocery store today and she ran just fine. It's kind of disconcerting not knowing what exactly the problem was. I want to thank you guys for all the information you supplied.

Yes, it is irritating when you don't know what was wrong as you can never be sure that it is not going to come back again. It is much better if you think that you know what you did. Still, it is nice to be able to enjoy it again.

I have had the old girl 9 years and this is the first time I have really had a problem so I can't complain.
