How ya going guys,

 

ive got a 84 rolla S and its been running like dream ever since ive got it a month or 2 ago, now the carbie is playing up. I pull the choke all the way out it turns over alright i give it a bit of time to warm up a bit, then i press the choke in 1 click and the revs flaten out and still runs fine then when it warms up to the 1st marker on the temp guage then i take the choke off and it stalls without a second thought. when i give the car some revs it dosnt stall but as soon as i take my foot off the accelerator it dies so I'm assuming its an idle issue.

 

i checked the coolent, dunno what posessed me to do it and its a milky colour and it smells bad. i did a bit of poking around and it could be exhause gases or dare i say it a head gaskit issue.

 

any thoughts anyone?

 

thanks for the help guys,

Matt

Yep, gasket is gone, Whip the head off, Get it skimmed, New gasket and whack it back on.

 

Des :jamie:

that would be bloody right, funny thing though i was talking to a mate the other day because i was looking for an excuse to buy a new motor for it lol.

 

what could have caused this? could it be the fuel i use?... do the rollas need a lead replacement additive? because i filled up with regular unleded before this started to happen?

 

cheers,

Whip the head off, could be just a head gasket. Get the head looked at while it's off. If the head is knackd, the rest of the engine probably isn't far behind. If head is still fine, bolt back on and drive off.

It could have been caused by a number of things but most likely just age got to it. Have a look at the gasket when you pull the head off and see if there are any sign of detonation just to be safe. But i'd say it will be fine with a fresh gasket and head skim.

And no, you don't need lead additive.
