gets warm then runs rough as old boots???????

[bakedbeancoloureddolly]

when i first start up the old beauty she runs lovely fires up straight away and revs nicely drives good too but if ive been drivng for more than about say half an hour and its got nice and warm it starts running a bit...........dunno how to describe it just runs rough would it be the timing ive timed it up and it seems to run ok as i said to begin with but i dont know what this one is.................also when i put my foot on the clutch i lose about 500 rpm any idea what that is................oh the joys of owning a dolly!!!!!!!!!!!!

How do you manage to lose 500rpm my pressing the clutch?! When does this happen?

[bakedbeancoloureddolly]

happens all the time dunno why. at the moment its revs a bit high as i havent had time to set it so at the mo it sits at about 12/1300 rpm i know its way too high but i finish work late and cant be arsed when i get home so when i put my foot on the clutch i goes down to about 800 rpm and i really dont know why

[2F45T4U]

All the time, even when the cars not moving but in gear and when your doing about 70 on the motor way


You mean out of gear sitting still, You push the pedal down and it slows the engine down from 1200 rpm to 800rpm? Eeeeekkk. Really buggerd clutch/release bearing?

[bakedbeancoloureddolly]

yes when imnot driving but sat still oh bugger i didi hear the release bearing a bit the other day and it does slightly grind every now and then oh well more money to throw at it

[2F45T4U]

What engine is it?

[Dollyboy]

see my response to rich's 'air box pipe' thread, could be a possible answer in there somewhere...

[barracuda816]

Do you have waxstat jets? it definatly sounds like a fueling fault, after a nice long run when warm take the plugs out and have a look what colour they are. also do you have to start her with the choke? finaly if you pull the choke out when warm does it get better or worse, if anything?

[Jon Tilson]

Rough running when hot ubnder bonnet us waxstats leaning mxture too much.
Check for good heat shield...essential on ohv cars, which also do need the cold air inlet too. Also breather pipes...

500 rpm drop on clutch eh? Sounds dire...

knackered release bearing is your best case....worn thrust washers and damaged crank your worst...

i'd go for crank thrusts check the end float out think if a clutch was bad enough to drop the rpm that much there be a lot noises

[Jod Clark]

Thrust washers for certain. Fix this as a matter of extreme urgency. If you continue to run with it like this you'll scrap your engine. Just pray that they haven't already dropped-out. PM me if you need help / advice.

been a long time since i replied sorry well the engine is a 1500 tc when it does get warm yes it gets better when you pull the choke out i have also noticed that once it is warm you can hear the release bearing whiring so i think it is that but this is all academic at the moment as i blew the gasket to bits on christmas eve going to get a new xmas tree and the car is in my garage with no head as it was warped and is in a garage already skimme dbut i cant get to it as there shut till after the new year. oh well.

[Lewis]

Isn't it a bit pointless getting the head sorted if the bottom end is most likely fubared?

I'd just get a decent replacement lump, or get it all sorted in one fell swoop otherwise it'll be coming apart again.

[Jod Clark]

What you'll be needing is a Jod Clark short engine to go under your shiny new head. you know it makes sense, and if you've already stripped the head off you won't need a crane to change the lump over.

Lovely jubbly
