4000 rpm and out :(
karlak - 31/10/09 at 05:05 PM

I have a 2.0 Pinto in the MK, a standard engine (I believe), a 32/36 DGAV carb, along with a pretty standard exhaust and manifold.

The probelm is that when getting a move on, the car seems to hit a 4000rpm limit, a little stutter/pop from the exhaust and that is it.

It is OK in 1st and 2nd gear, but only seems to happen in 3rd and higher. Obviously this makes overtaking a little hairy - to say the least .


Any ideas as to what the problem may be? Does anyone know where I could take it in the Bedfordshire area for it to be looked at / tuned ?

Check the fuel flow rate to the float chamber & clean the main jets.

Is it distibutor based it could be the condensor breaking down I had this problem years back with capri's and cortinas running the pinto engine also points slipping if its an old pinto

Yes, it is distributor based. I am not at all mechanically minded, but was curious why it seems to do it in the higher gears, and not the lower ones ?

dwell angle, timing setting, carbs settings any one or all of them will cause it to run flat higher up the gears as will a fuel pump thats not working to full capacity i had this on my 1st car it worked fine untill it was loaded up then it could not supply enough fuel

I had a Citroen AX some years back. It maxed at 40 mph independent of which gear was selected.
Turned out to be HT leads.

Condensor breaking down or points gap to wide, let us know what it was when you solve t.

I will need to take a look at all the suggestions above. Either that or take it to an expert as I am on a real steep learning curve here .

Does the Haynes Sierra manual help out with alot of these tasks ?
