Discovery smokes and apparently gets hot

Ok but that will only adjust off-boost fueling, seeing as its smoking on boost its probably the diaphragm that needs turning back a bit and if you are not sure what you are doing its best not to as it entails taking the top of the pump off

edit sorry just reread your post, you are talking about the main fuel screw right? this ussually has a seal on it anyway

Was lead to believe the screw I mentioned was the one that adjusted the max fuel that'll go in when at full boost (like pulling a trailer uphill in 3rd) which is what made me think that's probably the one to alter slightly (also guessing the cover/collar thingy would've been removed if it had been tweeked). I thought the diaphragm and the screw under the cover were more related to fueling at part or no boost? (correct me if I'm wrong, we're all here to learn).

On the other hand, reading the last couple of posts I'd agree it's probably more wear than anything, pump timing may be worth a look if the owner feels capable enough -as mine smoked a bit when I went a bit too mad trying to get mine spot on :doh:

Wouldn't you have over heating problems all the time if the 'stat was at fault?
