metal mickey Posted February 17, 2001 Share Posted February 17, 2001 Hi Everbody, Started the 7 this morning after 4/5 weeks of it not running. The engine (zetec) started easily and idle's well but does not want to rev up quickly - the engine revs then tries to die off! If i build the revs up gradually all seems to be fine, I suspect a fuel problem and have checked the fuel pump and filter and they seem fine. The cars running on 45 webers, anyone got any ideas? Thanks. Link to comment Share on other sites More sharing options...
CHRIS CLARK Posted February 17, 2001 Share Posted February 17, 2001 Had a similar problem with the outboard on my ski boat. It was sticky floats/needles in the chambers, but I would have thought that after 5/6 weeks yours shouldn't do that! Mine had been drained for the winter and still there was enough residue to create a problem. It does sound very fuel related. If all the temp and pressures look good, can't you just leave it to idle and see if the heat warms/dries/unsticks something ? Doesn't sound very technical does it, but it may have the desired effect. The moral of the story is:- Use the car more often!(Or at least run 'er up) I've known clutches seize in less time in this damp/crappy weather.

John E Posted February 17, 2001 Share Posted February 17, 2001 Was that because it was a two stroke and all of the fuel had evaporated. Common issue with outboards that do not have oil injection. There must be something else on the Zetec. Maybe a sticking throttle linkage. This can be caused with water ingress into the cable. A good dosing with WD40 is called for.

CHRIS CLARK Posted February 17, 2001 Share Posted February 17, 2001 John E. Nothing as crude as petroil lubrication! This has a fully metered oil supply with induction/throttle sensing etc etc.As stated, the fuel had been drained for the winter (from each carb [3]), but the things still got stuck!!!

Swiss_Tony Posted February 18, 2001 Share Posted February 18, 2001 Sounds like it may be the accelarator pump on the carbs not pumping fuel. If you remove the air filters and pump the throttle you should see fuel pumped out from the middle of the carbs. (assuming the float chambers are full). Each choke should do this. This could be the jets blocked. It may also be the float stuck on one carb. It could also be ignition related but less likely.(ht leads etc) Good luck James Link to comment Share on other sites More sharing options...
metal mickey Posted February 18, 2001 Author Share Posted February 18, 2001 Thanks everbody,I'll look to see if the carbs are pumping fuel as they should. What I can't understand is why the engine will rev up happily if I build the revs up slowly but not if I do it quickly. Does anyone have any other ideas? Thanks.
