Bigant Posted May 12, 2012 Share Posted May 12, 2012 Hi After a solid 14 hours trying to get my V8 engine to run smoothly, I am at the point where I need some help! I as hoping to compete tomorrow at Piccadilly Woods with the guys from Mud Monsters but thats not going to hayone ppen as I simply can't get the engine to stop missing? Does anyone know of a V8 carb/emgine specialist in the Surrey area? Cheers Bigant Quote Link to comment Share on other sites More sharing options...

Quagmire Posted May 13, 2012 Share Posted May 13, 2012 I would offer to help but am literally up to my eyeballs in wedding preparations - i've only managed to sneak on here while I eat my shredded wheat Go to Dunsfold? Or is it running so bad that it's undriveable? Quote Link to comment Share on other sites More sharing options...
Bigant Posted May 13, 2012 Author Share Posted May 13, 2012 Hi The engine starts ok, but as soon as you try and rev the engine it stutters and misfires. I am conscious that the lead to plug 7 is a little tight, so I will try and shuffle the leads about to see if that helps. The engine is also lacking any real power, hardly surprising given the way it is running, could it be the carbs? I recently removed both of the "plungers" I simply unscrewed then and them put them back in, could this have caused a problem?

Hybrid_From_Hell Posted May 13, 2012 Share Posted May 13, 2012 Did you refill the dampers on the carbs ? Nige Quote Link to comment Share on other sites More sharing options...
Bigant Posted May 14, 2012 Author Share Posted May 14, 2012 Hi Nige Did I do what? As you can probably tell I am not the most gifted of mechanics! could you expand a little? Bigant Quote Link to comment Share on other sites More sharing options...
Quagmire Posted May 14, 2012 Share Posted May 14, 2012 Tops of the carbs have little plastic things you unscrew and remove- these are the dampers in the dashpots that damp the movement of the piston up and down in the carb body. You need to have clean oil in these or weird things happen, so unscrew a damper, and if no oil then add a little bit (like a teaspoon or two) and re-insert the damper. If you do remove then do not mix them up with each other! Do one side at a time. Quote Link to comment Share on other sites More sharing options...

Bigant Posted May 14, 2012 Author Share Posted May 14, 2012 Hi Thanks for the advice can I just use a standard synthetic oil for petrol engines? I have some mobil 1 knocking around the garage. Is there a mark or indicator that shows how much oil should be added? Cheers Bigant Quote Link to comment Share on other sites More sharing options...

Quagmire Posted May 14, 2012 Share Posted May 14, 2012 I just use bog standard mineral 20/50.... As for how much, its something random like 13ml? Quote Link to comment Share on other sites More sharing options...
Paul Wightman Posted May 20, 2012 Share Posted May 20, 2012 Mr Ant, you can't overfill so pour it in till it overflows, use standard engine oil. 20/50. Not wanting to state the bl**ding obvious, are the plug leads on in the correct firing order? Don't laugh, just check...................

Bigant Posted May 22, 2012 Author Share Posted May 22, 2012 Hi Guys Thanks again for all of the advice, I am away at the moment but will be back at home and on the case this weekend. Cheers Anthony Quote Link to comment Share on other sites More sharing options...
missingsid Posted May 24, 2012 Share Posted May 24, 2012 I am having great fun with mine at the moment, fuel filter problems mean it starts but runs out of fuel as the pump can't deliver enough. This leaves it short of power and stuttering, quick check is to pull on the choke if it speeds up it may well be fuel. Eventually there will not be enough fuel to keep going so it will continue to get worse. Marc. Quote Link to comment Share on other sites More sharing options...
Bigant Posted May 24, 2012 Author Share Posted May 24, 2012 Hi all Cards were pretty dry so I topped themup with oil ss suggested however the problem is still there. Has anyone had any dealings with Challenger 4x4 as far as serving and engine repairs are concerned? Cheers Bigant Quote Link to comment Share on other sites More sharing options...
zoltan Posted May 25, 2012 Share Posted May 25, 2012 Was this engine running nicely and then all of a sudden started to misbehave? As mentioned above, have you checked that the plug leads are correct? Quote Link to comment Share on other sites More sharing options...
zardos Posted May 25, 2012 Share Posted May 25, 2012 Bigant you might want to look at the thread http://forums.lr4x4.com/index.php?showtopic=73238&st=0&p=626061&hl=challenger&fromsearch=1entry626061 Lots of recommendations for Challenger 4x4 Quote Link to comment Share on other sites More sharing options...
