Piper Posted February 4, 2018 Report Share Posted February 4, 2018 Hi all, I'm a new Spitfire owner. I bought the MK4 last year and have been taking it out every 2-4 weeks in the winter months when the weather permits. Although the car runs great it can tough to start after sitting in a cold garage for 3 weeks. I was thinking of boosting with with some starter spray. Do people recommend taking the air filters off and spraying directly into the carbs, or just spraying into the air filters? Thanks Link to comment Share on other sites More sharing options...
Paul H Posted February 4, 2018 Report Share Posted February 4, 2018 I have similar issues especially when low temps. I use carb spray direct into filter intake . A quick spray in each intake . Paul Link to comment Share on other sites More sharing options...
dougbgt6 Posted February 4, 2018 Report Share Posted February 4, 2018 Do what works! However, you may be suffering from drain back, where fuel drains back to the tank. Does your fuel pump have a primer lever? If so give this a few.... well half dozen pumps before firing up.. If no primer might be worth a refurb kit for the pump.

Pete Lewis Posted February 4, 2018 Report Share Posted February 4, 2018 If the fuel pump has a hand prime lever , give it some pumps to top up the float chambers Make sure when you pull the choke that the jet holders actually drop fully , and return fully when control is pressed back in. What spark plugs /type are fitted ?? The mk IV Will have a ballasted 6v coil as std. This needs a 12v feed when you crank it can you make sure you are getting a full 12volts when cranking . Are there any modifications from normal ?? They dont need starting sprays , only as a last attempt, it should have no problems starting Apart from evaporation lowering the float levels when left for long periods Pete Link to comment Share on other sites More sharing options...

68vitesse Posted February 4, 2018 Report Share Posted February 4, 2018 Find the best way with my Vitesse is to turn it over on full choke leave it for a few minutes then it usually starts easily. Just like me it does not like being rushed first thing. Regards Paul Link to comment Share on other sites More sharing options...
Piper Posted February 4, 2018 Author Report Share Posted February 4, 2018 Thanks all! Much appreciated. I'm sure that more than anything it's about me getting used to the car. But all the above suggestions are a great help to point me in the right direction. Thanks. Link to comment Share on other sites More sharing options...
Qu1ckn1ck Posted February 5, 2018 Report Share Posted February 5, 2018 I have similar problems on my GT6 and priming the pump first has certainly improved starting after a spell sitting unused. Link to comment Share on other sites More sharing options...
