Paul Thompson Posted February 4, 2007 Share Posted February 4, 2007 To the font of knowledge that is Blatchat. What do you think is the best starting procedure from cold for a preXflow with 40 DCOEs. I keep flooding it! Link to comment Share on other sites More sharing options...
Pierson Posted February 4, 2007 Share Posted February 4, 2007 I'll start by saying that I don't know the basic differences between a Pre-XFlow and a XFlow, but the procedure for starting my 1800cc X/F on twin 40's from cold is: Elecric pump on (mine's seperately switched - yours may simply go through the ignition) Wait for the pump to settle to a steady beat 10-12 full depressions of the throttle Stay off the pedal and turn over the engine Mine will fire first time like this - then catch the engine on the throttle and hold it at c.1,200-1,500rpm whilst warming (no choke on my carbs.) Don't know if this will work for you but might be worth giving a try. Good luck! Pierson Link to comment Share on other sites More sharing options...

Graham Perry Posted February 4, 2007 Share Posted February 4, 2007 Paul, does it have a proper choke ? I remember some pre-crossflows had the choke mechnism activated on Weber 40's. If so, don't use it and only pump the throttle a few times instead. The number of pumps needed is the bit you need to experiment with Link to comment Share on other sites More sharing options...

alextangent Posted February 4, 2007 Share Posted February 4, 2007 Ah, the joys of a Ford. Mine's an xflow, but the principle should be the same, as it's over stimulating the carbs that cause the flooding. Starting an xflow is a very personal thing; everyone's got a different technique, but most include a little pedal pumping while making sure you don't flood the blighter. If you've no electric pump, this technique has worked for every xflow Ford I've had, including the seven; 1. Check you have petrol 2. Turn the engine over, for no more than a few seconds, but don't depress loud pedal. Primes the carb float chambers with petrol. 3. Quickly pump the loud pedal 3 or 4 times; squirts neat petrol into the intake. 4. Crank with foot OFF the loud pedal for a second, then lightly press to 1/3-1/2 throttle (don't stamp on it, that just squirts lots more fuel), keep cranking for a second or two. It'll should start to catch & fire on 4. Gently blip the pedal as it catches, and hold the revs up. If it doesn't fire, leave it a bit and start from 4 again. Otherwise you'll flood it.

se7enmad Posted February 4, 2007 Share Posted February 4, 2007 10-12 full depressions of the throttle erm, easy to flood carbs like that! 😳 try a couple of blips of throttle, then start by flooring throttle (no stamping and no nothing) as you crank it, easing off to keep engine around 1200rpm Are the carbs jetted correctly?

Pierson Posted February 4, 2007 Share Posted February 4, 2007 10-12 full depressions of the throttle erm, easy to flood carbs like that! 😳 As has been said above, each to their own, I guess - this works for my engine and ensures a consistent method of starting. Any less and my carbs simply don't get enough fuel to allow the engine to fire, let alone flood. Pierson Link to comment Share on other sites More sharing options...

deanteam Posted February 5, 2007 Share Posted February 5, 2007 Mechnical or electric fuel pump? Either way depending on how long the car has stood the float chambers have to be filled, obvious really but can be quite a time with mechanical and of course weakens the battery. If mechnical no need to pump the throttle better to keep foot off. Once you have weighed up how much you need for filling the chambers stop turning the engine, unfortunately this can only be down to experience. If electrical wait till pump changes note. Then 2 or 3 pumps and then take your foot off the throttle. Try starting with foot off throttle and only press down once engine is turning well or catches.

Paul Thompson Posted February 6, 2007 Author Share Posted February 6, 2007 Thanks Guys as ever a great deal of info. Looks like I am too impatient. Your right Geoff Honda's are much less troublesome. Link to comment Share on other sites More sharing options...
Sheds Moderator Posted February 6, 2007 Share Posted February 6, 2007 If you flood it the cure is to push the pedal slowly to the floor and crank the engine for a few seconds. This ensures maximium airflow though the carb without excess fuel from pumping the accelerator and so dries the engine out, allowing it to start.

elie boone Posted February 6, 2007 Share Posted February 6, 2007 Plugs that have been foulled really need to be replaced, they mostly are the cause of rough running and difficulty to start the engine. X-flows, once they know you and you know them its a piece of cake 😬 Link to comment Share on other sites More sharing options...
Whiz-kid Posted February 6, 2007 Share Posted February 6, 2007 Paul, I have similar challenges with my VX1.6. During the summer when I use it once a week, 4 presses of the throttle, turn it over and it fires on the button. If I don't use is for a month or two during the winter months, it seems considerably more tricky to catch and keep ticking over. Usually takes 4 or 5 attempts to nurse it into life. I'm thankful I have a battery conditioner to give the amps to turn it over a few times. Link to comment Share on other sites More sharing options...
andy couchman Posted February 7, 2007 Share Posted February 7, 2007 Pop the plugs under the grille or heat up with a blowlamp and she should start easier. Always have a spare set of plugs. If flooded take all plugs out and turn engine over on the starter to get rid of vapour in the cylinders. Cross fingers. Pray. Andy Link to comment Share on other sites More sharing options...
