retro cars feature!

another idea that was flung my way is the carbs! are they mounted correctly? if webbers are too tight and not fitted with the correct rubber seals and washers that allow them to move that can do some very strange things all due to the vibration of the engine! aparantly at certain revs it can start t...

have you checked the poundage of the valve springs??? or fitted a new set?? or checked that your current ones are fitted corectly and are compatible with the rev range the cam is trying to pull?? it sounds a little like valve bounce in those second pair of videos!! im going against the engine builde...

my thinking was a basic way to dyno the car and setup the carbs too! ok it wont give u a bhp but evrything but

now having the ability to show you when you are running lean would be a good one maybe another gauge for the tuning window! especially for the turbo guys! and if there was maybe a rev limit cut in when things got dangerous it save a piston or two!!!

im an essex lad and i do sympathise with those who are in the floods at the moment as i can well imagina the chaos and upset it would cause. but at the same time i cant help but see pictures of flooded land for miles around except for a church on a hill that is still bone dry and ho an island!! make...

i wonder if the pin 11 output taken thru the older smiths inductive pickup tacho then to earth via a condensor would work! anyone got one to try it with?

jsut spoken to a friend that builds engines and he rekons cam timing too!

it would stil be well worth doing a compression check! you could be sharing compression between the 2 cylinders that are giving you a problem!

well spotted about the mini forum, yes im fikus jsut about everywhere! im afraid i cant comment for sure about the VR sensors! IIRC you can spin the engine over and measure the voltage coming out of the sensor unplugged! or someting like that!

hi, i dont know if im right at all with this but i didnt think ford used magnetti marelli vr sensors!! that sounds more peugeot/french! that could be the problem if its not a ford item!!

just a thought u can get blow back jsut at certain revs because of the pulsing effect of air getting drawn into a carb, it wud take me a long while to describe it so look a little into pressure waves and induction length tuning. this could be the problem! failing that it could be a fuelling problem,...

if you're going non edis then maybe a different or selectable type of trigger could be employed. maybe utilising static timing from a distributor! i know there can be an amount of slack in an ignition system with a dizzy because of slack in the timing chain or work gears etc etc, especiall on a-seri...

sorry for bad spelling, remember recently a thread about using the vacuum readings from webber carb fitted engines or those with lumpy cams, i said that rover fitted a ball to act as a reservoire for map readings on the exige because of fitting the engines with throttle bodies. well i stumbled acros...
