no body got any i thoughts ?

with the engine running pull one plug lead off at a time to find which cylinder is missing that will help narrow down the search, if everything else looks good might be a sticky valve.

done lead test 1 and 2 but good spark and compression take it down road ok then dies as though running out of prtrol but petrol getting to carbs

all gaskets and jets ,seals in carbs .. i had simmiler problem but mine is on a 32/36 carb and it turned out the be the power valve gasket was split (and it was brand new about 6 months before hand ) so changed that and its been fine ever since , sounds like carb problem to me as you have changed all the other problem areas

rs clint

stripped the carbs all in good condition diaphragms good no blocked jets

matthewpickup

hmm fuel regulator ? i am not 100% sure of the bike carb set up on the pinto tbh .. was it running fine before or is it a new set up?

camshaft lobe worn?

new cam about six months ago car only done a few hundred miles since rebuild been set up with carbs for over a year no probs completely stuck as is the garage

matthewpickup

as i said i dont know a great deal about the bike carb pinto set up , do you have to re jet the carbs ? and are you running the same regulator the bike would run ? and dose the misfire happen when you just rev the engine ie standing rev not driving ? and i am guessing its new fuel?

blocked filter in tank? has sludge in mine, Ran & revved fine but would die on the road..

Swap the coil, when old oil filled type warm up they lose energy output , get a gpa coil off here, 2.5 times the voltage output....

thanks for your great feedback appreciate it cheers

rs clint

still no joy since changed module coil had carbs checked and professionally cleaned compresion and spark good petrol getting to carbs ok misfires bad then dies timing is ok real mystery well stuck anyone had these probs

gjh

Jesus!! Thinks its time it went to a specialist. Sounds like a nightmare.

Have you tried points and condenser ,is it a new dizzy as these crack

It could be that the dizzy is to advanced or not enough have you tried turning it by undoing the 13 mm bolt the bracket and turn the whole thing !!!!

rs clint

electronic dizzy ,yeah m8 advanced timing still no good bran new dizzy cap ,taken it to two garages ,just guessing what it might be pissing in the wind lol

karl mcghee

Have you had a compression test done !!!

rs clint

yeah m8 compression test done short of taking head off cant think what else to do?

karl mcghee

Just posted on another hopefully a will have something shortly

rs clint

cheers m8 weird one driving great next minute low revs ok then totally misfirihg dying on me changed complete ignition system

karl mcghee

It does all point to blowen head gasket

Wot was the compression on each cylinder should be around 125 bar of pressure per cylinder


Have you changed all ht leads !!!

rs clint

wasnt present whrn done garage done compresion test they said compression was good perhaps e should do another one?

karl mcghee

Are you sure it's a misfire??.... could be an overly rich fuelling!... my pinto is on bike carbs now and it's super smooth apart from a little rich low down to kill a flat spot, if I idle to long I get a stumble as the richness chokes it a bit... have you changed anything in the carbs???

I'm on manual pump with fuel reg too.

not changed anything in the carbs mechanical fuel pump ok, got carbs off now gonna get 38 dgas set up for the pinto ,decided to go for new rather than mess about with second hand stuff take it from there

karl mcghee

OK let us know how you get on

karl mcghee

Hi go it some more info

The problem is the carbs



Most likely the carbs making it run pony.... stripdown in the least.... all needles must have the circlip on the bottom slot, mains should be around 160/170 depending on what carbs they are, start with mixtures 2.5 or 3 turns out from lightly seated.... assuming there is no airbox as such... be careful not to trap the diaphrams when fitting the carbs tops back on and watch out for any little o-rings too, don't let the carbs faze you, imagine they are 1 carb at a time, they will need a balnce too, this can make they run gogga, this can be done by eye with the carbs off, but easier with gauges... if unsure ASK... I've stripped cleaned and setup loads of bike carbs (on bikes).

rs clint

cheers for info m8 the carbs were stripped and cleaned good diaphrams no clips missing on ebay at the mo getting 38 dgas at the weekend keep you posted m8

matthewpickup

problem with carbs is it dose not take much to mess them up ie pin size holes , hope you get this sorted soon

rs clint

after having bike carbs cant bring myself to put single carb back on even a 38 so decided to wait a few more months and get these bad boys much better choice

rs clint

what's people's views on these should go well with the high lift cam

matthewpickup

o very nice
on a full race set up they are around 200bhp (on 48s or 50s), if 40s or 45s 180bhp ish
sound the dogs dangles
just out of intrest what bhp is seen with the bike carbs compared to the twin webbers?

rs clint

dont really know to be honest never had her dynod with bike carbs will probably have to pay a visit to the rolling road let you know what power its making

matthewpickup

that would be good mate

rs clint

just put power spark dizzy on electric fuel pump filter and regulator on just need carbs know unfortunately cant make ford show at santa pod was asked if i wanted to put it on rally stand gutted ,maybe next year
