she runs................again

[baz105e]

well after killing my first engine on its first outing at cf show (before i even got on the strip) i popped down to see a certain mr jenkins who had an engine sat around which he very kindly donated to the cause (thanks again kev ) so after a couple of days and 12 cans of redbull the new engine is in and running . i only have one problem and thats when i open the throttle it will hesitate slightly (asif it has no spark) before revving up. i have a vaccumm guage on the dash and if i open the throttle slowly and keep the guage between 20 and 25 hg the revs will build with no hessitation but if i open the throttle fast it will hessitate. you can see this on the vid.

 

any ideas?

 

oh and the exhaust isnt staying like that its just a silencer welded onto the end of my side exit to keep the neighbours happy

[BaileyMex]

could it be fueling?

[baz105e]

well i dont think so as i've just put a 125 psi fuel pump on and im getting a strong ammount of fuel back through the return, there is also a regulator built into the fuel rail

[BaileyMex]

I had similar problems a few years ago and traced it to a poor earth on the facel fuel pump i'd just fitted.

[baz105e]

ok i'll check all of my connections again just incase the earth on the fuel pump is a little poor anyway i'll make a proper earth with a nice thick wire

Nice one m8

see what it's like after you've run it around for a bit

if you've got a pressure gauge check the fuel pressure.

 

p.s. Kieran is driving me mad!

[baz105e]

pmsl kev, i'm going to run it for an hour or so later in the week (dads on nights) it did it with the old engine too, well when i first ran it it was fine then when i got it to pod it started doing it

 

and i apologise for any nagging caused

 

i dont have a fuel pressure guage so i dont know how im going to check fuel pressure

[baz105e]

i've just had a brain fart !!! when i took the engine out i bent the copper fuel pipe a bit i think i may've kinked it reducing the pressure. well thats another job on my TO DO list

think i just needed a little mental inspiration cheers guys

[KJ 1320]

I've got fuel injection pressure testing stuff m8,I'll bring it up with me when we come up,as soon as I have another day off
