help with my Aircooled engine

[anglais]

Hi

just fixed up my type t25 and got it through its MOT but i need help tuneing the engine,

its a 2.00 litre Aircooled with dual webers 34ict, the engine is only about 5 years old,

i have put new plugs, points, cap roter arm, and attmepted to time the engine, but when running its pops allot has a lack of power you have to pump the fuel pedal to get it going and it will only cruise around 50mph,

Im sure its the webers that need sorting is there anyone near York who can help, im happy to pay just need to get this sorted so i can sell, my wife wants a high top to fit the kids in better

Thanks

you could help by putting your location in your profile... for future reference

Best and most easiest way is a rolling road fettle.
try the yellow pages first or try googling rolling road tuning, Yorkshire.

is your engine a CU and have you timed it before top dead centre sounds like its to advanced
should be 4-5 after top dead centre.
also your carbs have a lot of vacumn pipes and balancing pipes that can let air pass so they need checking over.
I generally set the carbs up with a pair of vacumn gauges so as to balance them and then run through on an o2 meter for co2% which should on a well set up CU be about 3.5% +- 1
have you checked that the choke flaps are operational aswell othewise you will be tuning from the worst start poss.

What dizzy does it have?? if std dizzy and vacs are not connected then 5deg ATDC wont be right.. If itsan "009", then it wont be right either and they bring a whole set of other issues..

Could be the main jets are not big enough too...

[albertramsbottom]

If its a CU, then leave all the vacs connected and disconnect the idle stableisation unit and plug the two plugs together and time for 5ATDC.

Becuase im no expert

if your cu engine has the old points dizzy from a bay 2ltr CJ code dizzy number 021 905 205P time it at 7.5 btdc.

Cheers for the response

its a cu/cv 2.0 t2 es150 is what it says on the engines recipt, standard dizzy with points, to be honest timing i strugled with, getting the engine going was well beyond anything i have done before . was hoping there might be soneone with more experiance near York to have a look

Could be the jets but i havnt changed them since i got it , i presume at one point it was running right , previous owner spent a fortune on it! to do the timing i had to borrow equipment to get it done, i thought there could be an air leak sonewhere becasue of the popping but havnt found one. pumping the throttle to get it going was a new one to me, its an automatic could this affect this

correct timing for a standard CU

This will only work if you have the original standard electronic dizzy fitted. i notice in your post you have one with points fitted.

[toomanytoys]

Points dizzy is prob not standard and may well be an "009"...

Pic please??

[woodmonkey]

i got a dizzy with points, it really doesn't like it if they are not set just right, pops splutters etc oh and keep a couple of spare sets they don't last long!!!!!!

[anglais]

hope the pic works

looks like you have the dizzy from a bay window 2ltr engine code CJ fitted. you can check the points with a dwell meter should read 50+ or -2 then if you dont have a strobe timing light you can static time it at 7.5 btdc , best to borrow a strobe to check the full advance though.
