    The air-gap is CRITICAL when you set these EI modules up.
    Did you check the timing after installation ?
    Might need tweaking by the sound of it........

    I used the plastic feeler gage to set the gap and did reset the timing. Maybe I'll do it all again tomorrow.

    Was this in the 1700?

    If so, how did you set your timing?

    This was my 1500 type 1 engine. I removed the spacer plate and reset the air gap and timing and it seems to be all good now. Although I was hoping for a little more power. But it is very smooth now. And no backfiring!

    Hi all, me again;)
    So I checked my timing (1500 type 1) with a strobe light for the first time yesterday and while my kombi has been running well (all though with a bit of run on occasionally) the timing was quite advanced. Around 25 - 30 degrees. I adjusted it back to 0 degrees TDC as I have always had it while running points and condenser and it ran like crap again! No power and lots of backfires. I then set it to 10deg BTDC and it was better but still backfiring a little and less power. So it seems now that I have the electronic ignitor it will only run well with full power if it's at around 25-30 deg BTDC. Is this normal?

    Cheers,
    Scott

    just borrowed one to check vac adv on the lpg

    flame thrower D1865

    owner took it out as it ran crap and not enough advance

    I put it in the peril and checked curve . slow to initiate and jerky . limited mech adv and only occasional vac.

    difficult to predct when driving.
    put old 009 back and much smoother.

    dissasembled and vac doesnt work on mouth suction and very stiff by hand.
    springs look out of wack as well compared to others i have and matches observed advance .

    going to have a play to smooth action and new springs.
    chasing a suitable new can or a known to check against.

    all just for the hell of it as need a couple of decent svda regraphed to suit LPG and improve economy due to the current prices.

    I think Barry was probably refering to the higher advance of 30deg.

    Whats number on dissy?

    was it running ok before you installed the igniter?

    american but gives some idea. Im sure Andrew will give details for the 1500 donk

    http://www.oldvolkshome.com/ignition.htm


    Distributor: VW 131-905-205, Bosch 0231 137 011 > 315-905-205B, 0231 137 031
    Can Use: VW 113-905-205K/L, Bosch 0231 137 009/010, 113-905-205M, 0231 137 021, 113-905-205T, 0231 137 035 or 036

    Timing Set At:: 7.5deg BTDC Static or @ 800-950rpm w/strobe and vacuum hose disconnected and plugged
    Advance/Retard Range: Vacuum (Advance Only): 17-19deg @ 1.3 In. Hg, 24-28deg @ 3.2 In. Hg

    should have some mechanical advance numbers and then the vac so you can check curve without vac .

    Ill sniff around.

    113 905 205 M. Ah, so I might be ok in the advance range then?
    Ahh!!! I didn't disconnect the vac hose!
    Was running fine before but wasn't and still isn't idling the best when cold.
    Thanks guys.

    Any more thoughts on this? I timed it at idle again with the vac hose disconnected and it didint make much difference. Still runs best at around 25-30 degBTDC, but still get run on every now and then.

    Check your ignition leads are in the correct order. should be

    3-2
    4-1

    On dissy cap when looking from rear engine lid.

    That distributor needs to be timed to 0 or TDC with the vacuum disconnected from the carb at idle. Carb should be a 30pict2 single port.

    That distributor is vacuum only and should provide around a total of 30 degrees advance.

    Yep, leads are all where they should be. Has only been a problem since the EI went in. Used to always time in to 0TDC and was fine. Everything I read said that changing to EI is an simple effective improvement so I'm not sure why it's causing me grief. I mean, the bus runs well etc but it can't be good if it's not timed correctly. I haven't taken it on a highway drive yet, who knows what might happen. Thinking about going back to point and condensor. Pretty annoying though!

    When you put the EI in did you pull the dizzy out. If so did you put it back in correctly.
