My type 4 engine build...based on AP 1800

  1. Haha yeah that wouldn't help would it. I filled her up yesterday. Although I have to say having an engine that's supposed to fit in a bay in a T25 proves challenging when trying to pull the dipstick :D IF I ever sell this van, it's going to need one very understanding buyer :)

    Good luck tonight. I was in the same position about three years ago. Looking good so far.

  3. Looks like youve used nyloc nuts on the thermostat bracket - not sure but they might over time melt away being right on the engine case - might want to keep an eye on them. Then again may not be a problem...
     
  4. Not to mention the mandatory bum wiggle ;)

  8. Well.....so far we're 50% happy. Cranked it over and over and got oil pressure with no leaks :thumbsup:

    But.....with everything connected it won't start. I knew it would take a while due to no fuel in the carbs, but she won't fire up at all, just keeps turning. I took out plug no 1 and got my 9 year old assistant to crank it, and I get a spark so that's good. But I'm stumped as to why it won't fire up. Took filters off the carbs and operated throttle levers and can see fuel squirt.

    Any help appreciated :(
     
  9. Timing?
     
  10. That's what I thought, but how can I set it without starting it? Or should I just turn the dizzy slightly whilst cranking?

    cant you set it statically to 7.5 btdc and see what happens then dial it in better whence she runs?

    Dizzy could be 180 out?

    I'm very much looking forward to this.. In a non Pervy way

    HT leads wrong. I know you've checked them. :)

    Which should be in time to the revving of the engine. It's the law.

  16. Just checked the static timing and with no1 at tdc, scale read 7 deg to the right of zero, but the rotor arm was after no1 lead. I turned dizzy so they lined up but still didn't fire. Might be low battery now though after all the cracking for pressure and then all this trying to start. Put battery on charge for tomorrow

    Timing mark on pulley should be lined up with 7.5 degs anti-clockwise (left) of TDC (zero)

  18. Hmm. ......bugger. Got any inspiring suggestions @zed ?

    wind your pulley to the 7.5 btdc mark - you have set it to after top dead centre (atdc) then realign the dizzy to this.

    It may be you have got btdc and atdc muddled up :eek:

  20. Ok, so go almost 360 deg round again, but stop before piston reaches tdc, when timing mark lined up with 7.5 btdc. Then rotate dizzy body to match rotor arm with no lead?
