Hate me, I converted to carbs. Question about priming Options

[Literati914]

"Dr 914" is here to sell you parts. You are already on this forum, he should just answer up instead of asking you to mail him stuff. Why do you think you need an MPS with carbs? And why would a self proclaimed expert ask you to send him an FI part to troubleshoot your carb problem?

No, no, no.....This is when I had my FI installed. I was trying to narrow down an issue. Sorry I ever brought it up. My MPS has nothing to do with this thread.

Well it was cool of George to try and help, wouldn't you agree Rand?

I will work on the fuel pump not shutting off after I get this thing started.

My rotor goes clockwise and I have my plug wires firing in order. Is it suppose to fire off the #1 plug first every time and then move on to the #4, #3, #2?

I am getting backfires through both carbs while cranking. Does this mean I am not getting enough fuel? I have not adjusted either carb. From what the instructions showed, she should start and then you can fine tune.

Figure out where TDC on cyl #1 is. Use the engine cooling fan mark(s). What ever location the rotor is pointing to, respective of the cap terminals, should be where the #1 plug wire goes.

For the pump. Have a look at the classic thread forum and read andy's write up. Do it exactly the same way. It works.

the ground needs to be #3 not #4 as before mention.. to work with carbs ..
the second version pictured works for him , but the norm is ground #3

So basically, pull the black plug on the cooling fan and keep just slowly turn the ignition until I see the mark on the fan. Then look at the rotor button. That will tell me the #1 cylinder......Do I have that correct?

sounds like you need to static time engine from the beginning. turn engine until tdc on #1 on compression stroke. both rocker arms loose. rotor should be pointing at #1. if it is not, reclock distributor so that it is. check points are just opening with test light. replace cap, wire # 1 goes on that terminal, #4 wire next to it, #3 next and finally #2. that should get you close enough to start it. then time with a light once running. my carbed 1.7 runs best at 34 degrees btdc. the timing is set off the cylinder/stroke position, not distributor position. if distributor is clocked incorrectly you will be off.

Did you turn your engine over to TDC#1 before you started? If not then your distributor is probably improperly indexed/timed with TDC#1.

If you don't know where TDC#1 is, read the workshop manual for further clarification. At TDC#1 #1 piston should be at the top of it's stroke, and both valves should be fully closed, if you're not sure, then take the valve covers off and confirm. Also the rotor should point towards the front of the crankshaft.

No, I did not. This is a learning experience. I am trying to find the TDC mark now. I will post back when I do and see how things go from there.

Working on this now and will post back.

I found the TDC on my fan. Saw where my rotor button was pointing. Installed the cap and put the #1 spark plug wire to it, then #4, #3,#2.....Turned the ignition and SHE STARTED!!!!!!!!! (IMG:style_emoticons/default/piratenanner.gif)

She runs a little rough but now I can fine tune it. This is awesome....Thanks so much guys.

Now I have to work with this fuel pump staying on.

#1 - you need this jumper on your relay board (lower left):

#2. - you need to get a fuel pressure regulator and gauge and set the pressure to 3psi max.

My dual Weber 44's run fine with the above.

This didn't work in my case. Pump still stayed on.

You need to set the timing with the engine running now. Static timing is only good to get you in the ballpark. Now is the time to break out the timing light.

Where on the cap did #1 wind up? Normally it would be around 2 o'clock. Glad it started for you. You'll note in a picture in andy's write up the ground wire runs from the front one of the 2 jumped terminals to the ground post on the chassis forward of the relay plate.

Is there a "how to" or video on how to do that floating around this site?

Mine was closer to around the 4 o'clock spot if I remember correctly.

That is the way I did the ground. But when I leave it hooked up and turn off the key, the pump will stay on. I have to unplug that wire from ground to shut it off.
