Timing problems on the 450 Bomber
Bryanj:
Ifvthe marks dont line up at tdc nothing you adjust will be right
K2-K6:
Worthwhile marking on the stator a true TDC mark as it's installed now...using marker pen / paint.
Then mark a F mark at static on the rotor to give (std setting, 14 btdc ? ) to be able to examine the trigger positions reference to this.
At least you'll see what you've got initially to then make decisions about what's wrong.
mo goldie:
are thanks all.
Ash if you can look tues will be good thanks,
Hi Roy yours I see the adjustment is what I had a problem with as I see on your picture that the base plate run out when it hit the washer on the Exhaust adjuster which is where mine hit, but even then the timing mark was way past the LF mark.
I also see your pick ups seem to be all in one so do they go from the two triggers right to the coils ? as Mine have two pickp ups and then go to two Modules which mount behind the Ign switch with two light on one Blue for left cylinder and one Green for the right Cylinder you are meant to time them up where the blue on the comp stroke just go`s off when it hit the LF mark as i say it go`s off but well after the TDC mark By about 1/4" .... but one all saying that don't understand why I can get a spark at the plugs......... they did want me to Buy a set of coils two but Mine by the looks of them are not that old, Idid go check today on the resistance and they both near the same as each other Pri left was 0.41 sec was 11.27 right coil was Pri 0.40 and Sec 11.66 .... but as I sat they were both running the engine when I went and picked it up..... the guy`s at Common Motors also wanted me to buy there Coils, but at anther $120 I gave them a miss..... but they say that their units will work on standard coils fitted but need to be a resistance of 5.0 so do you think this to be true ?
Hi K2
Yes I used a dial gauge and got top TDC and indeed it is past the LF by about 1/4" or so and I have put a marker pen make where TDC is..... still strange that I am Not getting a spark........ yes it was running on points before I put the E/I on and I No Nothing on how the engine was put together.
also one more thing if you look at my picture of the base plate you will see the dot on the cam is at the top should that be on the first blue pick up when its on ..or as mine is pasted the LF .... LT as mine it at the top when it near them.... so I tried to turn the advance unit round 180 to see if that made any differance but it did Not .... stummed :-X
AshimotoK0:
Mo...your standard coils will be 4.5 to 5.0 Ohms, so should be fine.
royhall:
Did you hear anything back from common motors? I think you need to chase down the no spark situation before anything else. If you can get it to run you can ignore the coloured timing lights and strobe it.
