45D Base Plate

[julie4morris]

slightly confused over the base plate from the 45d off my marina 1275 engine. Surly with the vacuum advance will not work with the 'peg' in this position?[frame][/frame]

Does it all move by hand? Does the return spring hook over that peg? Sorry - but it's a while since I have been inside a 45D. Did you get revised dizzy mechanical advance settings to go with your new camshaft??

[julie4morris]

No none of it seems to move by hand and yes The link to the vacuum advance goes over peg. No but I shall ask for one

[bmcecosse]

The two parts should swivel on each other to allow the vacuum advance.

[julie4morris]

That's exactly what i thought looking up pictures of 45D base plats, but i found one that was like this. I think i will cut the peg out move it round then make up a new peg for the time being.

[bmcecosse]

NO! The two parts must swivel - concentrate on that. Do not cut the pin away - why would you do that???

[julie4morris]

No no I know, what I'm saying it that I will cut the pin away and I will then be able to swivel it around to the long slot where it can move freely under vacuum. When the pin is situated at the moment two parts are unable to swivel[frame][/frame]

i might be wrong but i think some marina's had a problem with over advanced timing under load and they modified the distributor to run no vacuum advance so this might be what you have or a lucas ''whoops''
