Re: help sq 4 wont run

Well, I'm absolutely no Square Four expert but the main things I know of that can deteriorate with just sitting around are electrical. They also change characteristics from cold to hot. What does the ignition system have in the way of capacitors? (Someone will know :) ) Edit: Cripes, you might have ...

Re: 1932 mf

Seller: Rob Reaney - I did wonder a bit at the mention of a visit from 'VMCC members.... who might have wished me dead..'. in the listing. One of my formative moments was someone gifting a working twin mag to guest with a mag problem with the only 'cost' being 'pass it on' Herts branch ( I was a vis...

Re: Simes' FH Rebuild

Hi I have done away with the single small bolt between the inner primary chaincase and the tab on the front of that front FERC section The front attachment of my Fwd FERC is via a cage nut, out of interest, what caused you to dispense with this fastening point? Less things to loosen off and fall in...

Re: Cleaning oil tank

I cleaned out an oil tank with paraffin, the paraffin was just about coming out clean when I ran out and had to swap to petrol - which came out with massive amountws of still more crud.
Use something that's more aggressive than paraffin!

Re: Simes' FH Rebuild

I've got thick (standard) nuts on those two studs as well - it is a real fiddle putting them on but just about 'do-able'. I have done away with the single small bolt between the inner primary chaincase and the tab on the front of that front FERC section though - araldited a piece of beer can over th...

Re: Simes' FH Rebuild

Mick Dunno where the 25-tooth sprocket came from but I think most Ariel/BSA engine sprockets are pretty much the same so maybe it's from something like a Square 4. That 25t/44t combination will give you the same gearing as the earlier ('54/'55) FH 24t/42t setup which was ultimately considered a bit ...

Re: Simes' FH Rebuild

Two crankcase bolts (one front, one back) that don't have corresponding holes in the engine plates so have to be put in before the engine goes in the frame, and the engine plates fit over them. On mine the front one has very limited clearance to the engine plate on the drive side. I had new bolts fr...

Re: Simes' FH Rebuild

Simes: I don't think it matters which side of the frame plate you mount the oil tank, those plates can 'spring' easily enough anyway when everything is tightened up (probably a good thing). And easy enough to 'adjust' if necessary. My opinion, the seat bolt above the oil tank is too much of a fiddle...
