My 17" super colt (I think - perhaps super punch - anyway 98G14 engine) was a bit reluctant to start this season, so the obvious answer was to buy another completely non-working Marquis Mk4 20" (serial number DE716) ......which somehow feels like buying a jag as an upgrade to a cortina but perhaps I am being disloyal to Suffolk.
I think it has been 'stored outside' for a few years, but the engine turns over and it's basically complete. There is so much greasy grime on it that a lot of it seems in good condition underneath - obviously the exposed paintwork is a bit rough. One of the main rollers seems jammed, the other spins freely. There are only two front wooden rollers left and no grass box - which i have no doubt will cost me at least 5 times what the mower cost, but I think that stage is a long way off yet.
I was hoping for one of those 'despite being immersed in a bog for three decades, a splosh of fresh fuel, and a light going over with a feather duster and she started on the second pull' type of anecdotes. Unfortunately that is not the case.
I have a couple of questions:
1) There is no sign of a spark at all, despite vigorous pulls- either across spark gap or from end of HT lead. I saw a reference in another thread to a 'window' through the flywheel, but I cannot see it. Is the next stage to take off the flywheel and get at the points (or electronic ignition?) or are there other things I can try to do first? (I am desperately trying to avoid my 9 year old boy instinct to just take stuff apart willy nilly and end up with a pile of bits)
2) There is a sort of bracket thing on the back of the engine shroud that looks as if it may be meant to hold a spring, and perhaps rotate - is it some kind of choke mechanism?
3) Is the big disk a centrifugal clutch ?- if so it appears to be jammed as it always turns the drive shaft even when rotated slowly by hand.
In the meantime I will shove a scope camera down the plug hole and see if I can see the state of the inside of the cylinder, and drain the oil and refill it. I have squirted every visible nut and bolt with penetrating oil. I am considering buying an ultrasonic cleaner to clean the carb (and the zenith off the suffolk).
Thanks in advance - I know the depth of expertise to be found on this forum, and the willingness with which it is shared - I was last here asking questions about a kick start 2 stroke late 1950s Atco, in about 2009..... in the end I had to sell it - it was like driving a tank around a small lawn - noise, smell and fear.
